I was born without my thyroid,
and have been on
Synthroid all my life. My pediatrician told my mother that I would not have any children. I had my first child at 21, my second at 26, both carried to term. I am now 31 and have had two consecutive miscarriages in four months. When I began menstruating I was very regular, every 28 days, and many cycles down to the hour. After my first child my cycles were shorter-24 days. Ovulating at about day 10 every cycle.
