I am a 36 y/o female with no history of fertility issues (am overweight). I have had two healthy children and trying for third. I have suffered two consecutive miscarriages and the only difference between then and now (4 years since birth of second child) is I am taking 112 mcg Synthroid. My most recent blood tests shows: TSH - .147, T4 - 11.9, and T3 - 124. Could the TSH be the cause of my pregnancy losses? Thank you.
