Girlfriend had 2 postinor 2 pills at the same time in like 25th hour after unprotected sex and after 5 hours taking the pills shes complaining blood clot bleeding for 2 minutes and complaining a stomach ache like for periods. is she pregnant?

Hard to guess, 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.
