Bacterial Vaginosis

So I have been having this reoccurring issue with getting Bacterial vaginosis ever since me and my fiance started dating and it only occurred after we had sex a few times. My doctor is telling me theres nothing I can do about it, but i get them so frequently and i just dont wanna believe that i just have to keep taking antibiotics every month. Has anyone else had this issue before and gotten actual help with it or am I just screwed?
