My TSH levels are 3.05. Doctor said I need to use levithytoxine cause it  needs to be less than 2 during pregnancy. But I've never used thyroid medicine (levels have always been below 2 even for my first pregnancy) needless to say I'm even more nervous about using medicine during pregnancy. Can somebody lead me in the right direction please ! I don't want to risk my baby's IQ which the doctor said is developing now and Needs the thyroid but has anyone gone through this ????  Please advise !
