Pregnant on bc?

Me and my boyfriend had sex & he came in me, im on the pill and a lot of the times I usually take it my normal time, but that night I was an hour and 40 minutes late, is there a chance I could be pregnant? I was on the depo before, but now im a month and a half into my pills and I still haven’t started my period, I don’t know if it’s bc I was on depo, or if I could possibly be pregnant.
