I have just found out I am pregnant (5 weeks) and I have Graves Disease. I used to by hypothyroid (for about 12months) then I was hyperthyroid (for about 6 months) now have Graves Disease. My question is What are the risks to the baby? To myself? I have read about Downs being related, but need this clarifying. We have a Downs Niece. I am on PTU in small dose. I am also 38.
