Vaginal discharge is a fluid your body naturally produces to keep your vagina moist, clean, and protected from infection. It’s a mixture of cells, mucus, sweat, oils, and bacteria that lines the vaginal walls and flows out gradually throughout the day. Every woman and person with a vagina produces it, and in most cases, it’s a sign that your body is working exactly as it should.
Normal discharge is slightly acidic, with a pH between 3.8 and 4.5. That acidity acts like a built-in defense system, creating an environment where harmful bacteria struggle to survive. Healthy discharge doesn’t have a strong or offensive smell and shouldn’t cause itching, burning, or irritation.
What Normal Discharge Looks and Feels Like
Healthy discharge can range from clear to white or slightly yellowish. Its texture varies from thin and watery to slightly thick and creamy. The amount differs from person to person, and it also changes depending on where you are in your menstrual cycle, whether you’re pregnant, how hydrated you are, and even your level of arousal. Some days you’ll notice more on your underwear than others, and that’s completely typical.
You might also notice brown discharge for a day or two after your period ends. This is simply older blood that took longer to leave your uterus. When blood sits in the body longer, it oxidizes (reacts with air) and turns from red to brown. It can look thicker, drier, or clumpier than fresh menstrual blood. For some women this lasts a day, for others it comes and goes for a week or two, depending on how quickly the uterine lining sheds.
How Discharge Changes Throughout Your Cycle
If you pay attention over the course of a month, you’ll notice a predictable pattern. On a typical 28-day cycle, the changes look roughly like this:
- Right after your period (days 1 to 4): Dry or tacky, usually white or slightly yellow.
- Days 4 to 6: Sticky and slightly damp, white in color.
- Days 7 to 9: Creamy with a yogurt-like consistency, wet and cloudy.
- Around ovulation (days 10 to 14): Stretchy, slippery, and clear, resembling raw egg whites. This is your most fertile window. The wet, slippery texture helps sperm travel through the vagina and into the uterus.
- After ovulation (days 15 to 28): Gradually dries up and becomes minimal until your next period starts.
These shifts are driven by hormones. Estrogen rises before ovulation, producing that wet, stretchy mucus. After ovulation, progesterone takes over, and discharge dries up significantly. Not everyone follows this exact timeline, but the general pattern of wet-then-dry holds true for most cycles.
Discharge During Pregnancy and Menopause
Early in pregnancy, many women notice a slight increase in discharge. This pregnancy-related discharge is called leukorrhea. It’s thin, clear or milky white, and has little to no smell. It looks similar to everyday discharge, just more of it. The increase happens because hormone levels rise sharply and blood flow to the vaginal area increases.
At the other end of the spectrum, menopause brings the opposite change. As estrogen levels drop, the vaginal lining becomes thinner, drier, and less elastic. Discharge decreases noticeably, and many women experience vaginal dryness as a result. Some women going through menopause notice a yellowish discharge, which can be related to thinning vaginal tissue rather than infection. Your vaginal pH also shifts higher (less acidic) after menopause, which can make you more susceptible to infections.
Signs That Something Is Off
Most vaginal infections cause noticeable changes in discharge. The two most common culprits are bacterial vaginosis (BV) and yeast infections, and they look quite different from each other.
BV produces a thin, grayish discharge that tends to be heavier than usual. The hallmark is a fishy smell, often more noticeable after your period or after sex. A yeast infection, on the other hand, causes thick, white, lumpy discharge that looks like cottage cheese. It typically comes with intense itching and irritation but less odor.
Sexually transmitted infections can also change your discharge. Trichomoniasis, a common STI caused by a parasite, produces a yellowish or greenish discharge that may be thin or frothy, often with a fishy smell. Chlamydia and gonorrhea can cause increased or unusual discharge as well, sometimes accompanied by pelvic pain or bleeding between periods.
In general, these changes are worth paying attention to:
- Color shifts: Green, gray, or bright yellow discharge
- Texture changes: Cottage cheese-like clumps or frothy, foamy fluid
- Smell: A strong fishy or foul odor that’s new for you
- Accompanying symptoms: Itching, burning, irritation, pelvic pain, or sores
What Can Disrupt Healthy Discharge
Your vagina is self-cleaning, and most of what it needs to stay healthy, it handles on its own. The biggest mistakes tend to involve adding products that interfere with that process.
Douching is the most well-studied example. It strips away the normal bacteria that protect against infection and disrupts the vagina’s natural acidity. Women who douche weekly are five times more likely to develop BV than women who don’t. If you already have an infection, douching can push bacteria upward into the uterus and fallopian tubes, potentially causing pelvic inflammatory disease, a serious condition that can affect fertility.
Scented tampons, pads, powders, and sprays carry similar risks. They can irritate the delicate vaginal tissue and throw off the balance of bacteria that keeps your discharge healthy and your pH in the right range. Plain, unscented products are a safer choice. Washing the external vulva with warm water, or at most a mild unscented soap, is all that’s needed to stay clean. The inside of the vagina doesn’t need any help.
