ROFL BW - an "alien"? I agree that implantation CAN be felt.

As for the blast being fully hatched, I don't know if the standard protocol is to freeze them partially hatched, but it had to wait as it was having PGD performed on it. The nurse was optimistic about the quality - 95% of the cells survived the thaw and it was rehydrating itself (not relying on the rehydrating solution).

I don't know if what I am feeling is the progesterone or wishful thinking ATM.

Thanks for your thoughts x
