:)I remember being pregnant and worrying about harming my babies all the time. Thank God all of them are healthy!! Anyway, it's normal for expecting parents, especially the mom carrying the baby, to worry. Try to remain rational whenever you start feeling this way and eventually you will feel better. Even if you did come in contact with a carcinogen, (which you didn't), your baby's organs are developed and now he is just growing. Try too remember that and eventually you will feel better. Have a healthy and stress-free rest of your pregnancy!
