In case you are confused by the titles the past two days...here's how to decipher it: 4 days past 3 day transfer (or 4dp3dt).
I talked to the IVF lab this morning. We have nothing to freeze. The two they were watching made it to the blastocyst stage (step one of being able to freeze), but they did not have an inner cell mass. Had no clue what that meant so here is a picture I found on wikipedia:
It appears that the inner cell mass is what actually allows the baby to grow and develop so they do not freeze if it isn't there. She was quick to remind me that all fertilized eggs are different so not to be concerned about the ones that were transferred. And, to be honest, I hadn't even thought about that until she said it. Thanks!
I also checked the grading for the two we had transferred because I didn't recall finding out on Thursday - the 8 cell was graded 3+. I believe they grade on a 1-4 scale with 4 being the best, is this right, Jamie? (another question I should have asked before getting off the phone). Apparently, they do not grade the morula's, but she said that it was very nice.
