In brief: Testing too soon

Main thing is timing-it takes time (up to 2 wks) for your urinary levels of HCG to get elevated enough to be detected.
Over-the-counter tests aren't always as sensitive as tests at your doctor's office, but even those usually take at least a few days after you're late to turn positive. Recheck 1-2 weeks later if you're late for your period & suspect you might be pregnant.
