Yeast infection...

I'm 33 weeks pregnant, and all my pregnancy I've gotten yeast infections, they'll go away for 2 weeks and come back , I've gone to the doctor and they've given me creams, I believe it's from having sex with me husband ..that I get treated and he doesn't so it just goes back and fourth.. well anyways this time I can't stand the itch and the burning... but I'm too embarrassed to go to the doctors ..I wanted to know what's save to buy for a yeast infection while pregnant.. please no bad comments I just want to get rid of it fast

(I've gotten tested for stds and I'm clean)
