I've recently been reading into the side effects on the baby if you conceive while taking clomid and it has me a little concerned. Things like spina bifda, club foot, down syndrome, autism, ect have all been linked to this drug. Since clomid stays in your system for approximately 4-6 weeks, possibly up to 11 weeks, the fetus can be exposed to this class x drug. Some sites claim the results may be skewed because women using clomid generally have other risk factors (such as being over 35) and it's hard to say whether the defects were caused by the clomid or other factors such as the ones that caused the infertility itself. I just conceived my second with the use of clomid due to unexplained secondary infertility and now I'm panicking because I was not made aware of these risks. I'm wondering how prevalent these side effects are. If you have conceived before using clomid, please participate in this poll and comment what birth defects it may have caused. If you haven't conceived or do not yet know if your baby has any defects or autism, please hit the 'poll' option.
