Am i just paranoid?

Weeks back me and boyfriend kind had sex idk literally he put the tip in before i told him stop. We used a condom and i looked at if after we were done just to make sure it didnt pop or to see if it was cum in it but there was nothing. My period is a day late and i really hate that because i always thing im gonna magically be pregnant 🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️
