Prescription

I was just predcribed Flagyl and Im 10 weeks and 1 day and I just keep reading the horror stories about its not safe during 1st Trimester I tried to wait but the symptoms of BV are too overwhelming for me. I took one today should I stop and wait or just continue I had one doctor tell me wait but than my primary midwife says she treats it in the first trimester so I am confused 😱
