I would discuss this with my pdoc, if I were you, even possibly put pregnancy on hold till you are made assured that it is safe, or see if any safe alternatives can replace what you are taking, personally I cannpt see giving up possible normalcy vs mania, for getting pregnant, it is best to be stable, totally, before deciding to bring a new life into this world, I think it would be totally cruel to mess with the health of a fetus, and unfair to this child.
Sorry, just my 2 cents

But take this up with the prescribing physician.
Good luck,
