I keep having recurrent bv for a lil over a year now and also a lil over a year that i startrd bleeding during sex though i have no stds, and if i bleed during sex i most definitely do end up with some bv shortly after but the doctor's seem to have no explanation for me,do i have to live like this the rest of my life? Did anyonr go through this? Now I am pregnant its vrry scary because seeing blood u think the worst :(
