BV during 1st trimester

Brittany • I'm 25! Have a 9 year old son and a baby girl who was born December 12th 2015 :) BLESSED!
I'll be 8 weeks on Saturday the doctor told me I have BV which is common and to wait til 2nd trimester to get treatment if it didn't clear up on its own...I was reading online that BV can cause problems while pregnant and now I'm worried!  Does anyone have advice or has or are anyone going through this also ??
