I called the RE's office to get the whole poop on the embryos' cell counts. The three that were transferred were all 8-cell (yea!), and two of those were compacted (huh? Accompanied by Scooby Doo like shaking of the head). The nurse (and Dr. Google) says that means they were about to divide again. At which point they would be morulas. The others were an 8-cell, a 6-cell and a 5-cell. I don't know what they've done since or how many got frozen.
So definitely the best embryos we have ever produced. Maybe the wheatgrass (ack!), zinc, fish oil (ack! ack!), acupuncture and working out helped. Or maybe I am being led down the primrose path yet again.
It is Day 4 s/p 3 day transfer...
