Just got the call. She said today they're just checking for cell division.... we have 1x 2 cell and 1x 4 cell. I feel dizzy with relief. But that's just one hurdle down; still three more to go. *bites nails* Still, as far as we know this is the furthest we've ever got, since I never knew whether our last two ever got past being zygotes. So that's something I guess.
