Help!!First time lateness?

So I lost my virginity this weekend and me and my boyfriend were very smart about it. We used protection (he pulled out) and made sure it was on a day far from my ovulation (only a few days before my period was supposed to come one) I’ve been having cramps but my period still hasn’t come on. I’m only a day late and I know I’m probably being paranoid but did anyone experience a delay in they period after they had sex the first time??? Am I being paranoid??
