Spotting

Hi everyone so I had my period on the 10th last month and was expecting it soon. I started my period on the 7th this month and figured it was my period.... But it was very light & didn't seem much like a period I had no cramps or back pain like I usually do... & I only bled for about 2 days my period seemed a little darker than usual... Does anyone know if it was in fact my period, or spotting? Could this be an early sign of pregnancy?
