Birth Control Help

So I am taking the pill and the beginning of the week/package is always on a Monday. During the last week of the months pills I ended up accidentally skipping a day, I took two the next day as instructed and it was fine from there. A couple days later I had sex and then it was time to start my period. I’m about five days late from my period, could it be because I messed up the pills or should I wait a couple more days and check?
