Down to 7!

I don't think my heart can handle any more loss. I am celebrating that we have 7 because it is obviously the most we have had but I am still curious as to why we started out with 16 eggs and only have 7 embryos. Last time I only retrieved 2 eggs and we got 2 embryos so I guess that adds to the shock value.
I am doing my best to keep my eye on the prize and to remember that all we need is one good egg and that if we have 7 by day 5 then that still gives us a couple of frosties. We still haven't heard if we will be doing a day 3 or day 5 transfer. Fingers crossed that we can go to 5 days! By the way I am still working on hubby to transfer 3 embryos instead of 2 because I just want this to work so badly!
