BV & pregnancy

I am currently 19 weeks and 3 days pregnant . I got BV when I was 9 weeks and took antibiotics for 1 week. I had it again around 18 weeks and doctor prescribed me antibiotics again but I feel like it hasn't gone away ....ugh I really don't want to take pills again ...has this happened to anyone else? I don't see my doctor until August 26th ....
