Postinor 2 can be 95 percent effective in preventing a pregnancy, if taken in the first 24 hours, and 89 percent effective up to 72 hours. Its ability to prevent a pregnancy decreases over time, especially after 72 hours.
If you never took the second pill, its effectiveness may be decreased. You could ask your gynecologist. If you do not start your period within 3 weeks of taking the pill, you should test for pregnancy.
