You might be interested in the website safefetus.com. They have info on the safety classification for many meds during pregnancy (A-D, X) and they explain the system if you are not familiar with it. I looked and Triliptal is a "C" (not a D like Lithium) so your docs might be okay with it. Definitely do have a good discussion though. I also ended up seeking (more than one) 2nd opinion, so that might be helpful too.

Best,
