Question?

So this month I skipped my placebo pills and went straight to the next pack (which I got okayed from my doctor to do every once in a while) because it is my boyfriends birthday tomorrow and let's be real, I don't want to be on my period for that. My question is, I'm still having period symptoms like breast tenderness, and really bad cramps. And today is the day I would've started my period if I hadn't gone to the next pack, is this normal or should I be ready for my period even though I shouldn't get it?
