EJE, don't lose hope. Sometimes bad luck just happens and you just have to hope for the best next time. I went through two PGD cycles and from 31 eggs we got one precious little chromosomally healthy embie. We don't have any underlying chromosome problems, so you can imagine how devastated we were when all our tested embies from our first cycle, and all but one embie from our second cycle had chromosome problems. We had a much higher rate of problems that the average, yet sometimes it happens

I wish you all the best and hope you have some good luck soon!
