Sore Throat, Headache, Tired, No fever ?!?

I woke up this morning with a sore throat. Now, around 6:20 p.m I have a headache and I've become tired and body aches, but no fever? Sounds kinda like swine to me? What do you think? I don't want to go to school tomorrow if I feel like this, but my mom already told me I HAVE to go. Help ?
