Took plan b almost 2wks ago, 48hrs post-incident. experiencing some nausea & minor-severe cramping after spotting for almost a week. normal?

About Plan B...: Plan B can alter the menstrual bleeding 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. If cramps in the pelvis are "severe", a woman should call her Ob-Gyn doctor to see if an appointment is needed.
