Just found out have no thyroxine in my body the doctor asked if I had stopped taking it (i havent) and have been researching it and found taking iron and thyroxine stops it working as good. Feel really mad about this as never pointed out to me and low throxine levels can cause development problems and linked to miscarrage. Im having another test today so will let you know if seperating the two has made a difference. Im not saying thats what it is but I wish I knew this imfo so wanted share it with you.x
