What does this mean........?

I feel really, really sick, like my head hurts and I feel sorta dizzy and dazzed. And I checked with like three different thermometers and all said i was like 97.6, 7, or 8. So I obviously don't have a fever but isn't like your normal tempature usually like 98.5 or 6?? I'm just confused because I feel so sick and I thought the normal tempature was like 98.5.....so um, whats this mean?
