A member asked:

Hello dr. i'm experiencing some dark red-brown spotting. i took postinor 2 5 days back. could it be implantation bleeding or its just a side effect of?

A doctor has provided 1 answer

Very 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.
