What to take for bacterial vaginostis

I went for my pelvic exam 2 weeks ago they were suppose to call me for the results but if they didn't that meant everything was fine. A week later I started having burning pain when I pee it didn't happen to when I was going for the pelvic exam. But this time it was more tense. And I was also constipated so I was in so much pain I went to the er and everything came back normal a week later they call me and said I have bacterial vaginostis I dontknow why wait so long to tell me. I call my doctors office and they can't give me an apt until next week because nothing is available I beleive now I had this for 2 weeks and ivebeen in pain almost everyday. I just want to take something over the counter please any advice?
