Had sex with my boyfriend. was a virgin so he used withdrawal method and i took postinor two tablets at once after 6 hours.i started bleeding immediately after sex but it stopped. after postinor pills i saw a discharge in my pants can i get pregnant?

Yes, but not likely: 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.

Congratulations: Welcome on this important milestone. I am glad that you have this relationship, and that you took precautions against pregnancy. You are very unlikely to become pregnant from this. The withdrawal method is famously ineffective, as well as not much fun, and I hope you will use more reliable protection; your physician can help. Human love is never perfect but I hope you will treasure this time.
