Am I ok?

Ok I had sex for the first time today. My last period was 11 days ago and after we were done having sex he realized his condom tore. The tear wasn't near the tip it was on the side. But I'm not sure if he came inside of me or not because I feel he did it was probably only a tiny bit since the condom tore on the side. I took Plan B 6 hours afterwards. Should I be ok or should I worry?
