If you develop chest tightness, difficulty breathing, swelling of lips, mouth, throat – call 911. Notify your GYN if your period is 7 or > days late.

About Postinor 2: Emergency contraceptive pills can alter the menstrual bleeding for the cycle in which the emergency contraceptive pills were taken, and sometimes the next 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.
