I cant get pregnant

My husband and I just started trying to get pregnant, to my surprise I got my period, I have been taking vitamins, eating well, we tried 3 days before, on the day of ovulation and 3 days after ovulation and nothing. I was diagnosed about a year ago with bacterial vaginosis, I have been treated on it several times and it keeps coming back, I didnt have it when we tried to get pregnant, is it posible that bacterial vaginosis is keeping me from gettin pregnant?, I really need the help, I am geting really drepressed.
