possible failed ICSI Fertilization

While the first day after your Egg Retrieval is usually the happiest filled with hope and wonder how many of your egg fertilize.
I was simply one of the unlucky ones that didn't have my eggs make it to fertilization.
While I was waiting all morning for my Dr to call with the results, I knew the longer and longer the wait, the worst of the news. While I was getting our 2 year old out of the pool and ready for nap, my Dr. called and I didn't even hear to the phone.
In the nicest way possible he left a message letting me know that yes they were able to get 6 eggs, and after waiting the 6-8 hours to see how many are mature. By then, only 4 had made it and they  performed the ICSI (they take one sign sperm and inject it into an egg, making it impossible to not just fertilize, unless your me I guess) So with 4 being injected they have to sit and wait until the next morning to see the signs that it had fertilized. I guess they were just waiting it out trying to see if anyone of them would and not a sign that one had fertilized. On his message he did say he would check back in Sunday because maybe it could still happen, that we still had hope, but I think he was just saying that maybe there is a 1% chance of that happening.
I guess I can only hold my breath until Sunday now.

My husband called back and the nurse said she would check the lab tomorrow and give us a call Saturday to see if there is any hope.
