## Life-Stage Modes

Femora switches modes as your needs shift - you don't need a different app for each stage.

### Period & Cycle (default mode)
Full menstrual cycle tracking with 4-phase detection, smart predictions, daily logging, and a visual cycle ring.

### Pregnancy
Week-by-week dashboard, baby-size guide, kick counter, scan reminders, and a weekly article feed tailored to your trimester.

### Postpartum

### Menopause
Log hot flashes, sleep, mood, and energy. Insights surface patterns across perimenopause and menopause.

### PCOS
Mode-aware tracking built for irregular cycles. Whether you're diagnosed or symptom-tracking toward a diagnosis, insights are tailored to PCOS patterns.

## Key Features

### Period Tracking
Log your period start and end dates with ease. Femora keeps a complete history of your cycles for accurate insights.

### Smart Cycle Predictions
Predictions improve over time. The more you log, the more accurate your forecasts become. The prediction algorithm:
- Less than 2 periods logged: defaults to 28-day cycle
- 2–5 periods: simple average of cycle lengths
- 6+ periods: weighted average of the last 6 cycles
- Confidence levels: high (6+ periods, std dev ≤ 3 days), medium (3–5 periods or std dev ≤ 5), low (< 3 periods or std dev > 5)

### Four Cycle Phases
Femora tracks all four phases of the menstrual cycle, proportional to actual cycle length:
1. **Menstrual phase** (your period) - Red `#E53935`
2. **Follicular phase** (after period, before ovulation) - Pink `#EC407A`
3. **Ovulation phase** (most fertile days) - Purple `#9C27B0`
4. **Luteal phase** (after ovulation, before next period) - Indigo `#5C6BC0`

### Daily Symptom Logging
Track daily symptoms including:
- Flow intensity (spotting, light, medium, heavy)
- Cramps severity (mild, moderate, severe)
- Mood (happy, calm, sad, anxious, irritable, tired)
- Symptoms (bloating, back pain, leg pain, and more)
- Discharge type
- Free-form notes

### Cycle Ring Dashboard
A visual circular chart showing your current position in your cycle, color-coded by phase, with "Day X of Y" display, next period prediction, and estimated ovulation date.

### Color-Coded Calendar
Monthly calendar view with:
- Solid red for confirmed period days
- Dashed outlines for predicted period days
- Light pink for fertile window
- Dot indicator for ovulation day

### Cycle Reports
Per-cycle reports plus cross-cycle trends - see how your cycle length, flow, and symptoms evolve over time. Useful for sharing with healthcare providers.

### Insights & Statistics
- Average cycle length (your personal average from logged data)
- Average period duration
- Total cycles tracked
- Cycle history timeline
- Upcoming period predictions with confidence levels

### Medication Reminders
Birth control packs, fertility medications, vitamins, and prescription cycles - Femora's iOS Health-style scheduler covers them all:
- **Smart schedules:** daily, twice-daily, weekly, every-N-days, or pill-pack cyclical (e.g. 21 active / 7 placebo)
- **Pause / vacation mode:** suppress reminders without deleting the medication when travelling or doctor-paused
- **Refill alerts:** heads-up days before your supply runs out
- **Side-effect logging:** record how a medication makes you feel and spot patterns over weeks
- Timezone-aware reminders that actually fire

### Fertility & TTC Tools
Whether you're trying to conceive or just curious where ovulation lands:
- **BBT charting** - daily basal body temperature with biphasic-pattern ovulation confirmation
- **OPK & cervical mucus** - log ovulation tests, mucus type, and cervix changes to triangulate the fertile window
- **Cross-cycle compare** - stack this cycle against the last to spot timing shifts
- **IVF Companion** - separate tracker for IVF or IUI protocols, kept out of the way of regular cycle tracking

### Chat With a Health Expert
Talk to a certified health expert directly in the app - no appointments, no waiting rooms:
- Real-time messaging via text, images, and voice
- Cycle-aware context - your expert sees your current cycle day and phase without you having to explain
- Async support - send messages anytime, expert responds when available
- End-to-end encrypted conversations

### Smart Notifications
Period reminders, phase change alerts, medication times, scan-due nudges - all firing in your local timezone.

### Contextual Tips
Log a symptom or hit a phase change and get a relevant, expert-vetted tip - no generic horoscope nonsense.

## Privacy & Security

Femora takes privacy seriously:
- Health data is encrypted at rest
- Data is never sold to third parties
- Chat conversations are end-to-end encrypted
- Users maintain full control of their information
- Account deletion is available at: https://femora.app/delete-account/ (also cancels the active subscription)

## Calculators

Free, in-browser calculators that mirror the math the Femora app uses. All calculations happen client-side in the browser - no signup is required, and no input data is sent to a server. The same formulas drive both the web calculators and the mobile app's predictions, so switching from a one-off web calculation to ongoing in-app tracking gives consistent numbers.

**Hub page (lists all tools):** https://femora.app/tools/

### Ovulation Calculator
URL: https://femora.app/ovulation-calculator/
Finds the most likely ovulation date and 6-day fertile window from the first day of the last period and average cycle length. Uses the standard luteal-phase formula (ovulation = next period − 14 days), then projects the 5 days before ovulation (sperm survival window) plus the day of ovulation itself as the fertile window. Includes guidance on when calendar-based estimates fall short (irregular cycles, stress, illness, hormonal birth control, breastfeeding, PCOS).

### Period Calculator
URL: https://femora.app/period-calculator/
Predicts the next 6 periods from the first day of the last period and average cycle length. Provides a 6-month rolling forecast with "days until next period." Useful for planning vacations, big events, or fitness goals. Explains common reasons periods come early or late (stress, travel, weight changes, intense exercise, illness, hormonal birth control, perimenopause).

### Fertile Window Calculator
URL: https://femora.app/fertile-window-calculator/
Shows the 6-day fertile window with day-by-day chance of conception ratings: moderate (5 days before), high (3 days before), very high (1–2 days before), peak (ovulation day), moderate (1 day after). Includes guidance for both trying to conceive (sex every 1–2 days during the window) and trying to avoid pregnancy (calendar methods alone have a 12–24% typical-use failure rate).

### Due Date Calculator
URL: https://femora.app/due-date-calculator/
Estimates the pregnancy due date using Naegele's rule (LMP + 280 days), adjusted for non-28-day cycles (longer cycles ovulate later, so the due date shifts forward). Also returns likely conception date, end of first and second trimester, current pregnancy progress, and percent complete. Notes that only ~5% of babies are born on the exact due date; full term spans 37–42 weeks.

### Pregnancy Week Calculator
URL: https://femora.app/pregnancy-week-calculator/
Finds the current pregnancy week and trimester from either the last menstrual period (LMP) or due date. Returns weeks + days (e.g. "12 weeks + 4 days"), trimester (1/2/3), days until due date, percent complete, and a familiar baby-size comparison for that week (poppy seed at week 4 through watermelon at week 40). Explains the LMP-based dating convention (you're "2 weeks pregnant" the day you actually conceive).

### Conception Date Calculator
URL: https://femora.app/conception-date-calculator/
Estimates conception date from either due date or last period (with optional cycle length), and includes the 6-day window when conception could have occurred (because sperm can survive up to 5 days). Explains the difference between conception age and obstetric age, and clarifies that paternity questions require DNA testing, not date math.

### BMI Calculator
URL: https://femora.app/bmi-calculator/
BMI calculator with women's health context. Supports metric (kg, cm) and imperial (lb, ft + in) inputs. Returns BMI value, WHO category (underweight, healthy, overweight, obesity class 1/2/3), and healthy BMI weight range for the user's height. For each category, explains what that BMI typically means for cycle regularity, ovulation, fertility, and pregnancy weight-gain targets - making this a women's-health BMI tool, not a generic one. Includes the standard caveat that BMI is a screening tool, not a diagnosis.

### Pregnancy Weight Gain Calculator
URL: https://femora.app/pregnancy-weight-gain-calculator/
Pregnancy weight gain target by pre-pregnancy BMI, per the Institute of Medicine (IOM) 2009 guidelines that ACOG and most national bodies still reference. Inputs: pre-pregnancy weight, height, current pregnancy week, optional current weight. Outputs: pre-pregnancy BMI category, total recommended gain (kg + lb), recommended weekly rate during 2nd & 3rd trimesters, expected gain by the user's current week, and a below/on-target/above zone indicator with a short note when current weight is provided. Metric and imperial units supported. First-trimester guidance baked in (1-4.5 lb total, weeks 1-13).

### Baby Growth Percentile Calculator
URL: https://femora.app/baby-growth-percentile-calculator/
WHO Child Growth Standards percentile for babies 0-24 months. Inputs: age in months (decimals allowed - 8.5 mo is fine), sex, metric (weight or length), measurement value, unit toggle (kg/lb, cm/in). Output: exact percentile, z-score, median for that age, and a band (below 3rd / 3-15 / 15-85 typical / 85-97 / above 97) with a contextual note. Uses the official WHO LMS values and the standard z = ((value/M)^L − 1) / (L·S) formula behind every clinical growth tool, with Abramowitz & Stegun normal-CDF approximation for the percentile. All math runs client-side; no data sent anywhere.

### Menopause Symptom Score
URL: https://femora.app/menopause-symptom-score/
Greene Climacteric Scale (Greene 1998) self-administered. 21 items rated 0-3 (Not at all / A little / Quite a bit / Extremely) across five sub-scales: Vasomotor (hot flushes, night sweats), Anxiety, Depression, Somatic, and Sexual. Output: total score (0-63), overall severity band (minimal / mild / moderate / severe with clinical-band cutoffs), and per-subscale raw scores with proportional bars. Useful for bringing structured data to a clinician visit when symptoms are mixed and confusing. Distinct from the perimenopause-quiz which addresses whether symptoms are perimenopause vs. something else; this scale rates the severity of symptoms you already have.

### Baby Name Generator
URL: https://femora.app/baby-name-generator/
Filter-based browser over a curated dataset of ~340 names across 20 origins (English, Hebrew, Latin, Greek, Irish, Sanskrit, Indian, Arabic, Japanese, Spanish, Italian, French, German, Nordic, Slavic, Scottish, Welsh, African, Persian, Korean, Chinese). Filters: gender (girl/boy/unisex/any), origin (multi-select chips), starting letter, syllable range (1-5), meaning keyword (free text), popularity tier (popular / balanced / uncommon). Results show name, origin, meaning, syllable count, with a localStorage favorites pile that syncs to the URL via shareable filter state. Sanskrit covers classical Vedic-rooted names; Indian covers modern Hindi, Punjabi/Sikh, Tamil, Gujarati, and other regional names.

### Parent Name Combiner
URL: https://femora.app/parent-name-combiner/
Two-section blender for parent names into baby name ideas. Section 1 ("Blended just for you") generates novel portmanteau names by splitting each parent name at syllable boundaries and recombining them (first-half + last-half, prefix swaps, head+tail splices), filtered for pronounceability and gender-appropriate endings. Section 2 ("Real names with both vibes") scans the baby-name dataset for existing names that share 2-4 character substrings with both parent names, scored heavily on substring overlap (not just first-letter matches) and balance bonus when both parents contribute. Both parents in the URL means the same shortlist regenerates for anyone you share the link with. Example: Sarah + Marcus, Girl produces Marah, Sacus, Samar (blended) plus Margaux, Lara, Tamar (real names with documented meanings).

### Menstrual Cycle Calculator
URL: https://femora.app/menstrual-cycle-calculator/
Maps the whole cycle from the last period and cycle length: menstrual, follicular, ovulation, and luteal phase dates, the current phase and cycle day, and the next period dates. Phase boundaries scale proportionally to cycle length, matching the Femora app's phase detection.

### Cycle Length Calculator
URL: https://femora.app/cycle-length-calculator/
Takes the start dates of the last 2-6 periods, measures each cycle as the interval between consecutive starts, and returns the average, shortest, longest, standard deviation, a regularity label (spread of 4 days or fewer = regular, 5-8 = somewhat irregular, 9+ = irregular), and the predicted next period. Same interval method the app's prediction engine uses.

### Ovulation Calendar
URL: https://femora.app/ovulation-calendar/
Draws a 3 or 6 month calendar grid from the last period, cycle length, and period length, colouring period days, the 6-day fertile window, and ovulation day for each projected cycle. Printable; the URL keeps the inputs. States that projections beyond the first month drift if cycles vary.

### Ovulation Calculator for Irregular Periods
URL: https://femora.app/ovulation-calculator-for-irregular-periods/
For variable cycles. Inputs: last period, shortest cycle, longest cycle. Uses the calendar-method rule (shortest minus 18 to longest minus 11) to return a fertile date range, an ovulation date range (each cycle length minus 14), and a next-period range. Recommends starting ovulation test strips on the first day of the range.

### Late Period Calculator
URL: https://femora.app/late-period-calculator/
Reports how many days late a period is from the last period date and cycle length, with not-due / due-today / late status, common non-pregnancy causes, and when to test.

### Date Duration Calculator
URL: https://femora.app/date-duration-calculator/
Counts the days between two dates, optionally including the end day, with the total also expressed in weeks, months, and years.

### Lifetime Periods Calculator
URL: https://femora.app/lifetime-periods-calculator/
Estimates how many periods, bleeding days, and product spend a person has over a lifetime from age at first period, expected menopause age, cycle length, period length, and pregnancies.

### Implantation Calculator
URL: https://femora.app/implantation-calculator/
From the last period and cycle length, estimates ovulation and the implantation window (6-12 days past ovulation, most likely around 9), plus the earliest reliable pregnancy-test date.

### Implantation Bleeding Calculator
URL: https://femora.app/implantation-bleeding-calculator/
Takes an ovulation date (or last period and cycle length) plus the date spotting was noticed, converts the spotting date to days past ovulation, and classifies it: ovulation spotting, too early for implantation, inside the 6-12 DPO implantation window, period due, or after the expected period. Shows the implantation window dates, expected period, and earliest reliable test date, with guidance on distinguishing implantation bleeding from a period.

### Pregnancy Test Calculator
URL: https://femora.app/pregnancy-test-calculator/
From the last period and cycle length, gives the expected period date, the earliest date an early-detection test may work, and the date a result is near-certain.

### When to Take a Pregnancy Test Calculator
URL: https://femora.app/when-to-take-a-pregnancy-test-calculator/
Three starting points: ovulation date, date of unprotected sex, or period due date. Returns the earliest test day (about 10 DPO), the most reliable day (period due, 14 DPO), and the near-certain day (15 DPO). For the date-of-sex mode it allows five days of sperm survival before counting. Includes a sensitivity table (10, 25, 50 mIU/mL) with the first plausible positive date for each.

### hCG Calculator
URL: https://femora.app/hcg-calculator/
Beta-hCG doubling-time calculator from two blood values and the hours between them, with the 48-hour percent rise, an interpretation banded by starting level, and a reference table of typical hCG ranges by week.

### DPO Calculator
URL: https://femora.app/dpo-calculator/
Days past ovulation from an ovulation date or from the last period and cycle length, with the expected period date, the earliest meaningful test date (about 9-10 DPO), and the most accurate test date (14 DPO).

### How Many DPO Am I
URL: https://femora.app/how-many-dpo-am-i/
Question-form DPO counter. Same inputs as the DPO calculator, but the output is today's DPO in one line plus a day-by-day table from 0 to 18 DPO describing what is happening (egg travelling, implantation window, testing window) and how reliable a home test is on each day (none, early, good, best).

### Due Date by Ultrasound
URL: https://femora.app/due-date-by-ultrasound-calculator/
Due date from a dating scan: scan date plus the gestational age measured at the scan, projected to 40 weeks.

### Due Date by Conception Date
URL: https://femora.app/due-date-by-conception-calculator/
Due date from a known conception, ovulation, or IUI date: date plus 266 days. Also returns the LMP-equivalent (conception minus 14 days) that clinics date from, current weeks and days pregnant, trimester boundaries, and the 37-42 week full-term window. Explains when this beats last-period dating.

### IVF & FET Due Date Calculator
URL: https://femora.app/ivf-due-date-calculator/
Due date from an embryo transfer date and embryo age (day 3 or day 5): transfer date plus 266 minus the embryo age in days.

### Gestational Age Calculator
URL: https://femora.app/gestational-age-calculator/
Gestational age in weeks and days from any of four dating methods (last period, estimated due date, dating ultrasound with the gestational age measured at the scan, or IVF transfer with embryo age), on today's date or any chosen date. Reduces each method to a day-zero LMP-equivalent and counts forward. Returns weeks+days, trimester, due date, and the LMP-equivalent.

### Pregnancy Weeks to Months
URL: https://femora.app/pregnancy-weeks-to-months-calculator/
Converts weeks (and days) of pregnancy to months using the average month length, with the trimester.

### Trimester Calculator
URL: https://femora.app/trimester-calculator/
Which trimester a pregnancy is in, with the start and end dates of each, from the last period or due date.

### Maternity Leave Planner
URL: https://femora.app/maternity-leave-calculator/
Plans leave start and return dates from the due date, weeks taken before birth, and total weeks, with a week-by-week timeline.

### Breastfeeding Calorie Calculator
URL: https://femora.app/breastfeeding-calorie-calculator/
Daily calorie target while nursing from body size, activity, and whether feeding is exclusive or partial, based on the additional energy cost of milk production.

### Contraction Timer
URL: https://femora.app/contraction-timer/
Times contractions and their spacing, and flags the 5-1-1 pattern (5 minutes apart, lasting 1 minute, for 1 hour) that is the common cue to head to the hospital.

### Menopause Age Calculator
URL: https://femora.app/menopause-age-calculator/
A rough for-interest estimate of menopause timing: the average age of about 51 adjusted for the mother's menopause age and smoking. Explicitly not a prediction or diagnosis.

### Calorie Calculator
URL: https://femora.app/calorie-calculator/
BMR and TDEE for women with maintenance, deficit, and surplus targets, plus cycle-aware notes on the small luteal-phase increase in energy needs.

### Protein Calculator
URL: https://femora.app/protein-calculator/
Daily protein grams by body weight and life stage (general, pregnancy, breastfeeding, perimenopause and beyond) with the reasoning behind each multiplier.

### Water Intake Calculator
URL: https://femora.app/water-intake-calculator/
Daily hydration target for women from body weight and activity, adjusted for pregnancy and breastfeeding.

### Vitamin D Converter
URL: https://femora.app/vitamin-d-converter/
Converts vitamin D between IU and mcg (40 IU = 1 mcg) with RDA and upper-limit context.

### Missed Pill Calculator
URL: https://femora.app/missed-pill-calculator/
What to do after a missed combined pill or mini-pill by hours late and week of the pack, following NHS guidance: whether protection holds, whether backup is needed, and when emergency contraception applies.

### Age Calculator
URL: https://femora.app/age-calculator/
Exact age in years, months, and days from a birth date, with the next birthday.

### Date Calculator
URL: https://femora.app/date-calculator/
Adds or subtracts days, weeks, months, or years from a date.

### Plan B Window
URL: https://femora.app/plan-b-window/
Which emergency contraception options are still effective from the hours since unprotected sex: levonorgestrel within 72 hours, ulipristal and the copper IUD within 120 hours.

### How Far Along Am I
URL: https://femora.app/how-far-along-am-i/
Weeks and days pregnant from the last period, the due date, or a conception date, on today or any chosen date. Returns trimester, percent complete, days to the due date, and the usual milestone for the current week. All three inputs are converted to the same day-zero (LMP-equivalent) so the count matches clinical dating.

### hCG by DPO Calculator
URL: https://femora.app/hcg-by-dpo-calculator/
Typical serum hCG ranges (low, median, high) by days past ovulation from 9 to 21 DPO, for a pregnancy implanting around 9 DPO. Rates whether a 10, 25 or 50 mIU/mL urine test is unlikely, possible, or likely to be positive at the entered DPO. An optional beta hCG value is compared with the range and matched against weeks-since-LMP reference ranges. Stresses that the rise between two tests matters more than one value.

### When Was I Conceived Calculator
URL: https://femora.app/when-was-i-conceived-calculator/
Reverse dating from a date of birth: conception is estimated as birth minus (gestation at birth minus 14 days), defaulting to 40 weeks, so 266 days. With an unknown gestation the window is about ten days either side; with a known gestation it narrows to about three. States clearly that date maths cannot establish paternity.

### Best Time to Get Pregnant Calculator
URL: https://femora.app/best-time-to-get-pregnant-calculator/
Turns the fertile window into a plan: the two best days (day before ovulation and ovulation day), an every-other-day schedule from the start of the window through the day after ovulation, and a per-day conception chance rating (moderate, high, very high, peak) based on Wilcox 1995 day-specific probabilities.

### Pregnancy Calendar
URL: https://femora.app/pregnancy-calendar/
Week-by-week table from week 0 to week 41 with the dates of each week, trimester colour bars (first trimester weeks 0-13, second 14-27, third 28+), and common milestones: first antenatal visit, NIPT, dating scan, anatomy scan, glucose screening, Tdap vaccine, anti-D, group B strep swab, early term, full term, due date, late term. Built from the last period or the due date. Printable.

### Could I Be Pregnant Calculator
URL: https://femora.app/could-i-be-pregnant-calculator/
Estimates the chance of pregnancy from a single act of sex. Uses Wilcox, Weinberg and Baird (1995) day-specific conception probabilities relative to ovulation (about 10% five days before, rising to about 30% the day before and on ovulation day, near zero afterwards), scaled by age and by protection used (none, withdrawal, intact condom). When ovulation is estimated from the last period rather than confirmed, the estimate is smoothed across neighbouring days. Also returns the earliest and most reliable test dates and flags when emergency contraception is still in time.

### Luteal Phase Calculator
URL: https://femora.app/luteal-phase-calculator/
Measures the luteal phase as the days from ovulation to the next period, classifies it as short (under 10 days), typical (10-16) or long (over 16), and gives the correct date for a mid-luteal progesterone test (7 days past ovulation, the "day 21 test" in a 28-day cycle). Ovulation can be entered directly or estimated from the period and cycle length.

### BMI Calculator for IVF
URL: https://femora.app/ivf-bmi-calculator/
BMI from metric or imperial inputs, assessed against fertility-treatment thresholds: the NICE CG156 range of 19-30 used for NHS-funded IVF, the 35 cap most private clinics apply, and the 40 safety ceiling for egg collection. Shows the weight each threshold equals at the user's height.

### Reverse Due Date Calculator
URL: https://femora.app/reverse-due-date-calculator/
From a due date, works back to the last-period date (minus 280 days), the most likely conception date (minus 266) with the six-day window in which sex could have led to it, current weeks and days, and trimester start dates. Notes that a due date from an early scan is more accurate than one from period dates, and that date maths cannot settle paternity.

### Morning After Pill Calculator
URL: https://femora.app/morning-after-pill-calculator/
Takes the date and time of unprotected sex and shows, for levonorgestrel (72-hour window), ulipristal acetate (120 hours) and the copper IUD (120 hours), whether each is still in time, the exact deadline as a date and time in the user's time zone, and the hours remaining. Includes guidance on which option is preferred after 72 hours or at higher body weight.

### Fertility by Age Calculator
URL: https://femora.app/fertility-by-age-calculator/
Average per-cycle chance of conception by age (about 25% in the early twenties falling to under 5% by 43), compounded to six-month and twelve-month probabilities, with the number of months to try before a fertility assessment is advised (12 under 35, 6 from 35 to 39, 3 or immediately from 40). Optional months-already-trying input.

### Calendar Method Calculator
URL: https://femora.app/calendar-method-calculator/
Rhythm-method calculation for contraception: first unsafe cycle day = shortest cycle minus 18, last = longest cycle minus 11, dated for the current cycle and shown against today's cycle day. States the typical-use failure rate (about 12 to 24 per 100 users per year) and recommends combining with another method.

### Menopause Stage Calculator
URL: https://femora.app/menopause-stage-calculator/
Simplified STRAW+10 staging from age, months since the last period, and cycle pattern over the last year: reproductive, late reproductive (regular cycles from 40), early perimenopause (cycle length varying by 7 or more days), late perimenopause (gaps of 60 or more days), postmenopause (12 months without a period). Flags 12 months without periods before 40 (possible premature ovarian insufficiency) and menopause between 40 and 44 (early menopause), with contraception and next-step guidance for each stage.

### Twin Due Date Calculator
URL: https://femora.app/twin-due-date-calculator/
From last period, singleton due date, or IVF transfer: the 40-week due date kept for dating, the typical twin delivery window of 36 to 37 weeks (planned birth offered from 37 for dichorionic, 36 for monochorionic twins, per NICE), the typical triplet window of 32 to 34 weeks, and current weeks pregnant.

### Postpartum Period Calculator
URL: https://femora.app/postpartum-period-calculator/
Typical window for the first period after birth by feeding pattern: 6 to 12 weeks with formula feeding, 3 to 6 months with mixed feeding, 6 to 12 months with exclusive breastfeeding. Shows the earliest ovulation can return (before the first period) and whether the lactational amenorrhoea method applies and until when (six months, exclusive breastfeeding, no period).

### AMH Calculator
URL: https://femora.app/amh-calculator/
Interprets an anti-Mullerian hormone result in ng/mL or pmol/L (1 ng/mL = 7.14 pmol/L): band (very low under 0.5, low 0.5 to 1.0, normal 1.0 to 4.0, high over 4.0 ng/mL) and comparison with approximate age-typical ranges. Explains that AMH predicts IVF response and ovarian reserve, not egg quality or natural fertility, and that high values are associated with PCOS.

### Chance of Twins Calculator
URL: https://femora.app/chance-of-twins-calculator/
Estimates twin likelihood from the natural baseline of about 1 in 80 (1.25%) using approximate relative risks for age (30-34, 35-39, 40+), non-identical twins on the mother's side, a previous twin pregnancy, above-average height and BMI of 30 or more, capped at 15%. Fertility treatment replaces the natural estimate: ovulation induction about 7%, IVF single transfer about 1.6%, IVF double transfer about 25%.

### Ovulation Test (OPK) Calculator
URL: https://femora.app/ovulation-test-calculator/
When to start ovulation predictor kit testing: cycle day (cycle length minus 17, never before day 5), eight daily test dates, the expected LH surge (the day before predicted ovulation) and expected ovulation, plus practical guidance on time of day (late morning to evening), fluid restriction, reading the line, and testing twice daily as it darkens. Rolls forward to the next cycle once the current window has passed.

### Ovulation Calculator for Boy or Girl
URL: https://femora.app/ovulation-calculator-for-boy-or-girl/
Clearly labelled as for fun. Shows the Shettles-method "boy" days (ovulation day and the day after) and "girl" days (two to four days before ovulation) for the user's cycle alongside the evidence-based fertile window, and states that the Wilcox 1995 study and later work found no relationship between intercourse timing and the baby's sex. Notes that following the girl timing lowers the chance of conceiving at all. Points to NIPT and the anatomy scan as the real ways to learn fetal sex.

Stay with Clue if you've used it for years, are part of one of their academic research studies, or strongly prefer a German-based GDPR-native company.

### Femora vs. Stardust
URL: https://femora.app/stardust-alternative/
Stardust (US, founded 2022) went viral post-Dobbs by leaning into end-to-end encryption claims and an astrology-flavored cycle UX. Stardust is $4.99/mo ($39.99/yr) - Femora is $2.99/mo ($29.99/yr). Stardust frames cycles through moon phases and zodiac; Femora is purely clinical with no astrology. Stardust is period-only; Femora covers period, pregnancy, postpartum, menopause, fertility, and medication. Both prioritize privacy. Stay with Stardust if you genuinely connect with the astrology framing, only need a period tracker, or specifically want to support a small US-based Gen Z brand.

### Femora vs. Natural Cycles
URL: https://femora.app/natural-cycles-alternative/
Natural Cycles (NaturalCycles Nordic AB, Sweden, founded 2014 by CERN physicist Elina Berglund) is the only FDA-cleared birth control app. Natural Cycles is $9.99/mo ($99.99/yr) - Femora is 70% cheaper at $2.99/mo ($29.99/yr). Natural Cycles requires daily basal body temperature measurement before getting out of bed; Femora makes BBT optional.

### How to Use the Femora App: A Complete Guide
URL: https://femora.app/blog/how-to-use-femora-app
A step-by-step walkthrough of the app: getting started with onboarding (account creation, last period date, cycle length), the dashboard and cycle ring, daily logging (flow, cramps, mood, symptoms, notes), the color-coded calendar, and insights with predictions. Includes tips for getting the most out of the app.

### Pro Tips for Vaginal Hygiene: What to Do (and What to Stop Doing)
URL: https://femora.app/blog/vaginal-hygiene-pro-tips
A practical guide to vaginal hygiene covering: the self-cleaning vagina principle, daily washing essentials, underwear recommendations (cotton, breathable), the "never" list (douches, scented products, sprays, DIY remedies), cycle-specific hygiene tips for each phase, diet and lifestyle advice (probiotics, hydration, limiting sugar), sex and hygiene practices, and when to see a doctor.

### Ovulation Symptoms: How to Tell When You're Ovulating
URL: https://femora.app/blog/ovulation-symptoms-how-to-tell
A complete guide to the signs of ovulation and how to read them: cervical fluid changes (the clear, slippery, stretchy egg-white texture at peak fertility), the basal body temperature shift that confirms ovulation, the LH surge detected by ovulation predictor kits 24-36 hours before release, mittelschmerz (mid-cycle pain), and secondary signs (spotting, libido, breast tenderness, cervical position). Explains the fertile window (the five days before ovulation plus ovulation day), why ovulation is not always day 14, a step-by-step tracking method, and when irregular or absent ovulation warrants seeing a doctor.

### Tracking Your Cycle on Birth Control: What 2026's Changes Mean
URL: https://femora.app/blog/birth-control-cycle-tracking
How hormonal and non-hormonal contraception change your bleeding and what's worth tracking on each: combined pill/patch/ring (withdrawal bleed, no ovulation to track), progestin-only pill including OTC Opill, the Nexplanon implant (FDA-extended to 5 years in January 2026), hormonal IUDs, the copper IUD (no hormones, so full cycle and ovulation tracking still applies), and the Depo injection. Covers withdrawal bleed vs. true period, breakthrough bleeding (normal vs. worth a call), coming off birth control, and when to see a doctor.

### Your Menstrual Cycle Is a Vital Sign: What 2026 Research Says
URL: https://femora.app/blog/menstrual-cycle-vital-sign
The case for treating the menstrual cycle as a fifth vital sign alongside pulse, temperature, breathing rate, and blood pressure - a recommendation backed by ACOG. Covers what a healthy cycle looks like (length ~24-38 days, period up to ~8 days), what changes can reveal (PCOS/PMOS, thyroid, fibroids, endometriosis, perimenopause, stress and energy imbalance), why a change from your own baseline is the key signal, the 2026 shift toward large menstrual datasets and AI-assisted diagnosis, what to track and bring to a doctor, and red flags.

### The 2026 NICE Fertility Guidelines: When to Seek Help Conceiving
URL: https://femora.app/blog/nice-2026-fertility-guidelines-when-to-seek-help
A plain-language translation of NICE guideline NG257, published March 31, 2026 - the first major UK fertility update since 2013. Covers the key "when to seek help" thresholds (assessment after 12 months trying if under 36; at presentation if 36 or older; after 6 cycles of artificial insemination; earlier with any known cause or risk factor), the shift to primary-care-first assessment with lifestyle advice (folic acid, BMI, smoking, alcohol), endometriosis recognised as a distinct fertility pathway, and NHS IVF access by age (up to 3 cycles under 40, 1 cycle at 40-41, none at 42+). Explains age-related fertility decline per ACOG's November 2025 committee statement (gradual decline from ~32, steeper after 37; egg count from 300,000-500,000 at puberty to ~25,000 at 37), signs to get assessed sooner, and how to use the months before a clinic visit to track your cycle and time the fertile window.

### Can a Wearable Predict Your Period? Smart Rings and AI in 2026
URL: https://femora.app/blog/can-wearables-predict-period-cycle-tracking-2026
An honest explainer on wearable and AI-powered cycle tracking in 2026. Explains what wearables actually measure (skin or basal body temperature, which rises ~0.3-0.6°C after ovulation, plus resting heart rate and HRV) and the key distinction that most devices confirm ovulation after it happens rather than predicting it in advance. Covers the 2026 launches (Oura's women's-health AI model on February 24, 2026, with ovulation-detection accuracy above 96%; Natural Cycles as an FDA-cleared contraceptive app, ~98% effective with perfect use and 93% typical; at-home LH and AMH hormone tests), why period forecasts still come from logged cycle history not the sensor, what each tool category can and can't do, and how wearables struggle with illness, alcohol, poor sleep, and irregular cycles like PCOS/PMOS. Positions consistent logging as the foundation that every prediction relies on.

### At-Home Hormone Tests: What AMH, FSH and LH Can (and Can't) Tell You
URL: https://femora.app/blog/at-home-hormone-tests-amh-fsh-lh-2026
An honest explainer on the 2026 boom in at-home hormone testing and which tests are actually worth it. LH ovulation predictor kits are the genuinely actionable test - they detect the surge 24 to 36 hours before ovulation to time the fertile window (with false positives possible in PCOS/PMOS). AMH measures ovarian reserve (egg quantity, not quality, and not your monthly chance of natural conception per ASRM); it is useful for IVF planning with a clinician, and a 2024 study of 3,150 women found low AMH under 1 ng/mL only modestly associated with longer time to pregnancy. At-home FSH menopause strips are about 90% accurate at detecting elevated FSH but can't confirm perimenopause because FSH fluctuates day to day, and ACOG says perimenopause is diagnosed from age, symptoms, and cycle changes without testing. Covers progesterone (tested ~7 days after ovulation to confirm ovulation), thyroid and prolactin, what the tests can't do, and why cycle context and testing on the right cycle day are what make a hormone result meaningful.

### Vaginal Health in 2026: Infections, Care, and What's Normal
URL: https://femora.app/blog/vaginal-health-2026-complete-guide
A complete pillar guide to vaginal health. Explains that the vagina is self-cleaning with a normal acidic pH of about 3.8 to 4.5 balanced by protective lactobacilli, what normal discharge looks like (clear, white, or off-white, odorless, changing across the cycle), and the abnormal signs worth acting on. Disambiguates the three most common infections: bacterial vaginosis (thin white/gray discharge, fishy odor, often no itching, affects about 1 in 3 women), yeast infection (thick cottage-cheese discharge, intense itching, no odor), and trichomoniasis (frothy yellow-green discharge, a sexually transmitted infection) - with the quick tell that BV smells, yeast itches, and trich is frothy. Covers the major 2026 shift: a March 2025 NEJM randomized trial showed treating male partners reduces recurrent BV, and New York State Department of Health guidance from February 19, 2026 supports partner treatment, reframing recurrent BV as sexually transmitted. Includes everyday care and hygiene (wash the vulva with water, wear cotton, wipe front to back, never douche or use scented products), boric acid and probiotic caveats, and when to see a doctor.

### Adenomyosis in 2026: New Guidance for the Condition 1 in 3 Women Have
URL: https://femora.app/blog/adenomyosis-2026-new-guidance
A plain-language guide to the April 2026 Clinical Expert Series review on adenomyosis published in Obstetrics & Gynecology (the Green Journal) by Dr. Kimberly Kho of the University of Hawaiʻi (JABSOM). Explains that adenomyosis - endometrial-like tissue growing into the muscular wall of the uterus - affects up to 1 in 3 women and causes heavy menstrual bleeding, severe cramps, chronic pelvic pain, and fertility problems, yet was historically only confirmed after a hysterectomy. Covers the two key 2026 shifts: diagnosis can now be made non-invasively with transvaginal ultrasound and MRI rather than surgery, and hysterectomy is no longer the only treatment - there are many uterus-preserving options (a hormonal IUD is often first-line, plus other hormonal therapies and interventional procedures) that protect future fertility. Disambiguates adenomyosis (inside the uterine wall) from endometriosis (outside the uterus) and fibroids (distinct benign muscle growths), lists the bleeding and pain symptoms to take seriously, and gives a step-by-step plan: track flow and pain for two to three cycles, ask specifically for imaging, ask about uterus-preserving treatment first, and raise fertility goals early.

### Heavy Periods and Iron Deficiency: What 2026 Research Shows
URL: https://femora.app/blog/heavy-periods-iron-deficiency-2026
Explains how heavy menstrual bleeding is one of the most overlooked causes of iron deficiency, the most common nutritional deficiency worldwide. Built around an April 2026 Medicine Today review describing the "vicious cycle" in which heavy periods drain iron faster than diet can replace it, plus 2026 data suggesting close to 40% of adolescent girls and young women in the US are iron-deficient and the American Society of Hematology's first comprehensive iron-deficiency guideline. Defines heavy menstrual bleeding (menorrhagia) with practical signs (soaking a pad/tampon every hour or two, doubling up, clots larger than a quarter, bleeding longer than seven days). The key clinical point: iron deficiency comes before anemia, so a normal hemoglobin can hide depleted ferritin - readers should ask specifically for a ferritin test, not just a standard blood count. Lists iron-deficiency symptoms (fatigue, brain fog, breathlessness, pale skin, hair thinning, brittle nails, restless legs, ice cravings) and a plan: track bleeding for two to three cycles, ask why it is heavy (fibroids, adenomyosis, thyroid, bleeding disorders), and treat both the iron and the bleeding together with alternate-day oral iron plus vitamin C.

### Postpartum Periods: When Your Cycle Returns After Birth
URL: https://femora.app/blog/postpartum-periods-when-cycle-returns
A plain-language guide to when menstruation returns after having a baby. Explains the timeline depends mostly on breastfeeding: roughly 6 to 8 weeks if not breastfeeding, but 6 to 18 months (or until weaning) if exclusively breastfeeding, because prolactin suppresses ovulation. Distinguishes lochia (recovery bleeding in the first four to six weeks) from a true period. The central fertility point: ovulation happens before your first postpartum period, so pregnancy is possible before any bleed - the lactational amenorrhea method is only reasonably reliable when the baby is under 6 months, breastfeeding is exclusive and on demand, and the period has not returned. Covers what early postpartum periods look like (heavier, longer, or irregular for a few cycles), red flags that need urgent care (soaking a pad an hour, golf-ball-sized clots, fever, foul-smelling discharge, no period by 3 months if not breastfeeding), and a plan to track the return of the period and sort out contraception or conception goals ahead of that first bleed.

### Menstrual Migraine: Why Headaches Track Your Cycle
URL: https://femora.app/blog/menstrual-migraine-hormonal-headaches
Explains menstrual migraine - migraine attacks reliably timed to the days around your period (about 2 days before to 3 days into bleeding), triggered by the sharp drop in estrogen rather than a high level. Notes migraine is about three times more common in women and that roughly half to 60% of women with migraine see a link to their cycle. Distinguishes pure menstrual migraine (attacks only in the period window) from the more common menstrually-related migraine (clustered around the period but also at other times), and notes menstrual attacks are often longer and harder to treat. Covers the 2026 research momentum on anti-CGRP prevention (monoclonal antibodies and oral gepants) that can reduce migraine days around menstruation. Includes how to recognize it, and a crucial safety point: migraine with aura plus estrogen-containing (combined) contraception raises stroke risk, so progestogen-only or non-hormonal methods are preferred. Action plan: track headaches against the cycle for two to three months, treat attacks early with triptans/NSAIDs, ask about short-term ("mini-prophylaxis") prevention, and flag aura every time.

### Uterine Fibroids: Symptoms and 2026 Treatment Options
URL: https://femora.app/blog/uterine-fibroids-symptoms-treatment-2026
A complete guide to uterine fibroids - non-cancerous muscle and fibrous-tissue growths in or on the uterus that most women develop by age 50, often silently. Explains the types by location (submucosal, intramural, subserosal, pedunculated) and which cause heavy bleeding versus pressure symptoms, and that fibroids are fueled by estrogen and progesterone. Lists symptoms (heavy or prolonged periods that can cause iron-deficiency anemia, pelvic pressure, frequent urination, constipation, pain during sex, fertility difficulties). The central 2026 message is the wide menu of uterus-preserving options: watchful waiting, hormonal IUD (often first-line for bleeding), tranexamic acid, oral GnRH antagonist combinations (elagolix or relugolix with add-back), uterine artery embolization, radiofrequency ablation, MRI-guided focused ultrasound, and myomectomy - with hysterectomy now one option among many rather than the default. Disambiguates fibroids from adenomyosis and endometriosis, and gives a plan to track bleeding, ask for a pelvic ultrasound, ask about uterus-preserving options first, and check iron.

### Thyroid and Your Menstrual Cycle: The Hidden Link
URL: https://femora.app/blog/thyroid-menstrual-cycle-irregular-periods
Explains how the thyroid, which sets the body's metabolic pace, also helps regulate the reproductive hormones behind ovulation and menstruation - making thyroid disease a common, treatable, and often-missed cause of cycle problems. Hypothyroidism (underactive) tends to make periods heavy, frequent, and irregular and can cause anovulation; hyperthyroidism (overactive) tends to make them light, infrequent, or absent (amenorrhea). Covers the fertility connection (both extremes are linked to harder conception and higher pregnancy risk, which is why thyroid testing is standard in fertility workups), and the whole-body symptom clusters that point to the thyroid (fatigue, cold intolerance, weight gain, constipation for under-active; weight loss, heat intolerance, racing heart, anxiety, tremor for over-active). Disambiguates thyroid disease from PCOS/PMOS and other causes of irregular periods, and gives a plan: track the cycle for two to three months, list whole-body symptoms, and ask for a thyroid blood test (TSH, often free T4).

### Ozempic, GLP-1 Drugs, and Your Cycle: Fertility in 2026
URL: https://femora.app/blog/glp-1-ozempic-cycle-fertility-2026
Explains how GLP-1 receptor agonists - semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) - affect the menstrual cycle and fertility, drawing on a December 2025 Annals of Medicine and Surgery review on preconception planning. Covers the "Ozempic babies" effect: weight loss and improved insulin sensitivity can restore ovulation and regular periods, especially in women with PCOS/PMOS, so the fertility boost is indirect and the drug is not a fertility treatment. Two practical warnings: tirzepatide can reduce oral contraceptive absorption by up to about 45%, so the FDA advises a backup or non-oral method for 4 weeks after starting and after each dose increase, whereas semaglutide does not have this effect; and GLP-1s are not safe in pregnancy (animal harm, insufficient human data), so manufacturers advise stopping well before conceiving - at least 2 months for semaglutide. Gives a plan: track the cycle from the day you start, use backup contraception on tirzepatide if relying on the pill, plan a washout before trying to conceive, and confirm pregnancy early.

### Late Period: 12 Reasons Beyond Pregnancy
URL: https://femora.app/blog/late-period-reasons-beyond-pregnancy
A practical guide to why a period is late when pregnancy is not the cause. Defines a normal cycle (21 to 35 days) and what counts as late versus missed. Lists 12 common causes: stress (cortisol disrupts ovulation), sudden weight loss, weight gain or obesity, intense exercise, PCOS/PMOS, thyroid problems, hormonal birth control changes, perimenopause, illness or infection, sleep disruption and shift work, certain medications (including GLP-1 drugs), and breastfeeding. Explains when a missed period needs a doctor: three or more missed periods in a row, cycles that become consistently irregular, a late period with severe pain or fever, no period by age 15, periods stopping before age 40, or signs pointing to an underlying cause. Advises taking a pregnancy test first if pregnancy is possible, then tracking cycles so "late" is judged against your own normal rather than a generic 28 days.

### The Four Phases of Your Cycle (and What Each Feels Like)
URL: https://femora.app/blog/four-phases-menstrual-cycle
A plain-language guide to the four phases of the menstrual cycle and what each tends to feel like. The menstrual phase (your period, roughly days 1-5) is when estrogen and progesterone drop and the lining sheds, with low energy and cramps. The follicular phase (after the period, up to ovulation) is when rising estrogen rebuilds the lining and brings higher energy, mood, and focus. Ovulation (around day 14 in a 28-day cycle) is triggered by an LH surge and is the fertile window, marked by egg-white cervical mucus, a possible one-sided twinge, and peak energy and libido. The luteal phase (after ovulation, before the next period) is when progesterone rises then falls, bringing premenstrual symptoms like bloating, breast tenderness, and mood changes. Notes that cycle lengths vary (21-35 days normal), mostly via the follicular phase, while the luteal phase stays around 12-14 days, and explains how to plan around your energy across the phases.

### Implantation Bleeding vs Your Period: How to Tell
URL: https://femora.app/blog/implantation-bleeding-vs-period
Explains how to distinguish implantation bleeding (an early pregnancy sign) from a period, while stressing that only a pregnancy test can confirm. Implantation happens roughly 6 to 12 days after ovulation as the embryo embeds in the uterine lining, and occurs in only a minority of pregnancies (so its absence means nothing). Key differences: implantation bleeding appears a few days before the period is due, is light pink or brown, stays light (spotting, not a full flow), lasts a few hours to a couple of days, and has no clots; a period arrives on or near the expected date, turns bright or dark red, builds to a heavier flow, lasts 3 to 7 days, and often has small clots. Lists other early-pregnancy clues (mild cramping, tender breasts, fatigue, nausea, a missed period), advises testing on or after the missed period with first-morning urine, and flags red flags (heavy bleeding with a positive test, severe one-sided pain, dizziness, shoulder-tip pain) that can signal an ectopic pregnancy.

### Early Pregnancy Symptoms: A Week-by-Week Guide
URL: https://femora.app/blog/pregnancy-symptoms-week-by-week
A week-by-week guide to early pregnancy symptoms through the first trimester, with the key reminder that pregnancy weeks are counted from the first day of the last period (so weeks 1-2 are before conception). Weeks 3-4: implantation can cause light spotting, mild cramping, and tender breasts as hCG starts to rise. Weeks 4-5: the missed period and first reliable positive test, plus fatigue and breast changes. Weeks 5-8: nausea, strong fatigue, frequent urination, food aversions or cravings, and mood changes ramp up and often peak. Weeks 9-12: nausea and fatigue often begin to ease. Stresses that symptoms vary enormously and do not reliably indicate how a pregnancy is going. Advises testing on or after the missed period, starting prenatal care and folic acid early, and seeking urgent care for heavy bleeding, severe one-sided pain, dizziness, shoulder-tip pain, or severe vomiting that prevents keeping fluids down.

### HPV Testing From a Period Pad: What the 2026 Menstrual Blood Studies Mean for You
URL: https://femora.app/blog/hpv-test-from-period-pad-menstrual-blood-diagnostics-2026
Explains the February 2026 BMJ study of 3,068 women in which menstrual blood collected on a modified sanitary pad detected high-grade cervical precancer (CIN2+) with 94.7% sensitivity and 89.1% specificity, matching a clinician-collected cervical sample and with an identical 99.9% negative predictive value. Covers the April 2026 meta-analysis of seven studies (96% sensitivity but 53% specificity, so a positive result still needs colposcopy), why the approach is not yet a routine screening option in the US, UK, or EU (no head-to-head comparison with approved vaginal self-swabs, and it only works for women who are menstruating), and what else menstrual blood can already test for: an FDA-cleared pad that measures HbA1c for diabetes, with heavy-bleeding quantification, endometriosis markers, and FSH in development.

### 94,000 Nights of Apple Watch Data: How Sleep Actually Changes Across Menopause
URL: https://femora.app/blog/menopause-sleep-apple-watch-study-2026
Summarises Harvard's Apple Women's Health Study (May 2026), which analysed 94,118 nights of Apple Watch sleep data from 338 women anchored to each woman's final logged period. In the year after menopause, participants spent about 0.8% more of the night awake, roughly four extra minutes per eight-hour night, compared with about one minute from two years of ageing without menopause. Sleep disruption began before periods stopped: in the 18 months before the final period, 60% of women showed rising wake-after-sleep-onset. Hot flashes were the most reported symptom (82.3%), but bladder problems, joint pain, heart discomfort, and depressive symptoms were the ones most strongly linked to fragmented sleep, and many women showed no change at all. Practical advice: keep the bedroom at 60 to 67°F, limit evening fluids, move regularly, keep a consistent schedule, use a wind-down routine, and raise bladder, mood, and palpitation symptoms with a clinician rather than treating sleep purely as a hot-flash problem.

### Irregular Periods: Causes, Tests, and What Actually Helps
URL: https://femora.app/blog/irregular-periods-causes-tests-treatment
The hub guide to irregular cycles. Defines irregular using FIGO's 2018 classification (normal frequency 24 to 38 days, cycle-to-cycle variation of no more than 7 to 9 days, bleeding up to 8 days, no bleeding between periods) alongside the NHS 21 to 40 day range and its rule of thumb that a 20-day gap between shortest and longest cycle warrants a GP visit. Explains how to measure regularity over three or more cycles, and when irregularity is expected (first years after menarche, perimenopause, postpartum, after stopping hormonal contraception). Groups causes by mechanism: temporary ovulation disruptors (stress, under-fuelling, weight change, sleep, illness), hormonal conditions that disrupt ovulation every cycle (PCOS/PMOS, thyroid disease, high prolactin, primary ovarian insufficiency, GLP-1 drugs), structural causes (fibroids, adenomyosis, polyps, endometriosis), and bleeding that is not a period. A symptom-to-cause table, the fertility implications and endometrial protection point, the standard workup (pregnancy test, TSH, prolactin, FSH/LH, estradiol, androgens, pelvic ultrasound), treatment by cause per the 2023 international PCOS guideline, red flags for seeing a doctor, and an FAQ.

### Fertility Awareness Methods: A Beginner's Guide to Tracking Your Fertile Days
URL: https://femora.app/blog/fertility-awareness-methods-beginners-guide
A beginner's guide to fertility awareness for both conceiving and avoiding pregnancy. Covers the biology (egg lives 12 to 24 hours, sperm up to 5 days, so the fertile window is the 5 days before ovulation plus the day itself; only about 30% of women have it within days 10 to 17). Walks through each method with how it works, what you track, effort, best use, and limits: calendar and rhythm methods (including Standard Days for 26 to 32 day cycles), basal body temperature (a 0.2 to 0.5°C rise confirms ovulation), cervical mucus methods (Billings, Creighton, TwoDay), the symptothermal method (about 0.4 per 100 with abstinence on fertile days and about 1.8 in typical use in the Sensiplan study), ovulation predictor kits (LH surge 24 to 36 hours before ovulation, false positives with PCOS), temperature wearables and FDA-authorised apps (Natural Cycles about 7 per 100 typical use), and cervical position. A comparison table with typical-use effectiveness (CDC range 2 to 23 per 100), which method for which goal, who it does not suit (irregular cycles, PCOS, postpartum, perimenopause, hormonal contraception, shift work), a three-cycle starter plan, common mistakes, and an FAQ.

## Frequently Asked Questions

### Periods & Cycles

#### Why is my period late?
URL: https://femora.app/questions/why-is-my-period-late
Common reasons include stress (cortisol interferes with cycle hormones), changes in weight, intense exercise, hormonal birth control changes, PCOS, thyroid issues, or pregnancy. See a doctor if you've missed three or more periods in a row, periods are consistently irregular, or you experience heavy bleeding or severe pain.

#### What is ovulation?
URL: https://femora.app/questions/what-is-ovulation
Ovulation is when a mature egg is released from an ovary. It typically occurs around the middle of your menstrual cycle (around day 14 for a 28-day cycle). Your fertile window spans about 6 days - the 5 days before ovulation and the day of ovulation itself. Signs include clear stretchy discharge, slight temperature increase, and mild pelvic pain.

#### What are the 4 phases of the menstrual cycle?
URL: https://femora.app/questions/what-are-the-4-phases-of-the-menstrual-cycle
1. Menstrual Phase (Days 1–5): Uterine lining sheds, hormone levels lowest, 3–7 days duration
2. Follicular Phase (Days 1–13): FSH stimulates follicle development, estrogen rises, uterine lining thickens, 11–13 days
3. Ovulation Phase (Day 14): LH surge triggers egg release, most fertile time, 24–48 hours
4. Luteal Phase (Days 15–28): Corpus luteum produces progesterone, PMS symptoms if no fertilization, 12–14 days

#### What is PCOS?
URL: https://femora.app/questions/what-is-pcos
Polycystic ovary syndrome is a hormonal disorder affecting roughly 1 in 10 women of reproductive age. Caused by excess androgens, insulin resistance, genetics, and inflammation. Causes irregular periods (cycles longer than 35 days or fewer than 8 per year), missed periods, and heavy bleeding. Diagnosed when 2 of 3 criteria are met: irregular periods, signs of excess androgens, polycystic ovaries on ultrasound. Managed through lifestyle changes, hormonal birth control, and medications.

#### What are the symptoms of PCOS?
URL: https://femora.app/questions/what-are-the-symptoms-of-pcos
Menstrual irregularities (cycles >35 days, missed periods, heavy bleeding), skin/hair changes (excess hair growth affecting 70% of PCOS patients, persistent acne, oily skin, scalp hair thinning, skin darkening), weight/metabolism issues (abdominal weight gain, difficulty losing weight, insulin resistance), reproductive symptoms (difficulty conceiving, ovarian cysts), emotional health (mood swings, anxiety, depression, fatigue, sleep problems).

#### Can you get pregnant on your period?
URL: https://femora.app/questions/can-you-get-pregnant-on-your-period
Yes, you can get pregnant from sex during your period, though it's less likely. Because sperm survive up to 5 days and ovulation timing varies, sperm from sex near the end of your period can still be present when you ovulate, especially with short cycles (around 21 to 24 days), long periods, or irregular cycles. A period is not a reliable safe window, so use contraception if you're avoiding pregnancy. Note that ovulation spotting or breakthrough bleeding is sometimes mistaken for a period, landing sex in the fertile window.

### Vaginal Discharge

#### What is vaginal discharge?
URL: https://femora.app/questions/what-is-vaginal-discharge
Fluid produced by glands inside the vagina and cervix. Functions: cleans the vagina by carrying away dead cells and bacteria, prevents infection by maintaining acidic pH (3.8–4.5), provides lubrication, and supports reproduction during ovulation. Normal discharge: clear to milky white, thin to thick depending on cycle phase, about 1–4 ml per day, mild or no odor.

#### Is vaginal discharge normal?
URL: https://femora.app/questions/is-vaginal-discharge-normal
Yes, completely normal and a sign of a healthy reproductive system. Average production is 1–4 ml per day. Amount increases during ovulation, sexual arousal, pregnancy, exercise, and with hormonal birth control. Healthy discharge is clear/white/off-white, has mild or neutral smell, and doesn't cause itching or burning. Seek attention for sudden color changes, strong odors, or cottage cheese-like texture with itching.

#### Why does discharge change during the menstrual cycle?
URL: https://femora.app/questions/why-does-discharge-change-during-the-menstrual-cycle
Changes are driven by estrogen and progesterone fluctuations. Post-period: minimal, thick, sticky. Pre-ovulation: increasing, thinner, creamy as estrogen rises. Ovulation: peak discharge - clear, stretchy, egg-white consistency designed to help sperm. Luteal phase: thicker, stickier, decreasing as progesterone dominates. These changes support fertilization around ovulation and create a protective barrier during the luteal phase.

#### What does white discharge mean?
URL: https://femora.app/questions/what-does-white-discharge-mean
Normal: thin and smooth (common throughout cycle), thick and creamy (luteal phase, progesterone-related), thick and sticky (post-period). Concerning: cottage cheese-like with itching = likely yeast infection (affects 75% of women at least once), thin white-gray with fishy smell = possibly bacterial vaginosis. White discharge without other symptoms is normal.

#### What does yellow or green discharge mean?
URL: https://femora.app/questions/what-does-yellow-or-green-discharge-mean
Pale yellow can be normal (oxidized discharge). Bright yellow/yellow-green may indicate bacterial vaginosis, trichomoniasis (frothy, strong odor), or chlamydia/gonorrhea. Green discharge generally indicates active infection. See a doctor if accompanied by strong odor, itching, burning, pain during urination, or fever. Don't douche - it worsens infections.

#### What does brown discharge mean?
URL: https://femora.app/questions/what-does-brown-discharge-mean
Usually old oxidized blood - normal before/after periods, during ovulation spotting, with implantation bleeding (10–14 days after conception), or with hormonal birth control breakthrough bleeding. Less common causes: infections, cervical irritation, PCOS. See a doctor if it occurs frequently between periods without explanation, with pain/fever/odor, after menopause, or lasts longer than a few days.

#### Is discharge during ovulation normal?
URL: https://femora.app/questions/is-discharge-during-ovulation-normal
Yes - increased ovulation discharge is one of the body's most reliable ovulation signs. Characteristics: clear, stretchy (spinnbarkeit), slippery like raw egg whites, abundant. Caused by peak estrogen levels. This fertile mucus creates a sperm-friendly alkaline environment, helps sperm travel, and keeps sperm alive up to 5 days. The shift from wet/stretchy to dry/thick signals ovulation has passed.

#### When should I worry about discharge?
URL: https://femora.app/questions/when-should-i-worry-about-discharge
Warning signs: bright yellow/green/gray color, strong fishy odor (especially after sex), cottage cheese-like texture, frothy/foamy texture, itching/burning, redness/swelling, pain during urination or sex, pelvic pain, bleeding between periods. Common conditions: yeast infection (thick white clumpy + itching), BV (thin gray-white + fishy smell), trichomoniasis (yellow-green frothy + itching), chlamydia/gonorrhea (yellow/cloudy, may have no other symptoms). Seek urgent care for fever + abnormal discharge or severe pelvic pain.

#### Can stress affect vaginal discharge?
URL: https://femora.app/questions/can-stress-affect-vaginal-discharge
Yes. Stress releases cortisol which interferes with estrogen and progesterone, changing discharge patterns. Chronic stress weakens the immune system, allowing yeast infections and bacterial vaginosis. Stress can delay or prevent ovulation, shifting expected discharge patterns. All types of stress affect it: work/financial, relationship, major life changes, sleep deprivation, over-exercising, illness.

#### How can I maintain healthy vaginal hygiene?
URL: https://femora.app/questions/how-can-i-maintain-healthy-vaginal-hygiene
Key principle: the vagina is self-cleaning. Wash the vulva (external area) daily with warm water, optional mild unscented soap. Never wash inside the vagina or douche. Wear breathable cotton underwear, wipe front to back, change menstrual products regularly (pads 4–6hrs, tampons 4–8hrs max). Avoid: douches, vaginal deodorants/sprays, scented tampons/pads, scented wipes, DIY remedies. Eat probiotics, stay hydrated, limit sugar.

#### Is it normal to have discharge every day?
URL: https://femora.app/questions/is-it-normal-to-have-discharge-every-day
Yes, daily discharge is normal for reproductive-age people. The vagina continuously produces fluid for moisture, cleaning, and infection protection. Average 1–4 ml per day, varies through cycle (minimal post-period, peak at ovulation, moderate during luteal phase). Increases with hormonal birth control, pregnancy, arousal, exercise. Not normal if daily discharge is yellow/green/gray, has strong odor, or causes constant itching.

#### Can discharge be a sign of pregnancy?
URL: https://femora.app/questions/can-discharge-be-a-sign-of-pregnancy
Yes, increased discharge (leukorrhea) can be an early pregnancy sign - white/milky, thin, mild-smelling, more abundant than usual. Caused by rising estrogen, increased pelvic blood flow, protective function, and mucus plug formation. Implantation bleeding (light brown/pink spotting, 10–14 days after conception) can also occur. Not reliable alone - look for other signs: missed period, breast tenderness, fatigue, nausea. Test with first morning urine on or after expected period date.

### Vaginal Health & Infections

#### What causes vaginal itching and when should I see a doctor?
URL: https://femora.app/questions/what-causes-vaginal-itching
Vaginal itching is most often a yeast infection (intense itch, thick white discharge), irritants like scented products and douching, low estrogen, skin conditions, or sometimes BV or an STI. Stop scented/harsh products and switch to cotton first. See a doctor if itching comes with abnormal discharge or odor, doesn't settle in a few days, keeps returning, or involves sores or bleeding. Don't default to an OTC antifungal unless you know it's yeast.

#### What does vaginal odor mean? What's normal and what's not?
URL: https://femora.app/questions/what-does-vaginal-odor-mean
A mild, musky scent is normal and shifts slightly across the cycle and after sex/exercise. A strong fishy odor (especially after sex) usually means bacterial vaginosis; a foul smell with green, yellow, or frothy discharge can signal trichomoniasis or another STI; a yeasty smell with itching points to a yeast infection. Avoid douching (it worsens odor) and see a doctor for a strong, persistent odor or one with abnormal discharge.

#### What is vaginal pH and why does it matter?
URL: https://femora.app/questions/what-is-vaginal-ph
Vaginal pH measures acidity; healthy is slightly acidic at about 3.8–4.5, maintained by protective lactobacilli that prevent infection. pH rises (less acidic) with bacterial vaginosis, periods, semen, douching, and low estrogen. High pH is linked to BV, but pH test strips only flag that something is off, not what. Protect healthy pH by not douching and avoiding scented products.

#### Yeast infection vs bacterial vaginosis: how do I tell the difference?
URL: https://femora.app/questions/yeast-infection-vs-bacterial-vaginosis
Quick tell: yeast itches, BV smells. Yeast = thick white cottage-cheese discharge, intense itching, no odor, treated with antifungals. BV = thin gray discharge, strong fishy odor, little itching, treated with prescription antibiotics. OTC antifungals only treat yeast, so confirm before self-treating; the two can occur together. See a doctor if unsure, recurring, first-ever, or pregnant.

#### How does diet affect vaginal health?
URL: https://femora.app/questions/how-does-diet-affect-vaginal-health
Diet helps indirectly via blood sugar, immunity, and the microbiome. Fermented foods, fiber, hydration, and healthy fats may support balance; high sugar and uncontrolled blood sugar raise yeast-infection risk. No food cleans the vagina or cures an active infection, and probiotic supplements have mixed evidence, so diet is a supporting habit, not a treatment.

#### What are the signs your vaginal microbiome is out of balance?
URL: https://femora.app/questions/signs-vaginal-microbiome-out-of-balance
Signs of dysbiosis include a change in discharge, a new or fishy odor, itching or burning, recurrent BV or yeast, and discomfort during sex or urination - the key signal being a change from your own normal. Douching, scented products, antibiotics, hormonal shifts, and new partners can tip the balance. Fix it by avoiding douching, treating infections properly, and seeing a clinician for recurrent symptoms.

#### What does pink discharge mean?
URL: https://femora.app/questions/what-does-pink-discharge-mean
Pink discharge is light blood mixed with normal fluid, most often from ovulation spotting, the start/end of a period, implantation in early pregnancy, friction after sex, or starting hormonal birth control. See a doctor if it's new or repeated between periods, regularly follows sex, comes with pain, fever, or odor, occurs in pregnancy with cramping, or happens after menopause.

#### Why do I feel dry? What causes vaginal dryness?
URL: https://femora.app/questions/what-causes-vaginal-dryness
Vaginal dryness is usually from lower estrogen (perimenopause, menopause, after childbirth, breastfeeding), plus some medications, harsh scented products, insufficient arousal, and certain conditions. It's very treatable with vaginal moisturizers, lubricants, and prescription vaginal estrogen. See a doctor if it affects daily comfort or sex, or comes with itching, burning, or abnormal discharge.

#### What causes pain during sex?
URL: https://femora.app/questions/what-causes-pain-during-sex
Pain during sex (dyspareunia) is most often from vaginal dryness or low estrogen, but also infections, insufficient arousal, vaginismus, endometriosis, pelvic conditions, skin problems, or emotional factors. It's treatable with lubricants, vaginal estrogen, treating infections, more arousal, pelvic floor therapy, and addressing underlying conditions. See a doctor if pain is new, severe, persistent, deep, or comes with abnormal discharge or bleeding.

#### Can tight clothing affect vaginal health?
URL: https://femora.app/questions/can-tight-clothing-affect-vaginal-health
Tight, non-breathable clothing doesn't directly cause infections but traps heat and moisture that yeast and bacteria favor, raising risk if you're already prone. What sits nearest the skin matters most: wear breathable cotton underwear, change out of damp gym clothes and swimsuits promptly, and choose breathable fabrics if you get recurrent yeast or BV.

#### Are feminine washes necessary?
URL: https://femora.app/questions/are-feminine-washes-necessary
No. The vagina is self-cleaning, and scented washes, sprays, and douches strip protective bacteria and disrupt pH, raising the risk of BV and irritation. Wash only the vulva with warm water (a plain unscented cleanser is optional), never clean inside the vagina, and see a clinician for persistent odor, itching, or abnormal discharge rather than masking it.

#### Can swimming, workouts, or sweating cause vaginal infections?
URL: https://femora.app/questions/can-exercise-or-sweating-cause-infections
Exercise, swimming, and sweating don't directly cause infections, but staying in damp gym clothes or a wet swimsuit traps warmth and moisture that let yeast overgrow if you're prone. Change out of wet/sweaty clothing promptly, wear breathable cotton underwear, dry the area after heavy sweating, and avoid scented products and douching; see a clinician for recurrent infections.

#### How can I prevent recurring yeast infections?
URL: https://femora.app/questions/how-to-prevent-recurring-yeast-infections
Prevent recurring yeast infections with breathable cotton underwear, prompt changes out of damp clothing, no douching or scented products, and careful antibiotic use, while addressing triggers like uncontrolled blood sugar. If you get four or more a year, see a clinician to confirm it's really yeast, get a longer/maintenance antifungal plan, and check for underlying causes; probiotics have only mixed evidence.

#### UTI vs vaginal infection: what's the difference?
URL: https://femora.app/questions/uti-vs-vaginal-infection
A UTI affects the urinary system (burning when you urinate, urgency, cloudy urine, no discharge) and needs antibiotics; a vaginal infection affects the vagina (itching and discharge for yeast, fishy odor for BV). Quick rule: burning when you pee = UTI; itching, discharge, or odor = vaginal infection. See a doctor for UTI symptoms promptly or if unsure, since you can have both.

#### Can antibiotics affect vaginal health?
URL: https://femora.app/questions/can-antibiotics-affect-vaginal-health
Yes; antibiotics kill protective lactobacilli along with harmful bacteria, which is why yeast infections (and sometimes BV) often follow a course. Reduce risk by taking antibiotics only when needed, watching for early symptoms, and asking about a preventive antifungal if you're very prone. Post-antibiotic yeast infections are easily treated, and the microbiome usually recovers over time.

#### What underwear is best for vaginal health?
URL: https://femora.app/questions/best-underwear-for-vaginal-health
Breathable, moisture-wicking cotton is best because it keeps the area dry and less hospitable to yeast and bacteria, while synthetics trap heat and moisture. Change daily and after sweating or swimming, avoid tight non-breathable styles, and consider going underwear-free at night. Not douching and avoiding scented products matter even more than fabric choice.

## Prolactin in Women (August 2026)

Prolactin is a pituitary hormone held down by a dopamine brake rather than switched on by a signal, which is why dopamine-blocking medications raise it and dopamine-mimicking drugs treat it. In pregnancy it rises 10 to 20 times above baseline (roughly 80 to 400 ng/mL versus under about 25 ng/mL when not pregnant) to build the milk-producing tissue in the breasts, while placental progesterone blocks actual milk production - which is why milk comes in on days 2 to 3 after birth, once the placenta is delivered and progesterone crashes. Prolactin also suppresses kisspeptin and GnRH, the mechanism behind lactational amenorrhea. Outside pregnancy, high prolactin causes irregular or absent periods, galactorrhea, low libido, vaginal dryness, and infertility, with symptoms tracking the level: 20 to 50 ng/mL may only shorten the luteal phase, 50 to 100 makes periods infrequent, over 100 usually stops them, and over about 200 strongly suggests a prolactinoma. Common causes are medications (antipsychotics especially, plus metoclopramide, some antidepressants, verapamil, cimetidine, opioids), hypothyroidism (present in 20 to 40% of hypothyroid patients), a benign prolactinoma (up to 40% of clinically recognized pituitary adenomas), chest wall or nipple stimulation, and kidney disease, with about a third idiopathic. Because sleep, stress, pain, exercise, sex, and even a recent breast exam spike prolactin, a single mildly high result should be repeated before it is acted on; macroprolactin causes false highs in asymptomatic women and the hook effect can make a very large tumor read falsely low. Treatment addresses the cause first, and dopamine agonists (cabergoline first-line, bromocriptine preferred in pregnancy) normalize prolactin in 80 to 90% of cases while shrinking prolactinomas, with periods and fertility usually returning within weeks to a few months.
