Well, one possible plot could be that Rachel Berry discovers she's pregnant unexpectedly. She might initially be in shock and struggle with how to tell her friends and family. Maybe she's worried about how it will affect her career dreams. For example, if she has big Broadway aspirations, she could fear that the pregnancy will put a halt to her progress. She then has to deal with the reactions of those around her, like Finn who could be the father, and they have to decide together what to do about the future.
It could also be Jesse St. James. Given their past history and the complex relationship they've had, it's possible that in a fanfic he could be the father. Maybe they had a brief encounter that led to the pregnancy.
Finn could be involved if the fanfiction wants to explore a relationship with him as the possible father. He was an important part of Rachel's life in the original series, and his reaction to the news would be significant.
One possible plotline could be Rachel dealing with the reactions of her friends and family. They might be shocked at first but then come around to support her. For example, her friends could throw her a baby shower, which would be a really heartwarming part of the story.
One possible plot could be that Rachel and Finn are newlyweds. They find out about the pregnancy unexpectedly. At first, they're scared but then start to get excited. Finn might start working extra hours to save for the baby while Rachel has to deal with her Broadway dreams on hold. They could face some judgment from friends or family who think they're too young, but in the end, they come together stronger, ready to welcome their new family member.
Yes, there are quite a few. You can start by looking on fanfiction platforms like Archive of Our Own. Some stories might focus on how Rachel's autistic traits influence her relationships, like with her friends in Glee club. They could show how she experiences the world differently, adding a new depth to her character.
It could be an overzealous security guard. If Rachel was at a high - profile event and the security guard misinterpreted her actions as something threatening or against the rules, he could be the one to call the cops and get her arrested.
Archive of Our Own is a great place to start. It has a large collection of fanfics from various fandoms, including Glee. Just use the search function and type in 'Rachel Berry autistic' and you'll likely find some relevant stories.
In the fanfiction, Finn could face challenges in his career as he wants to be there for Rachel during the pregnancy. He might have to turn down some offers that require him to be away for long periods. Rachel, on the other hand, may initially think that the pregnancy is the end of her Broadway dreams. However, as time goes on, she could find ways to combine motherhood with her career. For example, she could start a musical project about pregnancy and motherhood, which could attract a whole new audience.
Honestly, without more context about who 'yoo rachel' is, it's difficult to know if there is a pregnant fanfic. If they are characters from a TV show, movie, or book series that has a large following, then there could potentially be a fanfic exploring such a plot. But if they are original or very obscure characters, it may not exist. You could also try reaching out to fans in relevant fan communities to ask if they've come across such a fanfic.
