BV treatment?

Kristina • Married to the love of my life with two beautiful sons!
Hello ladies! My doctor called and I had a mild case of bacterial vaginosis after my pelvic exam (not sure where it came from as I don't know much about it and have only been with my husband but oh well). She prescribed me a vaginal suppository for 7days for treatment. However everywhere I have read says if you are pregnant you will have to take pills, not the suppository. I am a little concerned as I don't want to hurt our son. Anyone have experience with this? Thanks in advance!
