Am I supposed to have a “period” while on the pill?

Update******* I got it on day 4. I’ve been cramping a lot. I think I will stick to skipping the placebo pills😭

I’ve been on the combination pill for 4 months and I usually skip my period by not taking the placebo pills. I decided to not skip them this month and to take them. I’m on day 3 of the placebo pills and I’ve had no period or bleeding. Is that normal? I take them almost perfect every day. Sometimes I take them like an hour or two late but that all. Also negative pregnancy test.
