BV right before conception?

Anybody get BV right before they conceived or right when they found out they were pregnant? I've had it before years ago and now it's back. I stopped my BC a month ago because we are TTC. I'm waiting for my period as we speak (hopefully it doesn't show up!) and I noticed that BV odor a few days ago. Just wondering why it came back at this time when we are TTC. I have an OBGYN appointment coming up soon.
