Kimmy, that's a strange story.


I certainly agree, taking pills isn't exactly natural, but neither is having 400 periods in a life time! (low estimate)

In a "natural" state, women got pregnant and nursed their babies as long as they could, easily for 6 years per child. This naturally spaced out pregnancies and kept them amenorrheic. (read bushman ethnologies if you want to know more about this)
The average woman had 3 kids, spaced 6 years apart. Of course if they lost a child, they would start cycling again, and get pregnant again. But the end result was not very many periods at all.
