Vaginal Discharge: What's Normal and When It Signals a Problem
Normal vaginal discharge is clear, white or off-white, has little or no smell, and changes in amount and texture through your menstrual cycle. It's how the vagina cleans itself and stays healthy. A change in color, smell or texture, especially with itching, burning or pain, can signal an infection that needs treatment.
Yes, everyone wonders about this, and yes, everyone has discharge every day. The goal isn't to have none. It's to know your own normal so you notice when something changes.
What normal looks like
Healthy discharge is fluid and cells from the cervix and vaginal walls, plus the good bacteria that keep the vagina slightly acidic. It's usually:
- Clear, white or off-white
- Mild in odor, or odorless
- Thin and watery, or thick and creamy, depending on the time of month
- Slightly yellow once it dries on underwear (that faint yellow or bleached patch in your underwear is from the acidity, and it's normal)
Your cycle, in discharge
| Time in cycle | What discharge is usually like |
|---|---|
| Right after your period | Little discharge, may feel dry |
| Approaching ovulation | More, cloudy or white, slightly sticky |
| Around ovulation | Clear, slippery and stretchy, like raw egg whites |
| After ovulation | Thicker, creamier, less of it |
| Just before your period | May increase or turn cloudy |
It also normally increases with pregnancy (thin and milky), sexual arousal, exercise, and sometimes hormonal birth control. After menopause it usually decreases, and dryness becomes more common.
About smell: a mild musky or slightly sour scent is normal. The vagina is naturally acidic, and its scent shifts with your cycle, sweat and sex. A strong fishy smell, a rotten odor, or any smell plus itching, burning or a color change isn't typical.
The color guide
| What you notice | Possible cause |
|---|---|
| Clear or white, no odor, no symptoms | Usually normal |
| Thin gray or white with a fishy odor, especially after sex | Bacterial vaginosis (BV) |
| Thick, white, clumpy like cottage cheese, with itching or burning | Yeast infection |
| Yellow-green, frothy, with odor and itching | Trichomoniasis |
| Yellow, green or cloudy, sometimes with pelvic pain or bleeding | Chlamydia or gonorrhea, though these often cause no symptoms |
| Brown or pink | Old blood at the start or end of a period, or spotting; check with a clinician if it happens often, after sex, during pregnancy or after menopause |
| Strong foul odor with discharge | Possibly a forgotten tampon or other retained object |
A word of caution: color alone can't diagnose anything. Symptoms overlap a lot, and testing is the only reliable way to know. Some infections, like chlamydia, often cause no change at all; see chlamydia symptoms in women.
On the forgotten tampon: it's more common than people think, and it's nothing to be embarrassed about. If you can't reach it, a clinician can remove it in a minute, and they've done it many times before.
Brown discharge is usually old blood. It's common right before or after a period, around ovulation for some people, after starting a new hormonal birth control, or after a pelvic exam or sex. Get it checked if it happens often between periods, after sex, during pregnancy, or at any time after menopause.
What causes abnormal discharge
Common vaginal infections
- Bacterial vaginosis (BV): an imbalance of normal vaginal bacteria. The CDC calls it the most common vaginal condition in women ages 15 to 44. It's not an STI, though sex can trigger it.
- Yeast infection: an overgrowth of Candida, often after antibiotics, during pregnancy, or with uncontrolled diabetes.
- Trichomoniasis: a common, curable STI caused by a parasite.
Sexually transmitted infections
Chlamydia and gonorrhea can cause discharge, but often cause nothing at all. Untreated, they can lead to pelvic inflammatory disease and fertility problems. Where to get tested: STI testing in NYC.
Other causes
- Irritation from soaps, douches, scented products or spermicides
- A forgotten tampon
- Cervical inflammation
- Low estrogen after menopause, which can cause thin, watery or yellowish discharge with irritation
- Less commonly, cervical or other gynecologic conditions, which is why persistent abnormal discharge or bleeding should be checked
Myth vs. fact
Myth: Discharge means you're not clean. Fact: Discharge is how the vagina keeps itself clean.
Myth: Douching keeps things fresh. Fact: ACOG advises against douching. It disrupts healthy bacteria and is linked to infections.
Myth: Itching always means yeast. Fact: Many people who think they have a yeast infection actually have BV, trich or irritation. Over-the-counter yeast treatments won't help those. If you've treated yourself and it's back, or it never fully cleared, get tested.
Keeping things healthy
- Skip scented products: sprays, wipes, perfumed pads, bubble baths.
- Wash the vulva with warm water, and mild unscented soap on the outside only if you want.
- Wear breathable cotton underwear and change out of wet gym clothes or swimsuits promptly.
- Use condoms to lower STI risk.
What happens at the appointment
Your clinician may:
- Ask about your symptoms, cycle, sexual history and products you use
- Do a pelvic exam
- Check vaginal pH and look at a sample under a microscope
- Send swabs for BV, yeast, trichomoniasis, chlamydia and gonorrhea
Some results are ready during the visit; lab results often come back within a few days. Treatment depends on the cause. Tip: try not to use vaginal creams or have sex for a day or two before the visit if you can, because both can make results harder to read.
During pregnancy
More thin, white or milky discharge (leukorrhea) is normal in pregnancy. Call your prenatal provider if you notice:
- A sudden gush or a steady trickle of watery fluid, which could be amniotic fluid
- Bleeding or brown discharge
- An increase in mucus-like, watery or bloody discharge before 37 weeks, which can be a sign of preterm labor
- Itching, odor or a change in color
Don't treat a suspected infection yourself during pregnancy. Some treatments aren't recommended in pregnancy, and BV has been linked to preterm birth.
After menopause
With lower estrogen, vaginal tissue thins and discharge usually decreases. Some people notice dryness, irritation, or a thin yellowish discharge. This is often part of genitourinary syndrome of menopause, and it's treatable. Any bleeding, or pink or brown discharge, after menopause should always be checked.
When to see a doctor
Call your gynecologist or women's health provider if you have:
- Discharge with a fishy or foul odor
- Gray, green, yellow or frothy discharge
- Itching, burning, swelling or redness of the vulva
- Pain when you pee or during sex
- Pelvic or belly pain, or fever
- Bleeding between periods, after sex, or after menopause
- A possible STI exposure or a new partner
- Symptoms that come back after treatment
- Any unusual discharge during pregnancy

Yes. Daily discharge is normal and is how the vagina keeps itself clean and healthy. The amount varies from person to person and throughout the month.
What color discharge is a sign of infection?
Gray discharge with a fishy smell often points to bacterial vaginosis, yellow-green frothy discharge can mean trichomoniasis, and thick white discharge with itching often means a yeast infection. Yellow or green discharge can also be a sign of chlamydia or gonorrhea.
