I have low thyroid so my doctor put me on armour thyroid which is thyroid from pigs. My husband and I are thinking about baby #2 (we have a little boy<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/love.gif" style="border:0px solid;" title="love"> ) but I'm afraid to get pregnant without knowing if it is completely safe while taking this pig thyroid. My doctor said it is safe but I have heard of other stories where a woman was taking meds that her doctor said were safe to take while pregnant and then she found out it was actually very risky! If anyone knows anything about this please comment. THANKS!
