fever??

Jodi
I have a temperature fluctuating between 99.5 and 100.3. I took 650mg of Tylenol and an hour later my temperature is still fluctuating. I'm afraid to go to bed and have my temperature go up while I'm sleeping. Any ideas? The bottle said to take two 650mg tablets but that's for non pregnant people, would it apply to me too? Should I take one more?  
(Cool baths etc just make me shiver and then my temp goes up higher than before)
