I am 1 month pregnant and I have bv. Is there anything safe I can try to limit the symptoms (discharge and smell) until I am along far enough to use antibiotics. Thanks.

I would talk to your doctor about this. He might be able to give your proper antibiotics, but he might prescribe a topical antibiotic or antifungal as the case may warrant. Worst case, he can just suggest what you can do until he can prescribe something.
