Permanent Yeast Infection?!

I'm so frustrated and upset! I've literally been on antibiotics for yeast atleast twice a month since getting pregnant. I'm sick of it and miserable! My dr just keeps prescribing the same medications but none of them have even changed anything at all. I don't have a lot of sugar in my diet, I don't sleep with underwear on, I haven't been having sex. I'm scared that I'm literally going to have yeast until weeks after I deliver!! I had recently just FINALLY kicked it... for exactly one week until I was diagnosed with BV and the fucking antibiotics for that gave me yeast. I've taken both doses of the medication about a week ago and now I have to wait another 5 days to get more medication even though it's only intensifying.

I feel disgusting and angry. I'm 36 wks and sick to death of this shit.

Has anyone else experienced anything similar? What did your dr do?
