If you've been keeping her quiet she may be overly excitable because she was feeling better.
While a small amount of bleeding from the vulva is sometimes seen after a spay the fact that she cried when jumping off the bed (she really should not be allowed jumping for 10 days) may indicate she pulled an internal stitch and is bleeding from that. I'm guessing there was no blood on the bed so the bleeding started after the leap and cry.
I'd be concerned if she keeps bleeding a lot and here are some general things to check -
If your dog has a rectal temp over 103.5F (normal is 100.5-102.5 Fahrenheit or 38 - 39.2 Celsius ), has gums or tongue that look white, blue, gray or yellow tinted where they are normally pink, has a slow color refill if you press on a pink area of gum or tongue, is having difficulty breathing, or is becoming more lethargic and non responsive to you as time goes on, then you may want to get the dog in to see an emergency vet if one is available in your area.

Otherwise you may want to see/call your treating vet first thing when they open.
Hope this helps you!
