...a New York Times report that suggests that “morning-after pills” probably don’t prevent fertilized eggs from implanting in a woman’s uterus.

I am not sure about this, but I believe one of those pills causes a woman to have her menstrual cycle spontaneously. Did that prevent the fertilized egg from implanting? Did the egg even have a chance to fertilize? Only God knows. Only thing we know is the woman got her period.
