Of the 10 retrieved 8 were mature & 4 fertilized. I call back tomorrow to see how the 4 are doing. If any are "meh" then I go in Sunday for a day 3 transfer. They'll still watch any that are left for freezing but practice policy is you need @ least 4 good embies to do a day 5. If they're all waving "yay flags" then we do a day 5 transfer on Tuesday. In a perfect world we'd transfer 2 & have 2 to freeze but like everything else, assume nothing, right?
