Does anyone know what I can do to improve my endometrial lining? Any advice would be great. Had an early MC 2 months ago and think my lining and my thyroid are the problem. Have sorted thyroid, TSH is now 0.38 from 3.5 so hopefully that will help. (Sorry TMI) Periods are very short, 12-24 hours, and heavy, bright red, no clots, with 1 day of spotting after. I always used to have clots before I had Dd. Had Mireana in for 8 months then taken out 5 months ago. Thanks for reading.
