First of all, congratulations on getting 3 eggs and having 2 fertilize. I know you're focused on the fragmentation issues (and I suspect I would feel the same way) but I really do believe that number of cells at transfer has a lot more to do with success than does fragmentation. Ideally, of course we all want totally perfect embies, but it rarely works out like that and there are plenty of success stories from less than perfect looking embryos. It looks like you may have a 10-cell and a 6-cell tomorrow (assuming they continue to double in cell number). Those BOTH have a good, fighting chance. So, while I know you're tired and disheartened (and I don't blame you at all) I think there is cause for hope. In case you're interested, here's a thread I found on another site about people transferring fragmented embryos (check out the signatures of the posters and notice how many of them were successful- a lot!):
Thinking of you and hoping for the best!
