Birth control and period

I’m 8wPP and I started taking BC pills at 6wPP. My birth control is the one that gives me a period monthly. I still have a week and half left of my pills until I get to the sugar pills. Today I started bleeding though. No cramping or anything that makes me think this is a period. The blood is bright red. Not a lot, but more than spotting. Is this my period or something else?
