sex and pill and period

so saturday was my last day of my period and my last pill i started over sunday, i had missed a placebo pill, i took it when i got home from school, i normally take my pill every morning at 6:30, does that affect anything? my bf and i had sex on saturday and as he pulled out the condom broke and he got cum in me. i’ve been on the pill for months. do you think there is any possibility i could be pregnant?
