Maybe I misread the original post - I thought was talking about the levels of the Hashimotos antibodies in particular? and my experience was these have never been rechecked is only the T3, T4 and TSH levels that are checked. So in essence I have been treated the same as others who have low thyroid but don't have Hashimotos. Isn't it the low or high thyroid levels that are the issue in pregnancy rather than the antibodies?
