None of the other embryos made it to freeze.
Apparently I make a lot of eggs but they all suck. (Seriously -- who starts with 13 eggs and ends up with a 3 day transfer and nothing left to freeze at 5 days? My attrition rates are astronomical.)
So all this means to me right now is that the ones that were transferred back in probably suck too. I'm hopeful that my mood will recover, but this was a bit of a blow.
