Maybe the period: Plan B can alter the menstrual symptoms for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time. Also, one should be sure to have a Plan A (reliable birth control method for ongoing contraception), so that Plan B will not be needed again.
