Firstly, postinor is an emergency contraceptive
medicine. These are only 75% effective. So there is a 25% chance of failure. Considering you had sexual contact twice within a 24 hour period and you are in the fertile period of your cycle, there is a high chance of pregnancy
. I suggest that you do not take any more self medication
and meet a doctor. Conduct a simple urine pregnancy test to confirm your pregnancy.
But please meet a doctor. Wish you good health.
