I'm so confused and worried about my thyroid. It was 4 after my 1st m/c and I was put on 100mg synthroid. I got pr right away and afterwards had TSH of .25. But then about a month later, my RE lowered my meds to 25 mg synthroid about 3 weeks ago and I m/c around that same time again. Now, 2 weeks after the m/c and about 3-4 weeks on the lower dose, my TSH is only 0.015. I feel like I have a fever all the time (but i don't) and am now wondering if the hyper thyroidism could have played any role in my 2nd m/c. I'm also really confused about why it got so out of whack when I went to a much lower dose. Can anyone help shed some light on this? Thanks so much.
