In a fanfiction, Bella could be on her period while on a camping trip with her friends. She has limited supplies and has to be resourceful. She might have to deal with the embarrassment of asking her male friends if they have any spare clean clothes she could use in case of an emergency. This situation could lead to some really interesting character interactions and growth.
Perhaps a fanfiction where Bella is on her period and she's at a special event. She has to endure the pain and inconvenience while still trying to participate fully. Maybe she's at a dance competition and she's using all her willpower not to let her physical state affect her performance, and her friends start to notice that something is off with her.
One possible plot could be Bella struggling to hide her discomfort during her period while dealing with the usual vampire - human drama in Forks. Maybe she's worried about Edward smelling the blood and it adding an extra layer of tension to their relationship.

A plot could revolve around Sakura's discovery of new ways to manage her period while in a world full of magic or special powers. For example, she might find a magical herb that eases the cramps.

Perhaps it focuses on Eleven's own journey of self - discovery during this time. She might feel different and start to explore more about her femininity. It could also show how she copes with the hormonal changes and the emotions that come with getting her period.
It could be about how Temari deals with the physical and emotional changes. Maybe she tries to hide it at first, fearing it might affect her ninja duties.
In a 'Mulan Gets Her Period' fanfiction, perhaps the story could focus on how the other female soldiers in the camp, if there are any, support Mulan.

It could be about Tenten dealing with the new experience of getting her period while also trying to maintain her ninja training. Maybe she has to hide it from her male teammates at first out of embarrassment.
