The likelihood that you are pregnant is extremely low. Use of Plan B can cause many different types of menstrual irregularities including the type of bleeding that you described. If you normally have 28 day cycles (from beginning of one period to the beginning of the next), your next period will probably come approximately 28 days after the beginning of the second episode of bleeding that you experienced. However, it could come earlier or later as well. Please remember that Plan B should not be used as a regular method of birth control as it is intended to be used for emergencies only. If you plan to continue to have sexual intercourse, please contact one of our offices for an appointment to start some type of regular birth control.
