So I saw my endocrinologist today (who I am not particularly fond of), and even though my TSH and other thyroid levels are all fine, he wants me to take 50 mcg of levothyroxine through my whole pregnancy because of the autoimmune antibodies (which I guess can cause premature delivery and miscarriage?). I most likely had this while pregnant with DS, and everything was fine...but I don't know what to do. I am on the fence. He basically said it is a preventative thing, and there was only one study done on women with normal thyroid but + antibodies taking it. I know thyroid meds are pretty safe in pregnancy, but I don't want to take them unnecessarily. Ahhh. Thoughts?
