Well, a common storyline could be about the reactions of their friends and family. Hermione might be super helpful, researching all about wizarding pregnancies and giving Ginny advice. Ron could be a bit clumsy at first but then become really protective. And the Weasley family as a whole would be overjoyed, with Molly Weasley knitting tiny sweaters and baby blankets for the new Potter addition.
Another storyline could involve the reactions of their friends. Hermione and Ron might be there to support Ginny throughout her pregnancy. There could be a lot of scenes of them sharing their experiences and knowledge about having a baby, adding a touch of friendship and camaraderie to the story.
In some fanfictions, there is a plotline about how their friends and family react. Ron might be his usual bumbling self but also very excited. Hermione could be the super organized friend who helps Ginny with all the preparations. And then there could be a plotline where they have to protect Ginny and the unborn baby from some dark forces that are still lurking in the wizarding world, fearing the power the Potter child might possess in the future.
A storyline where they are mentoring young wizards and witches at Hogwarts. Ginny, with her skills on the Quidditch pitch, could be coaching the team, and Harry could be teaching Defense Against the Dark Arts in a more practical and hands - on way. They would be passing on their knowledge and experiences to the next generation.
A possible plotline is that Ginny discovers she has some unique magical abilities during her pregnancy. These abilities could be related to protecting the unborn child or even sensing future threats. Harry would be both amazed and a bit worried as they try to understand these new powers. Another plotline could be that they decide to go into hiding during the pregnancy to avoid any dark forces that might target their child, similar to what Harry's parents did.
Well, some fanfictions might have a storyline where Ginny and Harry get separated due to some dark magic, and Jenny, who has some special powers, helps bring them back together. It could involve a journey through different magical realms. Or perhaps a story where Ginny, Harry, and Jenny all participate in a magical tournament that has some unforeseen and dangerous twists. Some fanfictions also explore what would happen if Ginny, Harry, and Jenny time - travel and interact with the founders of Hogwarts.
One possible storyline is that the Potter Manor is under attack by a new dark force. Harry and Ginny have to defend it using their skills and the help of their friends. Another could be that they are renovating the manor and discover some long - lost family secrets during the process.
Also, members of the Weasley family like Molly and Arthur Weasley are likely to be key characters. Molly would be all excited and involved in the pregnancy, giving Ginny all sorts of motherly advice and care. Arthur might be interested in how magic could be involved in the development of the baby, as he is always fascinated by the wizarding world's wonders.
One interesting fanfiction could be 'Ginny's Hidden Adventures'. In this, Ginny might go on a secret quest while Harry is away on Auror business. It could show her as a strong and independent witch, using her skills to solve mysteries in the wizarding world.
The support system of their friends is also a frequent theme. As I mentioned before, Hermione and Ron play important roles. Their reactions and help add a sense of community to the story. And often, there's a theme of facing new challenges. Ginny and Harry have to figure out how to balance their responsibilities as parents - to - be with their duties in the wizarding world.
A wizarding - only island would be an interesting setting. It could be filled with unique magical plants and animals. Harry and Ginny could spend their days cataloging the new species they find and their nights under a sky full of magical constellations.
