Can you get pregnant after your period on the 2nd and had sex on the 3rd and 5th and 6th, on the 5th, you use postunor2, can you still be pregnant?

Preg. unlikely, but: 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.
