Your sharepic is also quite misleading - yes, menstruation occurs approx. every 28 days, but the lunar month is also 29,5 days and we know of many calendar systems and ancient cultures that used lunar months. Which makes sense as moon phases are easy to observe and kind of align with the year. So that could be some stone age woman tracking her period, but it could also be a male priest tracking the moon.
