Do I have the Swine flu? Or when/should I get tested?

I have been having mild flu symptoms the past few days. 2 days ago my upper legs ached SO bad I could barely get up the stairs. I puked numerous times last night and had a horrible migraine. I have been fighting a mild sore throat and running nose off and on. I have a mild fever currently and still feel somewhat nausea. Should I get checked for the Swine flu? I would like to avoid doing so if not needed. How bad should my symptoms get before I get checked?
