Bacterial vaginosis?: The main cause of strong and/or fishy vaginal odor is bacterial vaginosis, caused by overgrowth of mostly normal bacteria. STDs are more common in women with BV, so it's good to know those tests were negative. However, trichomonais (another STD) also causes fishy odor and is easy to miss on routine testing. Return to your doctor; you need an antibiotic prescription, probably metronidazole.
