I have had problems with hypothyroidism for years. I get my levels checked every 6 weeks atm.

My levels have been really odd during pg, my endocrinologist said that my levels will not affect the baby as babies start producing their own thyroid at the end of the first trimester.

I'm sorry I can't offer any better advice, all I can say is the endocrinologist I see is highly recommended and I trust what he recommends.
