Pregnant?

Alright so, 2 Saturday’s ago, the day my fertile window ended, I had sex with a guy. And he opened the condom with his teeth...which kind of scared me.....he came in the condom and we were done, we didn’t check the condom with water or anything. Then, 3 days later, I had sex with a different guy. We checked the condom with water and there weren’t any holes...now, it is 2 days before my period and I’m not having any symptoms. Should I be worried?
