bacterial vaginitis
"My doctor gave me 500 mg of Metronidazole which was about  four pills to take as a single dose. I went to the doctor after finding out my guy has been having unprotected sex with another woman as well as myself. I think maybe it threw off my Ph balance. I also had a UTI but so far it seems like it worked.  I won't know for sure for two weeks when I go back for my other STD test results. I hope it is gone but I didn't experience any side effects."
