Should I be worried ?

So me and my boyfriend are sexually active and the last 3 times we had sex the condom either broke or we didn’t use one the whole time. All 3 times he pulled out just as a safety measure but my period is a day late and it’s always on time. Should I be worried or should I just relax because a few of my friends said that having sex can mess up your period cycle sometimes. 🤷🏻‍♀️🤷🏻‍♀️
