How dangerous is Bacterial Vaginosis in the First Trimester?

I had bv during the first trimester with my past two pregnancies. My ob would not treat me until 12 weeks because the risks of the medication far outweigh the risks of the infection. It is certainly an inconvenience to deal with bv but it is better than harming the baby with medication. Just wait it out until safe to be treated. My kids are healthy and I waited for treatment.
