You can't freeze eggs BW, only embryos I'm afraid. And my clinic has a 10 year holding period, increased from 5 years about 2 years ago. I don't know if it's the same for every clinic though?

Funny this thread got me talking to my DH about our last remaining embryo and, because of how strongly I feel about it, he is now conceded to going back for it eventually, but he won't promise when. I told him I'm almost 37 now and I want it to be before I'm 40, and I am hoping that's what's been agreed upon and he doesn't change his mind again between now and then!
