So we got the final call today (day 6) to say 4 out of 7 embies had made it to blastocyst stage. One was at 3AA grade and the other 3 wer good enough at B or B+ stage. Overall I think this is positive news, and fur awhile, until the wife gets her pylop removed, they will be frozen. We asked to n reference to the "thawing process" and what the chances of survival. Apparently the success rate is quite high at 95% of survival, which was good to know.
It's certainly been a long journey ( not over yet by a long way), but we are hopeful it will work out. At the same time, we're staying firmly on the ground.
