Menstruation refers to the rupturing of deposited egg cell in the uterine wall this egg when fully matured without the presence of male cell there will be no possibility of pregnancy.

how is this thing related: pregnancy only occur when an egg cell and male cell meets at the right time.

what to avoid: avoid the number 10. the tenth day after menstruation the female egg cell is release and deposited to uterine wall waiting for the male hormone to fertilize her. it will be active until the whole ten days after the release the most dangerous off course is the day fourteen coz the vagina provide so much liquid for your hormone to swim on.

why 9 is safe: because the first nine days including menstruation there will be no egg cell to fertilize and the other nine the egg cell matured already and there will be no possibility of being fertilize because rupturing of the egg already commence by then.
