I was wondering if you have been taking prenatal vitamins for the entire time that you have been TTC. I have been taking them for the past year and a half, because I thought that was what I was supposed to do. In the past, my doctor prescribed me PreNexa (prenatal vitamin), but I am not seeing that doctor anymore. I have been having trouble with constipation and bleeding when I go to the bathroom, and I read that folic acid and iron in prenatal vitamins can cause this. So I called my new doctor and asked to be put on PreNexa b/c that has a stool softener. Well, the new doctor says he couldn't prescribe a Prenatal Vitamin until I was pregnant. I explained to him that I was concerned b/c birth defects run in our family (my brother & aunt have cleft lip/palate), and I wanted to make sure I was getting the correct vitamins. The nurse still said that it would be ok if I was just taking a multivitamin, does this seem right to you? I thought I heard that you are supposed to take prenatal vitamins before you conceive...Let me know your thoughts. Thanks!
