Messed up period or what?? help.

So i had to stop taking my birth control for the month of February. i stopped taking it AFTER i started my last period in January. So i haven’t been on my birth control this month and i have not had sex, but i am 4 days late on my period. should i be worried?? TMI but the only thing i’ve done, as far as sexual goes, is masturbate after my boyfriend came in my hand, but it masturbated an hour later when it was completely dry👍🏼🤷🏽‍♀️

Also, i can’t find anything on google about my specific situation.
