Vaginal discharge can range from clear to white, yellow, green, gray, brown, pink, or even red. Clear, milky white, and off-white discharge is normal and healthy. Other colors often signal a shift in hormones, an infection, or old blood leaving the body. Understanding what each color typically means can help you recognize when something has changed and whether it matters.
Clear, White, and Off-White
These are the baseline colors of healthy discharge. Your body produces this fluid continuously to keep the vagina clean, lubricated, and protected from infection. The thickness changes throughout your menstrual cycle. Around ovulation, discharge often becomes extra slippery and wet, sometimes resembling raw egg whites. In the days before and after your period, it may be thicker and more opaque.
During pregnancy, the volume of discharge increases noticeably. This is called leukorrhea, and it’s typically thin, clear, or milky white without an unpleasant smell. The extra fluid helps block infections from traveling up toward the uterus. As long as it stays in that color range and doesn’t itch or burn, it’s a normal part of pregnancy.
Thick White Discharge
White discharge on its own is normal, but the texture matters. A thick, clumpy discharge that looks like cottage cheese is the hallmark of a yeast infection. It’s usually white, can be watery or dense, and often has no strong odor. What sets a yeast infection apart from normal discharge is the accompanying symptoms: intense itching, redness, and soreness around the vulva and vagina. Yeast infections are extremely common and are caused by an overgrowth of fungus that naturally lives in the vaginal area.
Yellow and Green
Yellow or green discharge is one of the more noticeable color shifts, and it usually points to an infection. Trichomoniasis, a sexually transmitted infection caused by a parasite, produces thin or frothy discharge that can be clear, white, yellow, or green and carries a foul smell. Other symptoms include genital burning, soreness, itching, and pain during urination or sex. Some people also feel a dull ache in the lower abdomen.
Gonorrhea and chlamydia can also produce yellowish or greenish discharge, though these infections sometimes cause no symptoms at all. If your discharge turns yellow or green, especially with an odor, itching, or pelvic pain, that combination is worth getting checked. During pregnancy, yellow or green discharge is considered a warning sign of possible vaginal infection.
Gray
A thin, grayish-white discharge with a strong fishy smell is the classic presentation of bacterial vaginosis (BV). BV happens when the normal balance of bacteria in the vagina gets disrupted, allowing certain species to overgrow. The discharge tends to be homogeneous and milklike in consistency, coating the vaginal walls smoothly rather than appearing clumpy. The fishy odor is often more noticeable after sex.
BV is the most common vaginal condition in women of reproductive age, and it’s not a sexually transmitted infection, though sexual activity can trigger it. It sometimes clears on its own, but persistent cases are typically treated with antibiotics.
Brown and Dark Red
Brown discharge is almost always old blood. Blood turns brown as it oxidizes, so when it takes a while to leave the body, it darkens. This is why you might notice brown spotting a day or two before your period starts or in the final days as it tapers off. That old blood can start making its way out one to two weeks before your next period begins.
Brown spotting between periods has several common causes. Ovulation can trigger light bleeding about 10 to 16 days after the first day of your last period. When estrogen levels drop after the egg is released, the hormonal dip can produce a small amount of spotting. Hormonal birth control is another frequent cause. Breakthrough bleeding is especially common in the first three to six months after starting a new method, particularly estrogen-free options like certain pills, hormonal IUDs, or injectable contraceptives. Missing a few doses of birth control pills can also trigger brown spotting.
Pink
Pink discharge is fresh blood mixed with normal vaginal fluid, diluting the red color. It commonly appears at the very beginning or end of a period, during ovulation spotting, or after sex if there’s minor irritation to the cervix or vaginal walls. Light pink spotting can also occur in very early pregnancy when a fertilized egg implants in the uterine lining, though not everyone experiences this.
Changes After Menopause
After menopause, declining estrogen levels cause the vaginal walls to become thinner and drier, a condition called vaginal atrophy. Discharge in this stage of life often looks different from what you may have been used to. It can become thin, watery, sticky, and yellow or gray in color. Because the vaginal tissue is more fragile, minor irritation or inflammation can also cause pink or slightly bloody discharge. A noticeable change in color, consistency, or volume after menopause is worth mentioning to your healthcare provider, since the same symptoms can overlap with infections or other conditions.
Color at a Glance
- Clear to milky white: Normal, healthy discharge that shifts in thickness with your cycle
- Thick, clumpy white: Likely a yeast infection, especially with itching and redness
- Yellow or green: Often signals an infection like trichomoniasis, gonorrhea, or chlamydia
- Gray: Characteristic of bacterial vaginosis, typically with a fishy odor
- Brown: Old blood leaving the body, common around periods, ovulation, or with hormonal birth control
- Pink: Small amounts of fresh blood mixed with discharge, often from ovulation, early periods, or minor irritation
- Red: Active bleeding, normal during menstruation but worth investigating at other times
Color alone doesn’t tell the full story. Odor, texture, volume, and accompanying symptoms like itching, burning, or pelvic pain all matter. A temporary shift in color around ovulation or your period is usually nothing to worry about. A persistent change, especially combined with a strong smell or discomfort, points to something your body is responding to.
