We worry so much!: You are being careful about guarding against exposures that might harm your developing baby. No matter what we do, some babies will have problems - varying from very minor to life-threatening. My advice is to do the very best you can. Take your prenatal vitamins. Do not use medications unless prescrbed by someone who knows you are pregnant; no recreational drugs! sounds like you're a good mom!
