Bacterial Vagenosis

So ever since I lost my virginity 4 1/2 years ago to my Fiancé. I started having discharge and over these couple of years I went to my OB as much as I could afford without insurance and she has not been able to give me any type of antibiotic or medicine to fix my problems. I've gained and lost many symptoms over the years and within the past couple of months decided to get off birth control to see if it would help any. Nothing changed :( 
Don't know if anyone has experienced this but my OB said it was most likely Bacterial Vagenosis which is kinda like a hardcore yeast infection. Any references to antibiotics my fiancé and I can take to make this go away would be greatly appreciated since I'm getting tired of trying and failing.
