Pregnant or period coming?

Hi everyone so I was on bc pills for a month. I stopped it after the month. My period is now 8 days late. I've been cramping for atleast over a week on and off. And now the past couple days I am very emotional. Crying alot. Is it possible to get pregnant while taking the pill? Or is my period just super late? I've never missed a period and I'm always on time.
