Skipped 2 days of pill, period starts early

So I have a few more days before I was supposed to start the placebo week and get my period but I ran out of pills (the order had gotten messed up because I had an extra pack for times when I ran out and used that last cycle). Last pill was supposed to be Saturday but instead was Tuesday. I've had cramps all day and am now spotting. However I can finally get my pills now but is it worth taking for 2 more nights and then starting my period or should I just start my period now? I want to wait until next Sunday to start up again though because I don't want to mess up the day my period usually starts. Is it that bad to wait that long (besides risk of pregnancy, I know that)?
