Mini pill and bleeding?

So I’ve been on the mini pill and I ovulated 3 days ago (I know cuz I look at my CM) anyways I missed a couple days and now I’m bleeding. I know it’s not implantation bleeding because it’s to soon. I did have sex 4 days ago though. Is it my actual period or is it withdrawal bleeding? Meaning it’s a “fake” period? I’m not supposed to start my period for another 2 weeks.
