Swine Flu

I woke up this morning with flu symptoms such as fever of 38 degrees, nasal congestion, headaches, sensitive throat.
I would hate to be in the public if I know I could have swine flu. How can I be sure that it's regular flu? My friends have been urging me to notify a doctor immediately. out of responsiblity to those around me.
I have not travelled to Mexico or anywhere and have not been in contact with anyone I know who has been in contact with swine flu other than travelling on buses, and the usual public places.
I would appreciate knowing if I should see a doctor ASAP or just relax .
