That a female "menstruation cycle" can change when living in and being around more the one female? Do all of the females who live and be around more then one female all get on the same "menstruation cycle" if the there is a change in their cycle? is there one type of a alpha female who sets the new cycle? I understand this is not any conscious thing that the females do knowingly. How does all of this happen and go down? I am not trying to be some meat head and fool by asking these questions it is all about curiosity for me. It amazes me that this could or does happen? The human body is something else. I hope you could shed some light on this for me please?
