Hi Caramel!
I'm so sorry to hear that, I know for me and a lot of other ladies that is a common side effect of those treatments. those harsh treatments combined with just all the stress of the whole ordeal can do it to you. But I have read some really encouraging things about people using AVC cream to prevent bv, be careful though because it is an antibiotic i think, is it the 30 day prescription? the stuff if supposed to work really well so im sure bv is not going to come back
do you have a kit to measure your pH at home? it might be a good way to track how you're doing... Relax and let yourself heal, and be sure to post how the AVC works!
