Maybe your answer is here: http://www.motherisk.org/

Motherisk is a research and treatment arm of the Hospital for Sick Children in Toronto. They collect data from around the world, so it is available on one site. And, they supervise high risk pregnancies that involve exposure to pharmaceutical or street drugs. Hopefully, you'll get some insight from them.

It's also a possibility that some of your cognitive symptoms are linked to your hypothyroid condition. Maybe you'll get lucky, now that this condition is being looked after.

Good luck.
