Well, perhaps there's a plotline where the wizarding community discovers the pregnancy and there's a big scandal. This could lead to Hermione and Draco facing a lot of judgment and having to fight against the prejudice. Or it could be that the pregnancy is part of some sort of magical prophecy or curse, which adds a whole other layer of mystery and adventure as they try to figure out what it all means and how to deal with it.
One possible plotline could be a story where Draco realizes his true feelings for Hermione later in life. He might initially approach her with the idea in a rather clumsy way, leading to a lot of misunderstandings and drama. For example, he could be from a family that is pressuring him to have an heir, and he sees Hermione as the perfect person to have a family with. But Hermione is focused on her career and has to decide if she wants to put that on hold for a relationship and potential pregnancy.
One possible plotline could be that they initially try to hide the pregnancy from everyone due to the social implications in the wizarding world. Draco might be conflicted between his family's expectations and his new - found feelings for Hermione. Hermione, on the other hand, is dealing with her own fears and the practical aspects of being pregnant while still in school or involved in the fight against dark magic.
One plotline could be that they are magically bound to the apartment and can't leave until they resolve some deep - seated issues between them. Maybe there's a spell that requires them to get along and understand each other's perspectives.
The other Gryffindors would likely be divided. Some would be outraged, thinking that Hermione has betrayed the house by getting involved with a Slytherin, especially Draco Malfoy. However, others might be more understanding and see that love can cross house boundaries. In Slytherin, Draco's friends would also have mixed reactions. Some would be proud that Draco has managed to get Hermione pregnant, seeing it as a sort of conquest, while others might worry about the implications for their standing in the wizarding world.
One possible plotline could be that Draco kidnaps Hermione due to some dark family obligation related to her birth. Maybe there's a prophecy that involves her and his family wants to control the situation. Another could be that he's misinformed about her birth and thinks she's a threat to the wizarding world as he knew it. So, he takes her to figure out the truth.
One possible plotline could be that Draco realizes the error of his ways immediately after cheating. He spends a great deal of time groveling and trying to prove his love for Hermione anew. He might do grand gestures like giving her rare magical items or standing up to his old pure - blood supremacist friends when they say mean things about Hermione. Hermione, initially hurt and angry, gradually sees his sincerity and decides to forgive him as she still has deep feelings for him.
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.

One possible plotline could be that they accidentally end up in a situation where Hermione gets pregnant, and then they have to deal with the reactions of their friends and family. Maybe they initially keep it a secret and struggle with how to break the news.
Well, in some fanfics, the plot might revolve around Hermione's pregnancy being a result of some magical accident or a prophecy. This could lead to them having to figure out how to deal with the implications. Some stories may focus on how their relationship changes. Draco might become more protective of Hermione and start to see the wizarding world from her perspective. It could also involve them having to hide the pregnancy from certain people in the beginning, like the Malfoy family who might not approve.
Maybe they meet in a secret place during their school years, away from the prying eyes of their classmates.
