My period should come the 3 of sept 2010 now is the 5 and I don't have any simtom of pregnancy, everything is normal no nausea, vomitin tender neple notin at all. I'm worried if I'm pregnant or not.

If you think there is a chance of pregnancy try a test. It is not uncommon to be off a few days here and there, so it may just show up late this month.
