Bleeding a week after period.

Kaitlyn
So my period ended a week ago. I just went to the bathroom and noticed im bleeding. Its not like a spotting bleeding either. Im 100% certain that im not pregnant, and i have never gotten a period this close and its 
Not normal for me to spot. 
For the past 6 months or so i have been having cramps all month long that intensify as my period gets closer.  What is this? What should i do? I mean obviously i should call my dr.
