Vaginal discharge is a fluid or semisolid substance that is normal and helps keep the vagina clean. Normal vaginal discharge is clear or milky white and does not have an unpleasant odor. Bacterial vaginosis, yeast infections, or sexually transmitted diseases (STDs) including trichomonas, gonorrhea, or Chlamydia can cause a change in color or odor. Symptoms of infection may include
- yellow-green or gray discharge,
- strong odor, or
- irritation of the genitals.
Treatment depends on the infection.
