Hi everyone, I had an early miscarriage at the end of August and am TTC. I have always had problems with fatigue and my mum has an underactive thyroid. I learned that miscarriage can be caused by this so made an appointment at doctor but kept TTC as I had no evidence I had it. Today the doctor said I had shown slight signs of it in blood tests a few years ago that I was never told about! I am getting tests tomorrow, but am terrified I could have conceived this cycle and that I may miscarriage or have done harm to the embryo before I have a chance to get my thyroid normal. Has anyone had any experience of only starting treatment for this when already pregnant?
