Answer
HI;
    Brittany,    
         Well if I were you first I would get the radeator pressure tested and it will let you know if you have a leak as that could cause your condition , also you could have a bad rad. cap - or a bad thermastadt.So if this can be done it should fix your problum and don't forget antifreeze.
GOOD LUCK
