Looking Details On Morning After Pill

Hey Doc, i would like to know more about the morning after pill please. This is because my period came on the 1st/2nd April after which i had unprotected sex on the 10th April. After doing this i took the 1 of the 'postinor 2' right after and the other pill 12hrs later. Today is the 5th and i was curious as to if worked and approximately when my next period would come? Thanking you.
