Calling my nurse tmrw

I’m just wondering what else they could do for me about my BV? They prescribed me nidagel, it worked but my BV came back. Now I was just on metronidazole & I still have my symptoms (yellow discharge & some burning)... I haven’t had sex in 2 weeks & it’s really annoying lol.

Nothing is working & I’m also pregnant so I’m not sure what else they can do for me. Has anyone dealt with this? (BV was confirmed with a swab about a week or 2 ago) also got swabbed for other STI’s & all were negative.
