J.P.
I've always been told to judge the severity of the illness by how the child is acting. If she doesn't seem to feel bad, don't worry too much. I never like to take mine to the doctor unless I have to, in fear of exposing them to even worse germs! I'd go with extra fluids and rest, and keep an eye on her. Maybe a little extra vitamin C (I give my 20 month old half water half OJ). Good luck!
