morning after pill late period

imagine that it’s wednesday and i am supposed to get my period on friday. so, on wednesday my boy friend and i had sex without a condom, he DID NOT cum inside of me. but, later that night we were talking about what we would do if we ever got pregnant and it got me worried. just the idea of having sex without a condom was enough to scare me. then on friday i didn’t get my period. so on saturday, when i still hadn’t gotten my period, he bought me the morning after pill and i took it. now it’s sunday, i felt all the side effects off the pill, but i havent gotten my period. what does it mean?? please help, i am scared...
