I'm curious if you had recently taken antibiotics for any other reasons? You can go to the doctor and they will prescribe an antibiotic for you that will take care of the problem short term but you'll probably get it again. My best advice to you, especially if this is your first problem with BV is to try to stay away from antibiotics eat as healthy as possible, get a Lactobacillus supplement and take it orally - you can get them at most health food stores or any place that sells vitamins and supplments, eat lots of yogurt in an attempt to repopulate your system with good bacteria, try RePhresh Vaginal gel - you can buy that over the counter at walgreens - that helps restore the natural acidity in your vagina, and, if that doesn't help the problem you can try inserting a chewable vitamin C tablet overnight and follow that up after a couple days with a chewable Lactobacillus supplement. I use one called L.Reuteri from a name brand called Nature's Sunshine, They dissolve without much mess and they don't leave anything behind like a coating that won't dissolve. We have a health food store in town that carries that brand but I know you can get them on the internet.

Good Luck.
