she probably woke up and was wondering where you were. because she used to sleep in the bedroom where you sleep. can't she sleep in the bedroom again? i wouldn't recommend letting her on your bed though, because after i let milu sleep on the bed, there is no going back, now she won't sleep in her crate anymore.
if she can't sleep in the bedroom for some reason, at least give her something with your scent on it. but i hope she can sleep in the bedroom as well.
