HI, I'm joining this a little late, but i've been doing some reading about increase TSH levels. I have been trying to get pregnant for 6 months with not luck and just had some labs drawn. my TSH is 4.19, which is the high side of normal. During my research i've found a high TSH is a reason for miscarriages. I'm sure if you've been to OBs they've checked, but I just thought I'd throw it out there.
I know 6 months of trying is not too long. The ups and downs of emotions are there. My heart goes out to you who have had losses and much longer of trying times.
Best of luck.
I was also diagnosed with the same thing and I had 3 miscarriages prior to getting pregnant and delivering my little girl. What worked is that my doctor put me on Heparin, 4 mg Folic Acid and Folgard which is a combo of Vitamin B and Folic Acid. Hope everything works out great for you!
im so sorry for your loss. I hope with your new treatment plan you will soon have a happy healthy nine months:) Take care and i will keep u in my prayers
