Vaginal odor is any odor that originates from the vagina. It's normal for your vagina to have a slight odor. But, a strong vaginal odor — for instance, a "fishy" smell — might be abnormal and could indicate a problem. Abnormal vaginal odor that happens because of infection or another problem is usually associated with other vaginal signs and symptoms such as itching, burning, irritation or discharge.
