A member asked:

I took 2 plan b pills a month ago. my period lasted a week when it usually lasts about 4 days. its been about 4 weeks since my period. am i pregnant?

A doctor has provided 1 answer

Probably not, but...: Plan B can alter the menstrual vaginal 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.
