Shorter than not: taking it ! while the drug in plan b is out of the system in 2-3 days tops, it changes the entire cycles timing. This results in menstrual irregularity. Might take 1-2 Entire Menstrual Cycles to readjust.

3 days: I believe about 3 days, but everybody is different. The consequences of taking plan B can linger a bit longer as your body adjusts to the elimination.
