It could be that there are external forces at play. Maybe there are other characters or some kind of dark secret in the fanfiction lore that forces Edward to leave Bella while she's pregnant. For example, there could be a threat from a rival group that says they'll harm Bella and the baby if Edward stays, and he thinks leaving will draw the danger away from them.
She could be heartbroken. After all, she's pregnant and the person she loves has left her. She might feel abandoned and alone, crying a lot and wondering why Edward would do such a thing.
In such fanfiction scenarios, Bella's pregnancy while Edward is gone often sets the stage for intense character development. She might become stronger and more independent, or it could bring out hidden vulnerabilities. It also creates a lot of tension and anticipation about whether Edward will return and how things will unfold.
Well, it usually leads to a lot of drama and emotional turmoil for Bella. She's left alone to deal with the pregnancy and all the complications that come with it.
Bella might rely on her human friends at first. She could turn to Angela or Jessica for emotional support. They would help her with day - to - day tasks like grocery shopping and going to doctor appointments. Also, Charlie, her father, could play a big role. He might be initially shocked but would come around to support his daughter.
One possibility could be that Bella has to face the challenges of pregnancy alone. She might struggle with the physical and emotional changes while also dealing with the absence of Edward. The Cullen family could be in a dilemma about whether to support her or not, as Edward's departure might have left them with mixed feelings. And Bella could start to discover new powers or abilities within herself as she copes with the pregnancy, which could be a big part of the fanfiction plot.
The baby could also be a tool for character development. As Bella and Edward (if he comes back) interact with the unborn child, they might discover new aspects of their personalities. For example, Bella could become more nurturing than she was before, and Edward could become more accepting of the idea of a family, which was something he was hesitant about before.
A really interesting plot twist could be that Bella's pregnancy progresses at an extremely fast rate, and the baby has powers that allow it to communicate with Bella and Edward telepathically even before it's born. This causes them to reevaluate their relationship and what they thought they knew about vampires and half - vampire children.
One possible storyline could be that Edward leaves due to his fear of endangering Bella and the unborn child. He might think that his vampire nature could bring harm to them, so he decides to distance himself to keep them safe.
She might first be in shock. Then, she could turn to her friends like Jacob for support. Jacob, being protective, would likely try to help her in any way he can, whether it's providing for her basic needs or just being there to listen to her fears and concerns.
