I really need some advice,guidance and most importantly prayer. My fiancé and I have been trying to have a baby for five months. Yesterday I went to see my Obgyn for the first time to get checked out and make sure everything is ok. As she is checking me she noticed that my thyroid was a little big. I explained to her that I went through this a few years ago. I had a blood test,a sonogram and a biopsy done. The test came back the right side was ok,but the left side was a little abnormal,but not not too major. I was told to come back in a year. Last March 22,2015 I had a miscarriage at 17 weeks (fetus was measured at 14 wks). Since then I have been trying to figure out what it could have been. Not all my pregnancies have been to full term, but this was my first miscarriage . I've had three full term and two premature births. Since leaving the doctors office I have been reading up on my thyroid and how it could affect a womans chance of conceiving. I am really starting to wonder if my abnormal thyroid was the reason of our baby passing. I am so confused and really hurt (all over again). Has or is anyone dealing with this? Please comment.
