am i pregnant???

okay so super tmi and this might be kinda long... but basically, i am on birth control right now and i have been for the past 3 years. to play it safe, every time i’ve ever been came in i’ve taken a plan b afterwards. on june 15th, 2020, my boyfriend came in me and has done so probably about 5 times since then. i didn’t get a plan b after any of those times because it’s highkey expensive lol. i take my birth control within a 2-4 hour window every night and i’ve read mixed stuff about whether you have to take it at the same time or not for it to be effective. i’m really scared and i don’t know what my chances are right now that i could be pregnant... i’m supposed to get my period in 12 days but in 5 days that’ll be 2 weeks from when he first came in me. should i take a test? are the chances high that i’m pregnant?
