Normal vaginal discharge is mainly composed of mucus secreted by glands in the cervix and vagina, explains Mary Jane Minkin, MD, co author of A Woman’s Guide to Sexual Health and clinical professor of ob-gyn at Yale University School of Medicine. “it also contains some fluid produced by the vaginal walls as well as dead cervical cells that have slaughed off naturally,” say,” Dr. Minkin.
This mixture should be whitish to clear to pale yellow, depending on where you are in your cycle. Dark yellow or green fluid is often a sign of infection. On average, a woman emits about one to two teaspoons a day. Any sudden increase may mean something’s amiss.
