For example, she could be on a mission and have to hide her condition from her teammates to avoid being seen as weak.
Another plot could be Sakura Haruno using her medical knowledge to deal with the symptoms of her period. She could be researching herbs or techniques to ease the pain and discomfort. This could also lead to her sharing this knowledge with other female ninjas in the village, starting a sort of women's health movement within the Naruto world.
Perhaps the fanfic could focus on how Sakura Haruno's friends react when they find out she's on her period.

Show her strength in dealing with it. She is a strong character, so depict her handling the physical and emotional aspects of being on her period with grace. You can also include how she takes care of herself, like making sure she gets enough rest and proper nutrition. It should be about her self - care and not just a plot device for drama.
The plot could center around Sakura's transformation into an Arrancar being a result of a powerful experiment gone wrong. As an Arrancar, she could discover new abilities she never had in the Naruto world, like the use of Cero.

And she would also have to figure out how her medical skills from the Naruto world could be applied in this new, more dangerous setting.

Maybe she forms an alliance with other superheroes or anti - heroes in this universe.
The main plot could be Sakura trying to break free from the predefined roles in her village. She might feel that being a 'ninja' and a 'healer' doesn't fully encompass who she is. So she starts to explore other aspects of herself, like her love for art or music that she has suppressed due to her ninja duties.
