Eliza please go back to your Endo now. If you can not go to your Endo please get seen by your OBGyn. Your TSH is way too high and may cause problems to support your pregnancy. I have Hashimoto's and I believe that contributed to my last miscarriage. I started spotting/problems at six weeks. I lost the baby at 9 weeks after being told it was a threatened miscarriage. They never gave me an official cause but I will continue to believe my thyroid had something to do with it. After the miscarriage my TSH was around 5 which is way to high for me and probably was around there when I was pregnant. I am currently pregnant and my TSH started climbing around 5 weeks so my current and wonderful Endo increased my synthroid from 150 to 175 and haven't had any spotting or pregnancy complications since and am now around 15 weeks. Good luck and I hope you have a happy and healthy 9 months.
