Can't get rid of BV infection

Hey guys.. I'm starting to get really nervous because I have been treated for BV with oral antibiotics which didn't work and then the topical antibiotic (Metro Gel) and finished it last week and I just felt wetness and looked and had some of the greenish discharge again 😩 I'm 34 weeks and am getting nervous because I know it is dangerous for the baby once I start dilating and I'm so frustrated with my doctor that she can't control my infection! Has anyone else experienced this? I did put in another call to my doctor.. Just looking for support. Thank you
