Could this be implantation bleeding (little tmi)

An hour ago I had period like cramps and thought to myself. I'm gonna get my period . So I went to the bathroom like 5 min ago . And I was peeing . And when I looked at my panties . And I had that really white thick cervical mucus which I've had for about a week. And when I wiped there was slight pink blood. And little tissue flakes in the toilet not clots . And I just went and checked now to see if I was bleeding any more . And now it's brown in color . Hmm my period not due for a few more days . I go for my pregnancy test tuesday . What do you ladies think ?
