Well, perhaps in the fanfiction, Sakura discovers she's pregnant right after Sasuke leaves. She initially feels betrayed and hurt. But then she realizes she has to be strong for the baby. She might start training the baby in her womb with her chakra, hoping it will inherit her strength. And she could also write letters to Sasuke, even if she doesn't send them, just to express her feelings.
One possible plotline could be that Sakura decides to raise the child on her own. She focuses on her medical ninjutsu to provide for the baby. Another could be that she tries to find Sasuke again to make him take responsibility. Maybe she faces challenges from the village as a single mother, but her friends support her through it all.
A plotline might involve Sakura facing a lot of judgment from the village. But she stands strong and raises the child with the help of her friends like Naruto and Ino. They support her emotionally and sometimes even materially. As for Sasuke, he might be on a journey of self - discovery and when he hears about the pregnancy, he has to decide whether his path still lies away from Konoha and his family or if he should change his ways.
One possible plotline could be that they leave to seek a new form of power. Maybe they've discovered a threat that the Hidden Leaf isn't aware of, and they believe they can find a solution outside. Another could be that they're on a journey of self - discovery. Sakura has always been in Sasuke's shadow to some extent, and this could be her chance to truly find herself while being with him. Also, perhaps they leave due to some political unrest in Konoha that they don't want to be a part of.
Well, it could be that Sasuke and Sakura are on a journey when they find out about the pregnancy. They then have to find a safe place to stay. Along the way, they meet different people who either help or hinder them. Meanwhile, they are also having deep conversations about their relationship and what kind of parents they want to be. They might also be worried about passing on their ninja skills and the burdens that come with it to their child, and how they can raise the child in a more peaceful world.
One possible plotline could be that they are forced into a situation where they have to be together, and over time, feelings develop and Sakura gets pregnant. Another could be a magical or alternate universe situation where their relationship is different from the original Naruto story, leading to her pregnancy.
One possible plotline could be that Sakura is physically held by Sasuke against her will, and she struggles to break free while also dealing with her complex feelings for him. Maybe she's trying to understand his motives for holding her in such a way.
A possible plotline could be that they are both on a mission to rescue their kidnapped comrades. They have to work together, using their unique ninja skills. Female Sasuke with her lightning - fast attacks and Sakura with her super - strong punches.
In some fanfictions, it could be that Sakura is under a genjutsu (illusion technique). The genjutsu makes her act in ways that seem like she is cheating on Sasuke. She doesn't realize what she is doing until it's almost too late, and Sasuke has to figure out what is really going on to save their relationship.
One possible plotline could be Sasuke discovers he's pregnant while on a solo mission. He then has to figure out how to deal with this situation while also hiding it from his enemies. Another could be that it's the result of some sort of magic or experimental jutsu gone wrong. He then has to face the reactions of his friends and family, especially Naruto, who might be shocked but also supportive.
Perhaps Sasuke uses Sakura to get closer to some information. He might know that Sakura has connections or knowledge that can help him in his quest for revenge or for protecting the village. So he uses her in a strategic way while she is initially unaware of his motives. As the story progresses, their relationship could develop in complex ways.
In some fanfictions, the plot could start with Naruto and Fem Sasuke having a deep emotional connection that leads to a physical relationship resulting in pregnancy. Then, they might have to deal with the social implications within their respective clans. For example, the Uchiha clan might have certain expectations or reactions to Sasuke being pregnant outside of marriage. Naruto, on the other hand, might have to face the judgment of his friends like Sakura or Kakashi. The story could also revolve around how they plan for the future of their child, whether it's about training the child to be a great ninja or just providing a normal life away from the chaos of the ninja world.
