Definition
By Mayo Clinic staffMost vaginal discharge is completely normal. However, if your vaginal discharge has an unusual odor and appearance, or is accompanied by itching or pain, it may be a sign that something's wrong.
Vaginal discharge is a combination of fluid and cells that are continuously shed through your vagina. The function of vaginal discharge is to clean and protect the vagina. The color and consistency of vaginal discharge vary from whitish and sticky to clear and watery between your menstrual periods, roughly corresponding to the stage of your reproductive cycle. It's also normal to have some vaginal discharge during pregnancy.
Although most causes of abnormal vaginal discharge, including yeast infection, bacterial vaginosis and menopausal symptoms, are relatively harmless, they can be extremely uncomfortable. An abnormal vaginal discharge may also accompany certain sexually transmitted infections, some of which can spread to the uterus, ovaries and fallopian tubes. Rarely, far advanced cervical cancer could produce a brownish or blood-tinged vaginal discharge.
