I just did my 5 day transfer , they placed 2 Grade A blasts, and I had 1 6 day Grade A blast to freeze. Just want this to work so badly. I had some slight cramping day of transfer, and cramping continued for 2nd day and got a bit stronger. Today on day 3 it is very mild and sporatic cramping. Did you get 2 blasts, they split for a triplet preg. Very happy for your success and your beautiful children. Did you do amniocentisis?
