It's a hard one isn't it. We're about to have our second through IVF and have (I think!) 3 blasties on ice. While we have said that we might try naturally for a third but not go back to IVF, we will still keep storing for a while yet.
I guess we are basing that on keeping our options as open as possible. As much as I don't want to I wouldn't completely rule out giving our blasties another shot, and I don't think I could donate them while our family is incomplete (even if we are trying naturally), does that make sense?
The fact that you are even asking the question says to me you aren't ready to let your little frosty go yet, so I would keep it on ice for awhile...
