Answer:
The stages of the moon
Explanation:
The term menstruation is related to the moon stages. Because of their coincidence in occurrence and in their duration time, people used to associate the feminine cycle to the moon cycle.
It is commonly said that the ovulation stage coincides with the full moon stage. In the same way, menstruation occurs when there is a new moon.
What really occurs is that the feminine period might or might not coincides with the moon cycle, and depends on each woman. But this is not a strict rule.
