What healthy discharge looks like
Vaginal discharge changes every day - it's how your reproductive tract keeps itself balanced. Estrogen rises through the first half of your cycle, peaks around ovulation, then drops; progesterone takes over in the second half. Each shift changes how much fluid is produced and what it looks like. There's a wide range of normal.
What your discharge color means
Color is the fastest clue, though texture, smell, and where you are in your cycle all matter too. Here is a quick read on the most common colors:
- Clear and stretchy: your most fertile sign, typical around ovulation. Clear and watery is also normal.
- White or creamy: usually normal, especially in the second half of your cycle. Thick, clumpy, cottage-cheese white with itching points to a yeast infection.
- Yellow: pale yellow can be normal; bright or thick yellow, or yellow with an odor or itching, can signal an infection.
- Green: not typical - green or yellow-green, often frothy, usually means an infection such as trichomoniasis and should be checked.
- Brown: almost always old blood, common at the start or end of a period or as light spotting.
- Pink: a little blood mixed in - can appear around ovulation, before a period, with implantation in early pregnancy, or after sex.
- Gray: often bacterial vaginosis, especially with a fishy smell - worth a clinician visit.
When to act
The patterns that warrant a doctor visit are: gray or fishy-smelling (BV), green or frothy (trich), persistent itchy cottage cheese (resistant yeast), any postmenopausal bleeding, and anything with pelvic pain or fever. For cycle-tracking context, see the menstrual cycle calculator; for fertility-related mucus, the cervical mucus guide is more specific; and for the meaning of period blood shades (brown, pink, dark red), see the period blood color guide.

Frequently asked questions
How does discharge change across the cycle?
Right after your period: dry or sticky. Mid-follicular: creamy. Around ovulation: clear, stretchy, egg-white (this is your most fertile sign). Luteal phase: thicker and stickier as progesterone rises. Just before your period: can be brown or pink as it mixes with old blood.
What does green discharge mean?
Green discharge is not typical and usually points to an infection. Green or yellow-green frothy discharge is often trichomoniasis (a common, treatable STI), and green discharge can also occur with bacterial vaginosis or, less often, gonorrhea or chlamydia. Green discharge - especially with a smell, itching, or pelvic pain - should be checked by a clinician, who can test and prescribe the right treatment.
Is yellow discharge normal?
It depends on the shade. Pale or light-yellow discharge that dries on your underwear can be normal, especially near your period or in early pregnancy. Bright yellow or yellow-green discharge, or yellow discharge with a strong odor, itching, or thick texture, more often signals an infection (BV, trich, or an STI) and is worth getting checked.
What does brown discharge mean?
Brown discharge is almost always old blood leaving the body slowly, which oxidizes and turns brown. It's most common at the very start or end of a period, or as light spotting mid-cycle. It can also appear around ovulation or as early-pregnancy spotting. Persistent brown discharge, or brown discharge with pain or a bad smell, is worth a check.
When should I see a doctor about discharge?
Gray or strong fishy-smelling discharge (often bacterial vaginosis), green or frothy discharge (often trichomoniasis), itchy white cottage-cheese discharge that doesn't clear with OTC antifungal (yeast infection that needs prescription strength), or any unusual discharge with pelvic pain, fever, or bleeding outside your period.
How is postpartum or postmenopausal discharge different?
Postpartum lochia is heavy at first and tapers from red to brown to yellow-white over weeks - normal. Postmenopausal discharge or any bleeding always warrants a check, even when it turns out to be benign atrophic vaginitis.
