3 x good 8 cell embryos
2 x good 7 cell embryos
2 x average 8 cell embryos
1 x average 6 cell embryo
Embryos on day 3 should have developed between 6 and 8 cells, so all have done what they should have. They are then rated "good" "average" or "poor" depending on the quality of cell division (ones that are fragmented or show other signs that I don't understand get lower ratings)
Consequently, transfer will be tomorrow - day 5. We will not know till tomorrow how many embryos we have still developing and what quality and stage they are at (hopefully blastocyst). Approximately 50% embryos will reach blast stage and of course we may get less than that. Please cross your fingers tightly for us that tomorrow goes well; we are all definitely feeling the nerves as well as the excitement.
