I am 34 weeks pregnant and am very concerned about all these antibiotics (about 4) i took during my pregnancy, 3 were zithromycin z pack and one was metronidazole for bacterial vaginosis in my third trimester. For all these antibiotics, i received strong reassurance that they are safe to take to treat my common occuring respiratory infections. I am concerned. Is there anyone here who took many antbx during pregnancy and had a healthy child? AMEN... thank you
