Hermione would probably be a great source of support for Harry. She would use her intelligence to research about any magical implications of such a pregnancy. Ron might be initially shocked but would eventually come around to support his friends. Overall, the characters would have to grow in different ways to adapt to this new situation.
Harry would likely become more protective and nurturing. His focus would shift from just his normal adventures to also thinking about the future of his child. Fred, on the other hand, might become more serious and responsible.
For Harry, he would experience a whole new range of emotions like fear, excitement, and love all at once. This would make him more empathetic towards others going through difficult situations. Fred would have to face his own insecurities about being a father. He might start to think more about stability and providing for his family, which is a big change from his usually carefree nature.
Well, Hermione's usually logical and rational, but the pregnancy can make her more emotional at times. This is a new side of her that the fanfiction can explore. Fred, on the other hand, may find himself having to grow up quickly. He has to think about providing for his family now, which is a big change from his carefree days at Hogwarts.
The characters would develop in many ways. Harry could become more cautious as he has someone else to think about now. He may also struggle with the new identity of being a pregnant person in a world that doesn't expect it from him. Tom might find himself in a position where he has to make sacrifices for the first time, which could change his whole view of power and control.
Their relationship would likely become more serious and responsible. They'd have to put aside some of their youthful antics as they now have a child to think about, even if it's from the future. There would be a new level of trust and understanding as they work together to deal with the situation.
One possible plotline could be the initial shock and disbelief from Harry and those around him. His friends might be very surprised and have to deal with this unexpected situation. Another could be how Harry and Fred navigate their relationship now, whether they decide to raise the child together or face many challenges in doing so.
Harry would likely become more responsible and protective. He'd have to grow up quickly to face the situation. Lily, on the other hand, might become more assertive in her decisions regarding the pregnancy and their future.
During the pregnancy, they would have to learn to communicate even better. There could be times when Hermione is hormonal and Fred doesn't understand her mood swings at first. But as they grow through this experience, they would learn to read each other's emotions more accurately. Fred might also start taking on more responsibilities around the house, like making sure Hermione has a comfortable place to rest, while Hermione could be sharing her knowledge about the upcoming baby's development with Fred.
It would deepen on an emotional level. They would have to communicate more about their future and the responsibilities of raising a child. Hermione might rely on Harry more for emotional support during her pregnancy, and Harry would grow to be more nurturing towards Hermione.
It's possible that there could be some strain on their relationships. The stress of being in a different time and the fear of changing things could cause arguments. Maybe they have different ideas about what they should do while in the past. For instance, Fred and George might want to have some fun and explore, while Harry is more focused on achieving a specific goal related to the future, which could lead to some friction between them.
Harry would likely become more responsible and mature. The news of Fleur being pregnant would force him out of his comfort zone and make him think about the future in a more serious way. Fleur would also change, she might become more protective and nurturing. Her Veela side might also come out more in terms of being possessive of Harry and the unborn child.
For Harry, his focus would shift from just fighting Voldemort or dealing with school stuff. He would be more concerned about providing for Daphne and the baby. Daphne, who might have been a bit more reserved before, could become more outspoken as she has to fight for her relationship and the future of her child. They both would change their social circles too. Maybe they would be closer to those who support them and distance themselves from those who oppose their relationship.
