Do I have the Swine Flu or regular Flu?

The first day I got sick(Thursday) I had a severe sore throat and a very runny nose, it was the worst day. On Friday I still had a mild sore throat but my sinuses were very sore too. On Saturday my throat was just a little sore and I kept coughing. On Sunday I had a pretty bad migrain. Today I still have sensitivity to light and sound and I'm feeling loss of appetite and nauseous. I also cannot hear out of one of my ears. What is wrong with me? And I have been exposed to the Swine Flu in my school, about 6 of my close friends have it. Should I see a doctor? I don't like going to the doctor AT ALL, so is it really an emergency?
