Good: We want to be very sure that the thyroid hormone levels do not drop low while she's pregnant. I would not be concerned otherwise.

No effect on baby: Radioactive iodine will have decayed, no residual radioactivity to affect baby or his development. Low TSH is good oncologically, but not sure how tfts affect pregnant women, would make sure she is seeing an endocrinologist and probably a high risk ob.
