Were you on it the entire time?
Hey. I'm also on PTU for hyperthyroidism. This will be my 2nd pregnancy on this drug. My last baby was born a week late and a very healthy 10lb 10oz. I'm am under a great Endocrinologist this time so feel even more confident that things will go to plan once again. PTU is the safest drug for hyperthyroidism for a pregnant woman to be on.
