Having discharge is completely normal. The vagina produces fluid every day to keep itself clean, moist, and protected from infection. Healthy discharge is clear, milky white, or off-white, and its texture can range from watery to thick and pasty depending on where you are in your menstrual cycle. What matters is not whether you have discharge, but whether it has changed in color, smell, texture, or amount in a way that’s new for you.
What Normal Discharge Looks Like
Normal vaginal discharge is your body’s self-cleaning system at work. It carries away dead cells and bacteria, keeping the vaginal environment balanced. Everyone produces different amounts, and there’s no “right” volume. Some people notice it on their underwear daily, while others barely see it.
The color should be somewhere in the range of clear to white. The consistency shifts throughout the month based on your hormone levels. Right after your period, you may have very little discharge. As ovulation approaches, it becomes wetter, stretchier, and slippery, often compared to raw egg whites. You’ll typically notice this egg-white consistency for about three or four days around ovulation. After ovulation, it usually thickens again and becomes more pasty or creamy. These shifts are driven by estrogen and progesterone and are a sign that your reproductive system is functioning as expected.
Pregnancy, Birth Control, and Other Factors
Pregnancy increases discharge noticeably. The sticky, clear or white fluid that shows up (sometimes called leukorrhea) is a normal response to the hormonal surge of pregnancy, especially in the second trimester. It’s your body’s way of protecting the birth canal from infection. As long as it stays clear or white and doesn’t have a strong odor, it’s not a concern.
Birth control pills can also affect how much discharge you produce because they alter your hormone levels. Starting or stopping hormonal contraception often changes what you see day to day.
Signs of a Yeast Infection
If your discharge is thick, white, and clumpy, looking similar to cottage cheese, a yeast infection is the most likely cause. Other signs include itching or burning in or around the vagina, redness and swelling of the vulva, and sometimes small cuts or cracks in the skin. Yeast infections are caused by an overgrowth of fungus that normally lives in the vagina in small amounts. They’re extremely common and typically treated with antifungal medication, either over the counter or prescribed.
Bacterial Vaginosis
Bacterial vaginosis (BV) happens when the balance of bacteria in the vagina shifts, allowing certain types to multiply too much. The hallmark symptom is a thin, milky discharge with a noticeable fishy smell. The odor is often stronger after sex. BV is the most common vaginal infection in people of reproductive age, and it’s not sexually transmitted, though sexual activity can increase the risk.
If you visit a clinic, a provider can diagnose BV by examining a small sample of discharge under a microscope, checking the acidity of the fluid, or doing a “whiff test” where the sample is mixed with a chemical to see if it produces that fishy odor. Treatment is straightforward with a course of antibiotics.
STI-Related Discharge
Certain sexually transmitted infections change the color, texture, and smell of discharge in distinctive ways. Trichomoniasis, a common and treatable STI, can produce a yellowish or greenish discharge that’s thin or frothy and often has a fishy smell. You may also notice itching, burning, redness, or discomfort when you pee. Chlamydia and gonorrhea can cause increased discharge as well, sometimes yellow or cloudy, though many people with these infections have no obvious symptoms at all, which is part of what makes them so easily spread.
If your discharge has turned green, yellow, grey, or has a strong unpleasant smell that’s new for you, getting tested is the clearest path to an answer. Most STI testing involves a simple swab or urine sample.
Discharge in Men
Discharge from the penis is not normal in the way vaginal discharge is. Any fluid leaking from the tip of the penis, whether it’s cloudy, white, yellow, or contains blood, typically signals an infection of the urethra (the tube you urinate through). Gonorrhea is a well-known cause, with roughly 600,000 new cases per year in the U.S. But non-gonococcal urethritis is even more common, at about 3 million cases annually, and can be caused by chlamydia, trichomoniasis, genital herpes, or even physical irritation from things like vigorous cycling, spermicides, or scented soaps. If you notice penile discharge, it’s worth getting tested promptly since most causes are easily treated but can lead to complications if ignored.
Changes After Menopause
After menopause, estrogen levels drop significantly. This causes the vaginal lining to become thinner, drier, and less stretchy, a condition called vaginal atrophy. The first sign most people notice is dryness, especially during sex. The amount of normal vaginal fluid decreases, and the acid balance of the vagina shifts, which can make infections more likely. Some people with vaginal atrophy notice an unusual yellowish discharge. If dryness or discomfort is affecting your quality of life, treatments that restore moisture or address the estrogen decline are available.
When Discharge Is Telling You Something
The key question is always whether something has changed. You know your own baseline. Pay attention if your discharge shifts in color (green, yellow, grey, or blood-tinged), develops a foul or fishy smell, becomes frothy or cottage-cheese-like, or comes with new symptoms like pelvic pain, itching, burning during urination, bleeding between periods, bleeding after sex, or blisters and sores. Any of these combinations points to an infection or condition that benefits from diagnosis and treatment.
At a clinic, testing is usually quick and noninvasive. A provider may take a swab of the discharge and examine it under a microscope, check the pH, or send it for a more detailed lab test. Results often come back the same day or within a few days, and most causes of abnormal discharge respond well to treatment once identified.
