BV that won't go away?

I've been dealing with BV for MONTHS! (Since January) My doctor keeps giving my antibiotics but they aren't working. I have a second opinion on Wednesday but honestly I'm so defeated. I can't have sex because it hurts. My husband is a trooper, but it's really starting to affect our relationship and also my self esteem. I'm starting to feel like I'm going to be stuck like this forever. Has anyone else gone through this?
