One idea could be that Felix and Bella face challenges during the pregnancy. Maybe they have to deal with family reactions that are not all positive. Some family members might be worried about their financial situation or their young age.
Another possibility is a story where Felix and Bella are really excited about the pregnancy. They start preparing the nursery right away, painting it with soft colors and filling it with cute baby stuff. They could also be going to pregnancy classes together, learning about how to take care of the baby and themselves during this time.
A more dramatic fanfiction could involve Bella having some health issues during the pregnancy. Felix then has to step up and be extra supportive. He takes on more responsibilities around the house, like cooking healthy meals for Bella and making sure she gets enough rest. They also have to visit the doctor more frequently, which causes some stress but also brings them closer together.
To develop the story, start with their reaction when they find out about the pregnancy. Are they shocked, happy, or scared? Then, think about how their relationship changes. Maybe they become more protective of each other.
One plot idea could be that Felix, instead of being a villain, becomes Bella's secret protector in the Twilight world. He might sense some unique power within her that even the Cullens are unaware of. This could lead to a series of adventures where they have to hide their alliance from both the Volturi and the Cullens.
One idea could be that Bella has a brief encounter with someone before arriving in Forks and discovers she's pregnant. She then has to deal with the shock and the secrecy while also starting a new life in Forks. Maybe she's worried about how the townspeople will react and how it will affect her future relationship with Edward, if she still meets him in this scenario.
One possible title could be 'Bella's Miracle: Pregnant with Edward's Baby'.
One idea could be that Bella has to face the challenges of being a single mother in the vampire - human world. She might struggle to keep her baby safe from the Volturi.
The fanfiction could also focus on Bella's character development as Felix's sister. She might have her own dreams and goals, but at the same time, she always puts Felix first. For instance, if Felix gets into trouble with some other characters, Bella could use her charm or intelligence to get him out of it. It could be a story about loyalty, family, and growing up together in a fictional universe.
Well, a possible plot for a Paul and Bella pregnant fanfiction could involve them going on a journey to find a safe place for the baby. Since they might be in a world full of danger or just a place where they don't feel completely secure. Along the way, they meet new friends who help them and teach them things about parenting. Or perhaps, the pregnancy is a result of some kind of magic or fate, and they have to figure out what that means for their future and the future of their child. They could also face a villain who wants to harm the baby for some reason.
Love and destiny are common. Since they are soulmates, the idea of being fated to be together is often explored.
