BV during TWW what should I do!?

Antibiotics don’t work for me :( they have for a short time but it just comes back whenever I have sex and also gives me either a uti or a yeast infection. Boric acid works, but I’ve heard it can hurt a developing embryo. But BV can cause miscarriage. I just started a good probiotic today, but I’m not sure what else to do in the mean time. Should I keep using boric acid until I get Bfp? I would really appreciate some advice, can’t get into the doctor for another week.
