Unlikely: Sounds most like a cold or sinus infection. The flu, specifically influenza, has high fever, headache and body aches, and a severe cough. It is more like a pneumonia. There is a quick test for influenza that can be done by your physician. Influenza most commonly occurs between november and march.

Possibly: This may be the flu. It can also be any number of viral illnesses. If it continues seek the advice of you physician.
