All 12 fertilized eggs have become embryos. 11 of the 12 have become 4 cell embryos and 1 is 2 cell. Of the 11 that have 4 cells, 7 of them are grade 1 (highest), 4 are grade 2 (still good). Looks like we should be having a day 5 transfer on Monday. Things are looking good!! Feeling quite blessed and happy with how things are going!
