Someone help

So the last time I had sex was in April and I had to take the morning after pill because the Condom broke and he came inside me. I didn’t get pregnant and I got my period. My period is now more than a week late and I’m stressing because I’ve heard stories about people getting pregnant when they haven’t had sex in months. Idk if I’m just being stupid but can someone just give me some closure ahhhh. My period is never irregular as well.
