Weird and Sporadic Fevers

For the past 2 weeks Liv spikes fevers of 102 at completely random times.  No symptoms of being sick.  She did great all weekend long.  It was the first time in a month that she was finally back to her old self and then bam - she gets a fever this morning.  I'm taking her to the doctors today.  Hopefully they can figure out why there's no rhyme or reason to these fevers.
