Bacterial Vaginosis

Symptoms

The main symptom of bacterial vaginosis (BV) is an abnormal, foul-smelling vaginal discharge. Some women describe it as a fish-like odor that is most noticeable after having sex.

Other symptoms may include: 

• Thin vaginal discharge, usually white or gray in color 
• Pain during urination 
• Itching around the vagina

Some women who have signs of BV, such as increased levels of certain harmful bacteria, have no symptoms. A healthcare provider who sees these signs during a physical examination can confirm the diagnosis by doing lab tests of vaginal fluid.
