Is her nose warm? If so, she might be sick, but if not, she's probably ok for now. Has she been into anything that you know of? (to drink or eat that wouldn't be healthy?) If not, then she's probably ok. I know there are some members here with animal experience (eskielover???) and you'll probably get better help in a bit.
I did check my dog first aid book, and those simple symptoms are not for anything dangerous... unless you can add more detail which if you had noticed YOU would have taken her already imo (like worms, or bone obstruction.)
Make sure she has a comfy place and fresh water... I hope she feels better soon.
