if she's crying thats a good thing.
both my boys have done it.
DJ- off the bed at 7months. off the couch - too many times to count (mainly since being able to get up there himself) also down two steps at a friends place.

Vic- off the couch onto floor boards. off the bed - landing on his bum once and head once.

as long as she is awake and happy she'll be ok. if she starts throwing up/acting sleepy (when she's not normaly due to for a sleep) then pop down to the doctors. they get a massive shock when they ground comes up to play with them
hope you're ok though
