Burning irritation, itchy, mild fishy vaginal odor with very little clear discharge...could it be a yeast infection or bv or what? what otc meds work?

No OTC: There are otc treat. Probiotics such as probalac are effective. Natural ingredients like boric acid has been used to treat BV suppository or douche also vitamin combinations products such as with a, c, d, and others. Also omega-3 fa. Prescription therapy include Clindamycin vaginal gel or Metronidazole vaginal gel or oral tablets.

Probably BV: Bacterial vaginosis is most likely. Yeast infections tend to cause irritation with a thicker, cottage cheese like discharge and a yeasty or bread-like odor. Bv causes a thinner, grey discharge with a typical bad or fishy odor. Monistat 3-day will treat yeast and is over the counter. There is no over the counter treatment for bv. It is typically treated with flagyl.

Bacterial Vaginosis?: Sounds like bacterial vaginosis, aka "gardnerella." it's not an std, but an overgrowth of intestinal bacteria. No otc meds that i know of; responds well to vaginal Metronidazole or clindamycin. You might try gentle douching with white vinegar (1 tbsp to 12 oz water), plus "pro-b probiotic feminine supplements; if not better- see your ob/gyn.
