You can try looking on popular fanfiction websites such as Fanfiction.net or Archive of Our Own (AO3). Just use the search bar on those sites and type in 'Dominique Weasley pregnant' and you should get a list of relevant fanfictions.
One common theme could be family reactions. Since she is a Weasley, her large family's response to her pregnancy would be an interesting aspect to explore. For example, how her parents, siblings, and extended family members deal with the news.
One common theme is adventure. They might go on magical quests together, exploring new parts of the wizarding world. Another theme could be romance, as they are often paired in these fanfictions. There's also the theme of friendship development, especially if the story is set in Hogwarts or other wizarding school - like settings.
Well, of course, Dominique Weasley herself can be considered the best character in many of these fanfictions. Since the stories are often centered around her, she is the one who drives the plot forward with her actions, decisions, and relationships.
Well, I've read a fanfiction where Dominique Weasley gets involved in a time - travel adventure. She accidentally travels back in time and has to find a way to get back to her own time without changing the course of history. It's really exciting as it weaves in elements from different eras of the Harry Potter universe. And then there's the fanfiction that depicts her as a brilliant student who uncovers a long - lost spell that has the potential to change the wizarding world, but she has to decide if using it is the right thing to do.
Another option is to follow some Harry Potter fanfiction writers on social media platforms like Twitter. They might announce when they've written a new story involving Dominique Weasley and James Potter. Additionally, Wattpad could also be a place to look, although it has a wide range of content quality. But with some patience and searching, you could find some interesting fanfictions about them.
One idea could be that Ginny discovers she's pregnant during a time of relative peace in the wizarding world. She might initially be worried about how Harry will react, but he is overjoyed. As the pregnancy progresses, Ginny could start to train her unborn child in magic in a very gentle way, like whispering spells near her belly. Lily could grow up to be a powerful witch with unique abilities, perhaps having a special connection to the magical creatures in the Forbidden Forest due to Ginny's own experiences there.
One possible scenario in this kind of fanfiction could be that Ginny discovers she's pregnant at a very inconvenient time. For example, there might be some dark forces rising again in the wizarding world, and she fears for the safety of her child. So she decides to run away to a secluded place, perhaps a small cottage in the countryside that she discovers through some old family connections. This would also give the author a chance to explore Ginny's maternal instincts and her ability to fend for herself.
A possible plot could be that Ginny is pregnant and Snape, as headmaster, is trying to keep it a secret from the wizarding community. He fears that if the news gets out, it could put Ginny and the baby in danger. So he arranges for Ginny to stay in a secluded part of Hogwarts. Meanwhile, Ginny is not happy about being cooped up and tries to find ways to still be involved in the wizarding world while protecting her unborn child. This creates a lot of tension and interesting interactions between Ginny and Snape.
One possible plotline could be the family's reaction. The Weasley family is large and close - knit, so they would likely be very excited and supportive. There could be scenes of them preparing for the new baby, like knitting baby clothes or setting up a nursery. Another plotline might involve Audrey dealing with the physical and emotional changes of pregnancy while also managing her daily life in the wizarding world.
