Pregnancy scare: If you have taken Postinor-2 within 72 hours after intercourse you will not get pregnant. This medication is high dose Progesterone which causes the uterine lining to shed within 24 hours, preventing implantation of a fertilized egg. You will have 3-4 days of bleeding and then your cycle should reset. Consider your first day of bleeding as Day 1 of your cycle, and expect menses in a month.
