Help!!!!

I've had unprotected sex 10 times this month with my boyfriend and I'm really scared I'm gonna get pregnant. My period isn't till next month but I'm still scared. He didn't pull out at all either. I am on the patch but one fell off when I was swimming so I won't have to put on next week so I'm gonna go two weeks without it. Do you think there's any chance that I could be pregnant and just won't know till my period comes cause I'm skipping a week on the patch? And I know having unprotected sex was dumb.
