Chronic pH issues

BV on and off. I'm pregnant and it's getting bad.

Anyone found a way to resolve chronic pH issues?

I'd go on the antibiotic just to relapse into BV a few weeks later, usually after developing a yeast infection . I've tried vaginally inserting probiotics (kind of helps but the grit from it irritates my skin), sits baths, washing with water only.... about to try boric acid again
