Thyroid and miscarriage

Tay
Currently experiencing my second miscarriage. I am 24 years old, healthy active, happy etc. I have had dark hairs growing on my chin since I was about 18, I used to ask doctors all the time why I seemed to be growing facial hair, and all of them just put me on a different contraceptive pill. I've been looking into tests that are done after multiple miscarriages and am thinking of specifically asking to have my thyroid checked as I know that an under active thyroid is linked to hormone imbalances which greatly affect a women's chance of miscarriage in early pregnancy. Does anyone have any experience with this? Thanks ladies xx
