Missed period after the pill?


So I started the birth control mainly because of my extremely painful periods you get it, but I came off of it after a week of taking it. It was making me super sad and crying all the time and made my periods lighter but more painful. Anyways, so I stopped taking it mid period, around the 19th September. I’m now five days late for my October (most recent) period. Me and my boyf haven’t had sex since cos I didn’t wanna jinx anything😂poor guy, but yeah. Someone tell me if it’s normal or what to do xxx
