Had a MMC last June and being trying unsuccessfully since. Have recently been diagnosed with Graves disease. I'm on meds now. My T3 and T4 are within range after about 6 weeks which is a good start. My TSH is at 0.005 and according to research it should be between 1 and 2 for pregnancy. I've spoken to my endocrinologist about it and he says that it doesn't really make that much of a difference for conception. Has anyone any experience of this? Has anyone heard of anyone similar? Does anyone know of thyroid issues and conceiving. Starting to lose hope. Next line of enquiry, at 39, is ivf.
