Odds are she is ok, but I would probably skip dinner and let that stuff work it's way out of her system. Keep an eye for problem signs, like trying to vomit with no results, tender to the touch belly, inability to lie down comfortably, more than a few drops of blood in her poop. A very small amount of blood can just be the result of an irritated digestive tract, but more than that (or any of the other symptoms) and I'd head to the vet. For the diarrhea you can give her some 100% pure pumpkin (you can get this in a can by the pie fillings, just don't buy pumpkin pie filling!). The fiber helps to bind things - a tablespoon at a time a couple of times per day.
Hope she feels better soon!
Also, be sure she is drinking plenty of water to prevent dehydration - which is easy to get with diarrhea.
