I would get her checked by the vet. Charlie had stomach pain a couple of weeks ago and he was very out of character, I found him sat in a hedge in the garden soaking from the rain moaning to himself. When I got him inside he just couldn't settle, wouldnt respond to me - just stared into space and started throwing up everywhere. The vet thought hed eaten something that disagreed with him, he had a painkiller, anti sickness injection and was on small meals of bland RC tinned meat for a few days. After the injections he was a bit sleepy but he was comfortable.
The worst thing is not being able to ask them what's wrong, I hope she feels better soon
