3 weeks after sex: 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.

You are not pregnant: None of your symptoms represent any normal or common early pregnancy. You bled. Even if it was lighter than usual this means you are not pregnant.
