A member asked:

If i took the plan b pill the same day i had unprotected sex could it off failed? been nauseous and cramping

A doctor has provided 1 answer

Usually works, but: Plan B can alter the menstrual-type bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home urine pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time.
