Bleeding when period is not expected.

Lily-Anne
This morning when I wiped I was bleeding like I would if I was on my period. 
It was more stretchy and more clotty than a normal period, but there was blood no less. 
My period isn't due for another week and a half, as I haven't yet finished my pill strip yet. 
An hour or two later I wipe, and there is nothing. Nothing at all, but I'm still having uncomfortable period pains. 
Could this just be my hormones acting up as this is only my second month back on the pill?
