AmandaM,
I'm so sorry to hear your news.

I have heard that 3 times is a charm and that the average is about 3 to 4 cycles to have a successful ivf. Keep your chin up. So best of luck on your third try. I'll be thinking of you!
The fragmentation issue tends to be a problem. During my first cycle, I looked at the pics that the RE office gave me of my embryos and thought the same thing (that they were fragmented). During this cycle, I held the photos up together of this cycle and the last cycle. I could REALLY tell the difference. The embryos in my first cycle were not as healthy looking as the embryos from this cycle. Plus, none of the embryos from the first cycle were at the 8 cell stage. (Second cycle..all were at 8 cell stage). Being older, I kind of expected fragmentation to occur.
Good news, I had my first U/S today. My DH and I were able to view 2 sacs AND both heartbeats! This was a plus since i'm a pessimist by nature and tend to be really guarded (in fear of dissappointment). Then the Dr. told me of Vanishing Twins (which I already knew a little about). I have to keep my fingers crossed and hope that the twins survive.
AmandaM, did you ever consider donor eggs? Perhaps have donor eggs with your husband's sperm and possibly have them implanted in you? Just a thought..
