Anjana- I am in a very similar situation. Can you please let me know if everything went well and that the baby is healthy? Your response would be of tremendous help. I am freaking out here.

My understanding is that medications will have no effect on a pregnancy until the placenta forms which is closer to 9-10 weeks.  I wouldn't think that taking medication so early into your pregnancy would cause a problem but you will need to double check with your obgyn.  Also, don't forget that because a medication "can" cause birth defects that doesn't mean it "will". Even with class D medications the likelihood of defects is very low.
