I think she is fine. Whenever I have a question like this I go to my pediatrician's website and hit FAQs. They have a spot where you can click on a drop down menu for the symptom, e.g., FEVER, then it will give you the whole low-down on what to expect and when to call the pediatrician. It's great.
Go to crownpointpediatrics.com and check out FEVER, it will outline in detail for you.
Good luck!
