It might be a relatively unknown author who is just starting out in the world of fanfiction writing. They might have been inspired by other magical pregnancy storylines in different fandoms and decided to create their own version within the Harry Potter universe, using Hermione as the central character.
There could be many amateur fanfic authors out there who might have written such a story. It's hard to pinpoint just one. There are numerous fanfiction platforms where people with a creative streak and a love for the Harry Potter universe might have come up with this idea.
Well, it could involve a spell gone wrong during some magical experiment. Maybe a misfired charm that had unforeseen consequences on Hermione's body, leading to the pregnancy. The story might then focus on how she copes with this unexpected situation, both physically and emotionally.
It could be Ron. Since they have a relationship in the original story, it's a very likely option. Their relationship could be further developed as they face the new chapter of becoming parents together.
One possibility could be Ron. They have a long - standing relationship in the original series, so it would be a natural choice. Their relationship has its ups and downs, and a pregnancy could be a big turning point for them.
It could be Ron. Maybe they had a falling out or some sort of misunderstanding during their relationship, and Hermione runs away when she discovers she's pregnant. Another possibility is that it's a new character, someone she met during one of her adventures or studies. This new character could be from a different magical culture, and their relationship was a secret.
Perhaps the spell gone wrong could cause them to be trapped in a time - loop. They keep repeating the same day over and over again. As they work together to break the loop, they start to understand each other better. Draco realizes Hermione's intelligence and determination, and Hermione sees that Draco isn't just a mean Slytherin. This could lead to a new - found respect between them.
There could be many amateur fanfiction writers out there who might have come up with this idea. It could be someone who really loves Hermione's character and wanted to explore a more supernatural side of the Harry Potter universe with her in it.
Perhaps it's a writer who loves Hermione as a character and wanted to give her a different kind of adventure. They might have created this werewolf - Hermione dynamic to show Hermione's ability to handle unusual and potentially dangerous situations in a new way. Without more information, it's impossible to determine the exact author.
One possible plot could be the challenges they face. Maybe Hermione is initially scared and conflicted about the pregnancy as Fenrir is a complex and somewhat dangerous character. Society might not accept their union, so they have to deal with secrecy and the judgment of others.
One possible story could be that it's an alternate universe where Hermione and James are paired. Maybe they fall in love unexpectedly. The pregnancy could bring out a whole new side of their relationship. It could be a story full of challenges as they face the wizarding world's reactions to their union and the upcoming baby.
It could be that in the fanfiction world, Hermione was the victim of a spell gone wrong. This spell could have made her pregnant and also somehow cut her off from her usual support system, leaving her alone. Or perhaps she made a choice to distance herself from others because she didn't want to endanger them while she was dealing with this unexpected pregnancy.
