Good day, is there any chance of pregnancy if i had unprotected sex two days after the ending of my period. an hour after i took p2 pills as described?

About E.C. pills...: Plan B, Postinor 2, or other emergency contraceptive pills can alter the menstrual-type bleeding for the cycle in which pills are taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because emergency contraceptive pills work most of the time, but not all the time... meaning there is just a small chance of pregnancy.
