In most cases, vaginal discharge is completely normal. It’s your body’s way of keeping the vagina clean and moist. Healthy discharge is typically clear, milky white, or off-white, and the average person produces between 1 and 3 milliliters per day. What matters is whether something has changed: a new color, a different texture, an unusual smell, or symptoms like itching or burning that accompany it.
What Normal Discharge Looks Like
Normal discharge varies more than most people realize. It can be watery, sticky, creamy, or thick depending on where you are in your menstrual cycle, and all of those textures are healthy. The color ranges from clear to white to slightly off-white or faintly yellow. It shouldn’t have a strong or unpleasant odor, though a mild scent is normal.
Your discharge changes throughout the month in a predictable pattern. In the days right after your period, it tends to be dry or tacky, often white or slightly yellow. As you move toward the middle of your cycle, it becomes creamier, wetter, and more cloudy. Right around ovulation (roughly days 10 to 14 of a 28-day cycle), discharge becomes slippery, stretchy, and clear, often compared to raw egg whites. After ovulation, it dries up again and stays that way until your next period.
Pregnancy increases discharge noticeably. The thin, milky white discharge that many pregnant people experience is called leukorrhea, and it’s driven by rising hormone levels. On the other end of the spectrum, menopause typically reduces discharge because of lower estrogen, which can leave the vaginal tissue thinner and drier.
What Different Colors Can Tell You
Color is one of the easiest ways to gauge whether your discharge is worth paying attention to.
- White: Usually normal. If it’s thick, clumpy (like cottage cheese), and comes with itching or a strong odor, it may point to a yeast infection.
- Gray: Gray discharge is a common sign of bacterial vaginosis (BV), especially when paired with a fishy smell. This is worth getting checked.
- Yellow: A very faint yellow tint, especially after a dietary change, is often harmless. A deeper yellow or yellowish-green color typically signals an infection, including sexually transmitted infections.
- Green: Green or yellow-green discharge usually indicates a bacterial or sexually transmitted infection and should be evaluated promptly.
- Pink: Most commonly seen as spotting before a period, after ovulation, or after sex that caused minor irritation. In early pregnancy, it can signal implantation bleeding.
- Brown or dark red: Often just old blood leaving the body at the tail end of a period or between cycles. A dark rust color is typical.
Common Infections That Change Discharge
Yeast Infections
A yeast infection produces thick, white discharge with a cottage cheese-like texture. It usually doesn’t smell strongly, but it comes with intense itching, redness, and sometimes burning during urination or sex. Yeast infections are caused by an overgrowth of fungus that normally lives in the vagina in small amounts, and they’re one of the most common reasons people notice a sudden change in discharge.
Bacterial Vaginosis
BV is the most common vaginal infection in people of reproductive age. Its hallmark is a thin, milky white or gray discharge with a noticeable fishy odor. The smell often gets stronger after sex. BV happens when the balance of bacteria in the vagina shifts, allowing certain types to multiply. It’s not sexually transmitted, but it does need treatment to clear up.
Sexually Transmitted Infections
Trichomoniasis, a common STI caused by a parasite, can produce a thin discharge that ranges from clear to white, yellowish, or greenish and often smells fishy. It also causes itching, burning, redness, and discomfort during urination. Gonorrhea and chlamydia can both cause abnormal discharge as well, though chlamydia in particular often produces no symptoms at all, which is why routine screening matters.
Discharge From the Penis
While most people searching this question are asking about vaginal discharge, penile discharge is a different situation. Outside of pre-ejaculate (the clear fluid that appears during arousal) and smegma (a white, waxy buildup under the foreskin that’s normal if painless), discharge from the penis is almost always a sign of infection. The most common culprits are gonorrhea, chlamydia, and non-specific urethritis, all of which can cause lasting problems like infertility if left untreated. Any unexpected discharge from the penis warrants a visit to a doctor or sexual health clinic.
Signs That Something Has Changed
The key word is “change.” You know your body’s baseline better than anyone. The signals worth paying attention to include a sudden shift in the amount, color, odor, or consistency of your discharge, especially when paired with other symptoms like itching, redness, swelling, burning during urination, or pelvic pain. A fever alongside unusual discharge is a more urgent sign, as it can indicate an infection that has spread beyond the vaginal canal.
If your symptoms appeared after unprotected sex or potential exposure to an STI, getting tested is important even if the discharge seems mild. Many STIs cause subtle changes that are easy to dismiss, and early treatment prevents complications. Symptoms that persist for more than a week despite basic hygiene measures, or blisters and sores on or around the genitals, also warrant prompt evaluation.
