Am I pregnant? Please send help :)

Okay so I didn’t take my birth control at all last month because I couldn’t get it and I was out (long story) anyways, on the day I was supposed to start my period, me and my boyfriend had sex, he did not finish it me, but now my period is almost a week late. I know I shouldn’t be stressing but I really am. Don’t know whether my period is late from not taking my bc or because I’m pregnant. Please give me any advice y’all have!
