I have underactive thyroids but I take medication for it. Been trying since june 2015. I had a very early misscarriage back in November, i would have been 5-6 weeks. Obviously we were both devastated. Been trying ever since with no luck. So went to see doctor yesterday he is sending me for 21 day test to make sure I am ovulating how I should be . Then go from there. Just want some reassurance please
