Can plan b still affect my period if i'm over 165 pounds?

A doctor has provided 1 answer

Yes: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too, even if a woman is over 165 pounds. 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.
