Took Plan B pill and started bleeding a week after (today). Had my period like 10 days ago. Why did this happen?

In brief: It happens

Taking Plan B or other emergency contraception pills can alter the timing or the quality of the current menstrual cycle bleeding and perhaps the upcoming cycle.
One should check a urine pregnancy 3 weeks after taking Plan B, because Plan B works most of the time but not all of the time.
