I think I may be coming down with pneumonia. How soon should I get to a doctor?

I have just started a new job and don't want to get an occurence.. I only work 8-1 tomorrow. I felt kind of bad yesterday and worse today (I even took a nap which I NEVER do unless I'm sick.) My main concern is i feel like I have a growing ammount of fluid in my lungs esp. when I inhale and also right as I'm first exhaling. My sore throat is awful (fixing to gargle w salt water). I have fever, mild chills, cough, mild stomach discomfort (ofcoarse that could be the Red Lobster I ate yest) the fluid filling thing and chest pain. Watery eyes, and sweats.. I guess what I'm asking is could this be pneumonia and if so how long can I wait to go to doc? Tomorrow is xmas eve and I'm sure my doc isn't open and I really don't want to go to the ER or urgent care clinic. Would I be able to wait to go to doc if it's pneumonia?
