I just got a call from Mia, who had just received a joint call from both Dr. Sleepy and the embryologist.
All 13 embryos are growing strong. Each has 4 cells and none have the dark coloring, asymmetry, or small size that the last batch did. Dr. Sleepy said that he did not expect that Mia would do so well and the embryologist was flabbergasted at the sharp improvement between this cycle and the last. Needless to say, we're likely going to have a 5-day blast transfer on Monday. They'll still call me in the morning to let me know for sure.
