Pneumonia, flu, allergies, or cold?

Alright guys, I got the H1N1 vaccine before so I doubt I have that. I also had pneumonia like 5 months ago or something like that, but I took antibiotics for 10 days as the doctor instructed me to. I think I have minor allergies, but it's really hard to say for me. Anyways, the only reason I am posting this is because I'm worried im getting pneumonia again since I noticed that at the beginning of the day I had the faintest chest congestion, and now it's building up and it sometimes hurts when I breathe or bend the wrong way. Sometimes it happens pretty much randomly. I also have a runny nose, I used to have a faint sore throat, my ears are plugged and I'm coughing. It feels like some of my coughs are post nasal drip while others are coming from my lungs like in pneumonia. I haven't really felt nauseous but I felt pretty bad the day I came back from summer camp as I went to bed early. My other friends at camp were getting a little sick but they just seemed like colds. My chest even feels more congested than when I started typing this question. What do you guys think I have? I can't go to the doctor today because it's Sunday. The last thing I have to say is this weird symptom that no one else has as far as I know.... I have a weird smell in my nose sometimes, and I've only had that smell before when I had pneumonia. Post thoughts please.
