I was wondering if anyone can help me with this problem. I had my thyroid removed 2 years ago and ever since I have been on euthyrox 125. My tsh 3 months ago was about 1.9, tf3 and tf4 always in the normal range. About 6 weeks ago I started ivf treatment, taking all sorts of hormones (estradiol/hcg/progesterone) and 5 days ago I tested positive for pregnancy. With the hcg blood test, I asked the doctor to check the thyroid levels, just to be sure and I could not believe it: tsh was 17!!!! Tf3 and tf4 are fine.
Apparently the estradiol interfered with the euthyrox! It seems to be a common problem but nobody told me!!! It would have been necessary to monitor tsh right from the start of the ivf treatment. I went to see an endo doctor and she advised me to raise the euthyrox to 188 (one and a half tablet of 125) immediately, which I did.
I was wondering if anyone knows how long it takes for tsh to fall? I feel we are running against time and I am terribly scared that I might loose the baby or that it might get problems due to the high tsh.
I would very much appreciate your help!
