Have any of you had bacterial vaginosis during pregnancy & did everything turn out to be ok?

I’m 5 weeks pregnant and I’m positive I have bacterial vaginosis back for the 5th time. I read online if not treated it can cause miscarriages or even preterm labor…I guess most doctors dont treat this until the second trimester..Im really worried about waiting & I dont want to take the antibiotics & that cause birth defects. Has anyone else out there gone through this?
