Bv ...again?!

So back when I was around 9 weeks I was out on flagyl for bv and again around 14 weeks.... with an internal antibiotic...

I'm having some of the same symptoms again of bv (discharge, slight smell, uncomfortable feeling down there/need to use the bathroom constantly). We are traveling 1000 miles for my sisters wedding next weekend and will be gone all this week. I'm currently 18 weeks and a few days and just wondering everyone's opinions on letting it go til next week when I can see my dr.

Can constant bv while pregnant hurt my baby???
