Tests are accurate: Taking Plan B or other emergency contraception pills can alter the timing or the quality of the current menstrual cycle and the upcoming cycle too. One should check a urine pregnancy three (3) weeks after taking Plan B, because Plan B works most of the time but not all of the time.
