DefinitionBy Mayo Clinic staff
Vaginal discharge is a combination of fluid and cells continuously shed through your vagina. Vaginal discharge functions 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.
Some amount of vaginal discharge is completely normal. However, if your vaginal discharge has an unusual odor and appearance, or occurs along with itching or pain, it may be a sign that something's wrong.
