I don't want to tell you not to get treated, especially if you are having symptoms, but I went to all the sites, and they talk about worse case scenario as though it is the most common occurence.
How far along are you?
My original doctor agreed that it was probably not worth treating. I changed doctors (I moved) and the new doctor wanted to treat me just three weeks ago. I declined, as I read that even after treatment the BV can come back in just a few weeks. I certainly did not want to have to undergo a second treatment.
(Especially, as there seems to be a lot evidence regarding the effects of the antibiotics on the baby.)
But then the doctor said not the way I treat it, meaning she prescribes high dosages.
I was well into my third tri, so I had to be firm.
But I think the major difference might be that this has always been part of my vaginal flora, with no symptoms.
Good Luck
It's a hard decision.
