Period or pregnancy?

i’m really in need of advice regarding periods/pregnancy right now!

on the 14th my bf and i had intercourse and unfortunately the condom broke (this was also my most fertile day of ovulation). i’ve always struggled with irregular periods (they either start early or late - never on time) and i was supposed to start on the 30th. i’ve had all my period symptoms just no period. i’ve also been SUPER stressed recently and sick with COVID for about two weeks now so i genuinely can’t tell if my period is just delayed or if i AM pregnant.

i cant get a pregnancy test right now because then our families would find out and if i’m not pregnant, i’d rather not get them involved yet. should i be worried yet or should i give it time?
