Hey topcat. I too had day two transfer and they were both at 4 cells. They like to do a day two transfer because days three is normally the make or break stage i think and its normally very hard for them to make it past then. I had my transfer saturday before you. I think implant is between days 4 to 6 my clinic told me. Good luck with it all. There is another thread just under this one that says Blast Vs day 2 transfer. Have a read of it its very interesting
