Am I in the early stages of the Swine Flu (H1N1)?

I am normally healthy in school from the beginning of the day, after Period 1 I go to HomeRoom, my clmate claims he has the Swine Flu, and hes constantly coughing, so I try to cover my nose / mouth but he accidentally coughed on me, and I think I contracted it. Come Period 4 Im coughing like a mad house...I get a cough drop, it cools down...It comes back once the cough drop is gone...I went home for lunch (After Period 4), I'm still coughing crazily, when I was leaving to return to school my cough got really bad and I start throwing up all over...I decided to stay home the rest of the day and sleep...Now around 5:00PMish, I get a very bad sore throat and everything I eat / drink tastes very bad...I also keep getting random migraines, so...do you think I have it? And what should I do?
