Aww...so many people read this but no one replied to you. Sorry.
Well, I have never been pregnant in my life yet (but I plan to be by the end of this year...see how it goes!) and I'm not familiar with those types of drugs, but I would suggest, if you haven't gone already, to go and see your doctor (do you have one)? They will know about drug interactions better than anyone else on this board. If you don't have a doctor, maybe a clinic? I know wait times are bad but if you're worried enough then it's worth it. I know that I would be worried too, the first trimester is the most important one for development of the baby's brain. Once you get some answers your pregnancy will only get better, as you will be more knowledgeable on what to do/what to avoid, and you'll have less stress running through you, which is better for the baby. So the only advice I can give you is start taking folic acid (pre-natal) vitamins asap. Good luck, I wish you all the best!
