Menstrual Cycle: In this case pregnancy is unlikely as females do not ovulate during the bleeding portion of the menstrual cycle but usually about day 14 in a regular 28 day cycle. With the addition of Plan B and repeat bleed shortly after taking it would make implantation of a fertilized egg would have been very difficult.
