If I can go back and find this article, I will post it. Anyway Someone actually referred me to an article here on Medium explaining why humans have periods (as all mammals do not). It seems to be for the purposes of us naturally aborting a fetus that posed a threat to our lives. If the fetus begins requiring too many resources, or if something is off with it, apparently the body naturally aborts it. These we call miscarriages.
Anyway this goes back to my idea of women learning more about how their bodies work and controlling them from within. Apparently we already have a natural abort mechanism built into our biology — and that’s the entire purpose of a period, to flush anything out the uterus that doesn’t belong there. We could be our own natural birth control, if we learned more about these mechanisms within our own biology.
