max,

you know blastocyst culture is still a fairly new development in the world of ART. Before it came along, women only ever had day 2 or 3 transfers, and there are many, many, many IVF children out there to show for it.

I know it's been a disappointing cycle for you, but getting to transfer means hope. I know of many women who have had beautiful chidlren from grade 3 fragmented embryos. So odette's right, don't give up hope.
