Good chance it was fertilized before you got it, so always a chance it will give you baby snowballs. But it looks saddled in the photo, so maybe you do get hybrids. Wouldn't think you could ever get back to a pure line once hybridized. Gestation on cherries and bees is about three weeks, I'd think you could expect eggs to hatch somewhere in that neighborhood.
Nothing good happens fast in an ecosystem.
