Bv!? Help !!? Firs pregnancy

Melissa

Hi! I’m currently 16 weeks pregnant & I feel as I have bacterial vaginosis again. I spoke to my midwife about it and they did a vaginal culture but have not gave me the results back of it being Bv or yeast infection although she prescribed me “ metronidazole “I’m worried because it is a antibiotic. Has anyone ever had bacterial vaginosis while pregnant??? HELP! First pregnancy and worried.
