Vaginal odor. tried both prescription previously given for bv &over the counter yeast infection medicine. neither resolved the smell. what could it be?

Don't know: Bacterial vaginosis can cause a “fishy” smell. Other possibilities include STD’s like Gonorrhea, Trichomoniasis & Chlamydia or pelvic inflammatory disease. If there is a retained tampon or a lack of proper vaginal hygiene those are potential causes. Yeast is usually odorless but is still a possibility. If a woman has a fistula or cancer that can also lead to odor. See your doctor if uncertain.
