when a group of women live together or spend a lot of time together their monthly cycles tend to sync up.

or

when another woman on her period causes you to start your period early

(since women's cycles are often linked with the moon, it's not hard to make the leap from women's time of the month to werewolves and their monthly change)

In a wolf pack, there's usually one girl. This girl is just like everyone else, and seen as the sister to most. She's off limits unless established by bros in the group. Excellent wingman to everyone, very attentive thinker.
"So should I date Tracy? We hit it off last night."
"Nah dude, she's a she wolf."
