Bacterial vaginosis?: The most common cause of strong vaginal odor is bacterial vaginosis, an overgrowth of mostly normal bacteria. The odor is often fishy and especially noticeable after sex. Trichomonas, an STD easy to miss with standard testing, also can do it. BV is easily treated with the antibiotic metronidazole. Recheck with your doctor about BV, and maybe also the newer DNA test for trichomonas. Good luck!
