A member asked:

Last period i took planb in the first 3days of it, period stopped due to stress i belive, and is now 20days ahead of schedule. should i be concerned?

Some thoughts...: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. A woman 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.
