Pregnant?

Melani
So i recently had sex with my boyfriend on valentines day and we found out last minute THE CONDOM BROKE. now we are both in our 20s but i still took the pill the day after. Now i was supposed to get my period on the 15th of february and it obviously didnt come but its about to be a week since ive taken the pill. How long do i have to wait before i know if the pill worked or not?
