could this work?

I'm a little concerned that I'm pregnant. But I had a thought. A couple of months ago, I missed a pill, and my body was like "AHHHH GOTTA START A PERIOD" when it wasn't time. Clearly then I wasn't pregnant. But I was thinking. And this is just a thought, I won't do it if it's unsafe, I'm just curious.  If I miss a pill on purpose and double up the next day, do you think that the blood that I bleed be an indication that I'm not pregnant? Would that be my period?
