pregnancy paranoia???

okay so i had sex with my boyfriend two weeks ago (during my fertile window :/) and it was both of our first times. we used a condom and i’m pretty sure we used it right but now i’m paranoid that i’m pregnant? especially because my period was due yesterday but it hasn’t come and i’ve been pretty regular since i first started getting periods.

i’m going to buy a pregnancy test tomorrow after school just to be sure but i feel like i’m just going to worried every month before my period and i really don’t want my brain to ruin having sex in the future by worrying about pregnancy.

does anyone have any advice on how to not obsess over when my period will come??
