HELP!!!!!

So my bf and I had sex (if you could even call it that). He used a condom and we only did it for about five minutes because I got paranoid and scared. He didn't orgasm. Now my period is late I think (I'm not the most regular person). But the last few times it was pretty regular. I'm scared and I don't know if I should be worried or not. Do you guys have advice for me?
