Sex scared hole in shaft

My and my boyfriend had sex for the first time. After the third time of having sex that night. We found a small pin sized hole half way down the shaft more towards the base of the penis then the head. He also pulled out before he came. As wel as glo said I was at a three percent chance risk of pregnancy. And hour after I decided not to take the risk and went and took the morning after pill. And I'm worried? Help?
