I can finally breathe...we got our report from the embryologist! Of the 8 that fertilized, all are still growing. Current standing:
2 at four cells--these are a little slow, but she said they will continue to be cultured and have a good chance of catching up to the others.
1 at five cells--the embryologist felt like this one would almost definitely catch up.
3 at six cells
1 at seven cells
1 at 8 cells
Now they just rest until transfer day on Sunday...well, not really rest. They have lots of dividing to do!
