Thanks for any help you can provide.
I can understand that this is really affecting your daughter’s life. Human chorionic gonsdotropin, also known as hCG and estrogen can influence the increase of thyroid hormone in the blood. Now if you daughter is using hormone therapy to replace the thyroid hormone this might interact in the wrong way causing her to miscarriage. Thyroid hormone is very important in normal development of babies brain and it’s nervous system. The first trimmest is the most important here. In what part of the pregnancy does she have the miscarriage? Baby’s thyroid begins to function on its own at 10th week of pregnancy.
I think she should talk to another doctor about medication that she is using.
I hope this helped
