Hi Sonya, I've had 2 miscarriages too &amp; (after being ignored for 18 months) have just been put on thyroid meds &amp; progesterone by my new Doc. My tsh has only been slightly high (ranging between 3.2 &amp; 4.7) but he suspected it might be linked. Also my progesterone has always been normal on day 21 but he said levels could drop off too quickly as I get several days of spotting every month before AF. Just wondered what you thought?  Not found many people to ask / talk to about this. xx
