BV and Complications

I get BV all the time on a regular basis. I have only had it once during my pregnancy at the end of my second trimester. I am currently 35 weeks and was having clear drainage that overflowed my pantiliner. I was concerned my water was leaking so I went to Triage and was diagnosed with BV. Well they told me they don't treat it late in the third trimester and when I tried to figure out why all I can find is information about it causing preterm labor, and PPROM. Well now I'm freaked out. Anyone have experience with this? I don't want a NICU baby! TIA.
