11 eggs retrieved
9 fertilized
7 kept growing, 2 look good
Today: Have to do a day 3 transfer today with the 2 good ones because doc isn't confident we'll have any left at day 5. 
Totally crushed, but I want to stay calm and optimistic for the transfer this afternoon. 
Any thoughts or experiences you can share would really help!
