Is this Implantation Blood? (PICS)

[Babyce235322]

I'm 13DPO. And I took a pregnancy test today at 7:30, it was negative. Then I had mild cramping around 12/1pm. Just went to use the bathroom 10 mins ago (7pm) and saw this.. Not a period because I was on the Depo for a year I was due for my last shot June or July ain't never went to go get it, so that's out the question.
