How To Treat Bacterial Vaginosis Inspite Of Taking Pro-B?

My bacterial vaginosis will not go away. I have been on many antibiotics and it just keeps coming back. What do I do to get rid of it? Ive been on represh pro B for 2 weeks and it has done nothing to help me. I need answers because no one will help me. My doctor just tells me it will go away on its own but I have been fighting this since October.
