Do I have swine flu (H1N1)?

I started feeling sick sunday morning, with a sore throat that quickly turned into a bad cough. My head and eyes ache, and my chest and back do too. I also have a very stuffed up nose and keep sneezing. I got sent home early from school today with a 102.4 fever, what are the chances this is swine flu? Also, I got the regular flu mist about 3 or 4 weeks ago and had symptoms from that.
