Late period

I had protected sex with a condom for the first time ever this month. I lost my virginity. I am now late with my period 4 days. It could be stress since I do have a lot going on this month.. but I'm not sure. Also, I've heard of other girls that had gotten their periods late after their first times.. I guess I'm just asking if this is normal? Im taking a pregnancy test in the morning.. please send help! ♥️ xoxo
