Vaginal discharge is most often a normal and regular occurrence. However, there are certain types of discharge that can indicate an infection. Abnormal discharge may be yellow or green, chunky in consistency, or have a foul odor.
Vaginal discharge serves an important housekeeping function in the female reproductive system. Fluid made by glands inside the vagina and cervix carries away dead cells and bacteria. This keeps the vagina clean and helps prevent infection.
