I have the flu, started yesterday and my symptoms got worse today. I could barely get out of bed this morning so I went to see my doctor today at 3:30. After sticking a q-tip up both nostrils into the nasal cavity which huuurt, their test said yes I had the flu. I caught it within the 48 hour period, so I can take the medication but it will still be with me for 5-7 days. Here is a site that lists the symptoms of the flu http://www.flufacts.com/symptoms/ so if you get any of the, be sure to go to your doctor and catch it before it gets worse. You may have it longer than a week.
