Vaginal Discharge: What Is Normal and When Should You See a Doctor?
Color, consistency and smell — a practical guide to what your body is telling you
Quick answer: Normal vaginal discharge is clear to white, has a mild or no smell and changes through your cycle. See a doctor if discharge becomes yellow, green or gray, thick like cottage cheese, frothy, fishy-smelling or comes with itching, burning, pain or bleeding — signs of infections such as BV, yeast or an STI.
Vaginal discharge is a normal, healthy part of how the body keeps the vagina clean and protected. Its amount and texture change throughout the menstrual cycle. Knowing what's normal for you makes it easier to notice when something has changed.
What Normal Discharge Looks Like
- Clear, white or slightly off-white
- Thin and watery, or thicker and creamy, depending on your cycle
- Clear and stretchy, like egg white, around ovulation
- A mild smell or no smell
Discharge often increases around ovulation, during pregnancy, with sexual arousal and when using hormonal contraception.
Changes That May Signal a Problem
- Thick, white, cottage-cheese-like discharge with itching: often a yeast infection.
- Thin, gray or white discharge with a fishy smell: often bacterial vaginosis(BV).
- Yellow-green, frothy discharge: may be trichomoniasis.
- Yellow or cloudy discharge with pelvic pain or bleeding: may be chlamydia or gonorrhea.
- Brown or bloody discharge outside your period: should be checked if it persists.
When to See a Doctor
- A change in color, smell or consistency that lasts more than a few days
- Itching, burning, redness or swelling
- Pelvic pain, fever or pain during sex
- Bleeding between periods or after sex
- You think you may have been exposed to an STI
How Doctors Diagnose the Cause
An OB-GYN can examine you and take a quick swab. Tests may check for yeast, BV, trichomoniasis and other STIs. Results for some tests are available quickly, so treatment can often start the same day.
Everyday Tips
- Avoid douching — it disrupts healthy vaginal bacteria.
- Wear breathable cotton underwear.
- Use mild, unscented products.
