In brief: Typical with Plan B

Plan b essentially disrupts the normal menstrual cycle by blocking or delaying ovulation.
That it is how it works and why it is so different than a medical abortion. Irregular bleeding after taking Plan B is not rare. Always check a pregnancy test after using Plan B and see a doctor to start a better form of birth control.
