Im 28 i have always had normal periods it was due on the 9th of July never came ive taken preg tests every day since all tests were negative with very light spotting today could i be pregnant?

Periods can also be late due to stress (work, relationship), weight gain/loss, change in lifestyle and medications.

To be sure, take a pregnancy test at your doctor's office. A simple blood test can also determine if you are pregnant or not.
