Lilly has a fever today.........

Lilly did not have the best of nights last night woke up several times and just wasnt comfortable. She has been really quite all morning and not wanting to play. I have been giving her tylenol for pain. I just took her temp 30 min ago and she has a 101 that is 2 hours after the tylenol! I have paged the Dr and waiting for them to call back. She doesn't show any symptoms other than rosey cheeks and not herself.
