my period is late 😳

so earlier this month i missed my pill several times then i somehow got a day ahead on it. me and my boyfriend have only had sex maybe 2 or 3 times this whole month mainly bc i wasn’t sure how effective my pill would be but he doesn’t go inside of me. That’s the first time i’ve messed up so much on my pill and this is also the first time i’ve been late on my period since i started the pill. I’m stressing out that i am pregnant.. should i be worried?!!
