@Kamiros That's great about E2 level!
Ended up calling clinic who said I was on list but admin couldn't tell me anything. Then missed call from.embryologist driving to get vaccine. Called them back 3 times and no one answered. Finally got through to admin who couldn't tell me anything of course. Then finally got call back from embryologist.
Luckily that was the most stressful part, as all the embryos are doing well. We have 4 x 8 cell embryos, 1 x 10 cell, and 1 that's a speedy little thing and in the word of the embryologist is "showing off" as it's already compacting 
So, as always with the caution things can deteriorate, embryologist is very hopeful we'll have something to freeze
