Don't be scared hun! I had to take that med a whole bunch of times. I got BV a lot when I was prego. Just eat something and you will be just fine. The worst thing that can happen is if you have alcohol (and you shouldn't be drinking anyways I had not one single issue with it. You can relax, you will be just fine. I was also strep B positive during labor and had to have 2 doses of antiobiotcs and I was terrified because I couldn't eat and they were strong IV antibiotics. I asked them for an anti emet which that gave me with no problems and I never felt sick. hang in there ok, eat and take the meds, you will be ok hUGS!!
