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.
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.
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.
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.
