Well, it could be a story about the anticipation and joy they feel. Maybe it focuses on how they prepare for the arrival of their child, like setting up the nursery. Harry might be a bit nervous about being a father, but Ginny is there to reassure him.
In this fanfiction, it might show their relationship growing even stronger during Ginny's pregnancy. They could be reminiscing about their own childhoods and how they want to give Lily a better life. There might also be scenes where their friends, like Hermione and Ron, offer support and advice.
The story could explore the magical aspects of Ginny's pregnancy. Since they are in the wizarding world, there might be special potions or spells to ensure a healthy pregnancy. It could also delve into how they handle the public attention, as Harry is quite famous. They might want to keep their family life private, but still have to deal with the media in the wizarding world at times.
The story could develop with Ginny sharing her pregnancy news with her friends at Hogwarts. They could all be excited and start planning for the baby. For example, Ron might be a bit clumsy but still try to be a good uncle - to - be. As for Lily's future, she could grow up to be a brilliant student, following in her parents' footsteps. Maybe she discovers a new spell or a hidden magical talent.
One possible plot could be that the baby Lily shows signs of having extraordinary magical abilities from a very young age. Harry and Ginny are both proud yet a bit worried about how to guide her. Maybe she accidentally makes things levitate or changes the color of her nursery walls with her magic. They start to introduce her to the wizarding world gently, taking her to visit Hagrid at Hogwarts. And as she grows, they face challenges from the wizarding community who are either overly curious or a bit envious of the family's status.
Harry would likely develop more responsibility. He's already a hero, but now he has to be a father. Ginny would become more nurturing. As for Lily, in the womb, she could be shown as having a special connection to magic from the start.
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.
A new dark wizard could emerge in the wizarding world. This wizard might be jealous of Harry's fame and power and think that by getting to Lily, he can gain some sort of advantage. He could try to steal Lily's magic or use her to spread fear in the wizarding community.
One possibility is that Harry and Ginny could use a time - turning device to go back in time and meet James and Lily. They might share stories about Harry's life, and James and Lily could give their blessings to Harry and Ginny's relationship. Ginny could also learn some of Lily's magical tips.
One possible plot could be that through some time - traveling magic, James and Lily are brought to the future where they meet Harry and Ginny. They are amazed to see how much Harry has grown and the family he has created with Ginny. They share stories of the past and the challenges they faced, and James and Lily get to see the world they sacrificed so much for in a new light.
One scenario could be that they meet in a time - travel situation. Harry and Ginny could be transported back in time to when Lily and James were alive. There, they would get to know each other in a different way. Harry would finally be able to have a proper conversation with his parents. They could discuss the future, the prophecy, and how Harry has changed the wizarding world. Ginny could bond with Lily over their love for Harry and their Gryffindor spirit. It would be a very emotional and magical encounter.
One possible plot could be that Harry and Ginny are overjoyed at the news of Ginny's pregnancy. They start preparing for the baby's arrival by setting up a nursery in their home at Grimmauld Place. Ginny might take a break from Quidditch, and Harry would be extra protective, constantly worrying about her safety. Their friends like Hermione and Ron would be excited and offer their help, bringing baby clothes and giving advice based on what they've read in wizarding parenting books.
In such a fanfiction, perhaps it could explore an alternate universe where time and relationships are distorted. Maybe there's some sort of magic gone wrong that leads to this unexpected situation. It could also be about how they deal with the social and family implications of such a pregnancy.
