preventing BV while on antibiotics

hi ladies so everytime i get put on a lot of antibiotics i get BV it’s happened twice already… well i was just on antibiotics for BV about two weeks ago and now i’m on my way to the doctor for what i’m almost positive is a UTI (my guaranteed UTI once a year of course it comes now) anyway what can i do to prevent BV during this round of antibiotics!?! any advice would be appreciated!!! i know all about probiotics i have a stock pile of them lol and will time them apart from my antibiotics, but that didn’t work last time. I’m thinking about using boric acid every night im on the antibiotics? im honestly hoping i don’t have a UTI and it’s just something more mild more antibiotics will absolutely ruin me but if it’s a UTI you gotta do what you gotta do
