In the fanfiction, they could see a future where Voldemort somehow returns or his followers create a new dark force. Harry and Ginny then use their knowledge of the future to find and destroy the source of this new threat before it becomes too powerful. They might go on a dangerous adventure, traveling to different magical places to gather information and allies.
One possible plot could be that they see a future where the wizarding world is in great danger again. So they start to train young wizards secretly to prepare for the upcoming threat.
Well, one possibility could be that the kids from the future come back to prevent a great disaster in the present. Maybe a dark wizard that was defeated in their time has somehow found a way to be reborn in the past (the present in the story), and they need to stop it before it's too late.
One possible plot could be that the child from the future comes back to prevent a great disaster. Maybe a dark wizard in their future time has found a way to rewrite history and the child has to make sure Harry and Ginny meet and fall in love at the right time. The child might also have some special powers inherited from their parents which they use to face various challenges in the past.
One possible plot could be that Harry is under the influence of a dark spell or some mind - controlling magic that makes him kidnap Ginny. Maybe he's been hexed by a powerful dark wizard who wants to use Ginny as a bargaining chip against the Order of Phoenix. So, Harry, without his true self in control, takes Ginny to a hidden location.
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.
It could be a new dark wizard that they see in the future. Maybe someone who was overlooked during the fight against Voldemort but has been secretly gathering power.
Well, perhaps they will discover that magic has merged with Muggle technology in the future. Harry and Ginny could be amazed to find flying cars that are powered by both magic and electricity. They may also encounter new forms of dark magic that they have to fight against, or they might see a future where the wizarding world has achieved complete peace and harmony, and they play an important part in maintaining that peace.
It could be that Ginny uses a dark magic spell in a moment of anger or recklessness. Harry, being the defender of the light, punishes her by making her study the history of the harm caused by dark magic. As she delves into this study, she realizes the error of her ways and has to work hard to regain Harry's trust. This could involve her doing community service within the wizarding community related to those who have been affected by dark magic.
One possible plot could be that Harry and Ginny go to a secluded wizarding cottage by the sea. They spend their days exploring the nearby magical creatures and hidden coves. At night, they sit by the fireplace and share stories from their Hogwarts days, strengthening their bond even more.
One possible reason could be a growing apart due to their different career paths. Harry, being deeply involved in the wizarding world's security and Ginny having her own Quidditch career. Another reason might be the stress of living in the public eye. Their relationship may not be able to withstand the constant scrutiny and pressure from the wizarding community.
In this fanfiction, Ginny might find strength within herself that she didn't know she had. She could start to form new relationships with other characters who help her through the pregnancy. For example, she could become closer to Hermione, who could offer practical and emotional support. The pregnancy could also be a catalyst for changes in the wizarding society's view on single motherhood. It could lead to new laws or social norms being established, and Ginny could be at the forefront of this change.
