Is this a cold? Or some type of flu?

[petep9000]

I'm coughing a little. Not a productive cough, more like a tickly cough. But, I've been nauseous all day and I've noticed alot of mucuous in the back of my throat, probably dripping down my throat into my stomach and making me nasueous. Also, very tired today, and chilly but not enough to read as a 'temp'. But I'm senstitive to these things. Tell me this isn't the flu.
