So sorry for your loss Kooki. Xxx
My 3rd fet, I miscarried 1st January. Bled for 13 days. Completely resolved and no intervention necessary. They just checked my hcg every week and it fell away to zero by about day 20. I didn't get my period for 45 days though (counting from 1st jan). I was also 5wks and about 3 days.
After 3 failed fet my fs preferred to run further tests - autoimmune tests and an endometrial biopsy which was last week and had to be after day 14 of my cycle. Now waiting for next af and I will transfer one of my last 2 frosties.
