Question unclear but: Irregular bleeding after taking a morning-after pill, like Plan B, is somewhat common. Some women get spotting or bleeding before the next period. Women may also have a heavier or lighter next period, or a period that is early or late. A urine pregnancy test can be done 3 weeks after taking a morning-after pill, to be sure the pill worked.
