BV and preterm labor

Hi, I’m currently 34 weeks and have had BV several times throughout this pregnancy. I’ve taken metronidazole, clindamycin and have been using metrogel 2 times a week to try to keep it away. To anyone who had BV during pregnancy, when did you have the baby? I’m wondering if I’ll possibly go into labor early because of this chronic BV I’ve had. Thanks!
