condom broke

PLEASE HELP 😭 yesterday my bf and i had sex, but the condom ended up breaking. Immediately after, we drove down to the nearest pharmacy and I took an emergency contraceptive pill within the first 30min of knowing the condom broke, but i’m still scared i’m going to get pregnant. According to my period tracker app, my next period is supposed to start in 2 or 3 days, and it says i have low chances of pregnancy but i’m still panicking. Is there anything else i can do to prevent the possibility of pregnancy? My boyfriend and I are in our very early 20’s and are still in University, not ready to have a baby.
