Discharge is something everyone with a uterus experiences from puberty and throughout life. It can vary in amount, color, and consistency — and it can also change during different phases of the cycle or, for example, during pregnancy.

The consistency of discharge changes throughout the cycle and can tell you where you are. Whether it’s thin and watery, ‘stretchy’ and egg-white-like during ovulation, or almost dry, your discharge can show you what stage of the cycle you’re in.

Discharge is the body’s way of keeping the vagina clean and healthy. It flushes away dead cells, dirt, and bacteria, keeps the mucous membranes moist, and maintains a slightly acidic pH, which protects against infections. That’s why you don’t need to wash internally - the body takes care of it on its own.

Discharge contains lactic acid bacteria, which keep the pH low and the vagina healthy. This gives it the naturally slightly acidic smell and taste (and sometimes also stains on your underwear that don’t come out in the wash). The smell should not be unpleasant, but if it suddenly changes or becomes very strong, it’s a good idea to contact your doctor.

Discharge is a useful indicator of health. If the color, odor, consistency, or amount changes significantly, it could be a sign of infection or irritation. If you experience itching, burning, or pain, you should contact your doctor.
