Oh honey... All of that can be from your undiagnosed hypothyroidism... Even the miscarriage. Any doctor worth his degree would know that TSH above 5 merits treatment... And a really
good doctor would suspect hypoT with those symptoms and TSH above 2!
Your pregnancies likely activated the thyroid antibodies which most often cause hypoT. That's a very common occurrence.
gather your strength to demand a prescription for thyroid hormone ASAP. If your MD refuses... Please go to someone else! You have small children, and they deserve as healthy a mother as they can get. Don't let some stupid MD ruin that for all of you.
I would love to know what happens, if you'd be so kind as to post back after you make your demand. Good luck.
