See a doctor: This could be an infection and you should be seen.

Many causes: Vaginal discharge requires an examination to determine the cause and treatment. Bacterial vaginosis is the most common cause and often has a vaginal odor. Vaginal itching can be a sign of a yeast infection. Sometimes vaginal discharge can be a sign of a sexual transmitted infection. Sores can indicate herpes. Testing is important to determine the treatment and keep you and your partner safe.
