I had my period on 09th june.we didn't sex.we did dry hump.i took postinor 2 after 6hrs on 13th.period hasn't come yet.i saw white clotting discharge.

It happens sometimes: Plan B, Postinor 2, and other brands of emergency contraceptive pills can alter the menstrual cycle for the cycle in which Plan B or Postinor 2 was taken, and sometimes the next month's 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. That said, no sex and no sperm means no baby.
