Help my period is late !! Because of birth control pills?!

so i took birth control pills to start having sex with my boyfriend but we saw that we weren’t ready yet but i couldn’t stop it before ending the first placket so at the end of it the first placket i decided to stop taking them which means i took them for a month but sometimes when we slept together me and my boyfriend we have “sex” without penetration which means he ejaculates without penetration and i know that there’s a very small possibility that i would be pregnant if it was without penetration but my period isn’t here yet and it’s freaking me out cause i don’t wanna be pregnant...

And i have some symptoms like having a stomach ache sometimes and a feeling like if there’s some discharges coming plus brest soar...

so do you guys think that i might be pregnant or is it because of stopping the pills?
