Pill help

I've been taking the pill for 4 months now at the same time everyday no problems. Though this week i've been a mess, this is my first week for my new pack (i had placebo last week) and i took my pill two hours late on monday, got back on schedule, and one hour late on saturday. Saturday night my boyfriend and i had sex, while he didn't cum inside me, he might as well have because he came on my vagina, waited a few minutes and stuck it back inside me. Im pretty scared of what my chances are that i might get pregnant?
