A member asked:

I took plan b and got my period as expected but i only got it for 3 days when i usually get it for 5 days is that normal?

A doctor has provided 1 answer

It happens sometimes: 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.
