The white, creamy fluid that comes from the vagina is called vaginal discharge, and it’s completely normal. It’s made up of fluid from the vaginal walls, shed skin cells, and beneficial bacteria. Every woman of reproductive age produces it. The consistency, amount, and color shift throughout the menstrual cycle, during pregnancy, and during sexual arousal.
What Discharge Is Made Of
Vaginal discharge is a mix of several things your body produces naturally. It contains shed cells from the vaginal lining, a fluid that seeps through the vaginal walls, and secretions from glands near the cervix and vaginal opening. The fluid also carries lactobacilli, a type of beneficial bacteria that keeps the vagina slightly acidic, with a pH typically between 3.8 and 4.5. That acidity is what prevents harmful bacteria and yeast from taking over.
Discharge isn’t waste or a sign that something is wrong. It actively cleans the vaginal canal by flushing out old cells and maintaining a healthy bacterial balance. Think of it as a built-in self-cleaning system. The amount varies from person to person, but most women produce about a teaspoon per day.
How It Changes Throughout Your Cycle
If you’ve noticed the texture or color of this fluid changing from week to week, that’s hormones at work. On a typical 28-day cycle, discharge follows a predictable pattern:
- Days 1 to 4 (after your period): 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. This is often the “white cream” many people notice.
- Days 10 to 14 (around ovulation): Clear, stretchy, and slippery, resembling raw egg whites. This signals peak fertility.
- Days 15 to 28: Gradually dries up and becomes minimal until your next period.
The creamy, white phase is most prominent in the days before and after ovulation. Progesterone, the hormone that dominates the second half of your cycle, tends to make discharge thicker and whiter. Estrogen, which rises before ovulation, thins it out and makes it clear and stretchy.
Discharge During Sexual Arousal
The fluid produced during sexual arousal is different from regular daily discharge, though they can look similar. When you become aroused, blood flow to the vaginal walls increases, and this causes a clear, slippery lubricant to seep through the tissue. Production ramps up through the stages of arousal and tapers off after orgasm. This arousal fluid is typically thinner and more watery than the creamy white discharge you see on underwear during the day.
Some women also produce a separate clear fluid from small glands near the urethra during orgasm. This is distinct from both arousal lubrication and regular discharge.
Discharge During Pregnancy
Pregnant women often notice a significant increase in white or milky discharge, sometimes called leukorrhea. Higher estrogen levels and increased blood flow to the pelvic area drive this change. The extra discharge serves an important purpose: it helps prevent infections from traveling up toward the uterus. A steady, mild, white or clear discharge during pregnancy is normal and expected.
When the Color or Texture Signals a Problem
Normal discharge is white, off-white, or clear, with little to no odor. Certain changes in appearance, smell, or accompanying symptoms point to an infection.
Yeast infection: The discharge becomes thick, white, and clumpy, often compared to cottage cheese. It may be watery and typically has no strong smell. The telltale sign is itching and redness of the vulva and vagina. Yeast infections don’t change your vaginal pH, which is why they can develop even when your bacterial balance is otherwise fine.
Bacterial vaginosis (BV): The discharge turns thin, grayish-white, and homogeneous, with a noticeable fishy odor that often gets stronger after sex. BV happens when beneficial lactobacilli are replaced by other bacteria, pushing the vaginal pH above 4.5. It’s the most common vaginal infection in women of reproductive age.
Trichomoniasis: This sexually transmitted infection produces a frothy, yellow-green discharge with a strong odor. The vaginal pH rises significantly, often above 5.0. Itching, burning, and redness are common.
A good rule of thumb: if your discharge changes dramatically in color (green, gray, bright yellow), develops a strong or foul smell, or comes with itching, burning, or pain, something beyond normal hormonal fluctuation is going on.
What You Don’t Need to Do About Normal Discharge
Because discharge is a healthy function, it doesn’t need to be eliminated or reduced. Douching disrupts the natural bacterial balance and acidic pH that keep infections away. Scented soaps, sprays, and wipes applied internally can do the same. Warm water on the external area is all you need for hygiene. Wearing cotton underwear and avoiding prolonged time in damp clothing can help you feel more comfortable if the amount bothers you, but the discharge itself is your body working exactly as designed.
