Well, I've seen a few. Some are really interesting in how they handle the concept. They might explore things like how the wizarding world would react to such a situation. However, not all of them are well - written. You need to dig through a bit to find the gems.
It's possible. Fanfiction platforms are filled with a vast array of stories. Since the Harry Potter fandom is so large, there may be writers who have decided to explore this rather unconventional idea. It might be a way for them to explore themes like identity, magic's unexpected consequences, or just to create a really unique and shocking story within the beloved wizarding world.
One possible fanfiction could be where they are excited yet nervous about the pregnancy. Ginny might be worried about how her Quidditch career will be affected while Harry is concerned about protecting his family from any potential dark threats. They could start preparing a nursery at Grimmauld Place with help from Hermione and Ron, painting the walls with magical murals.
Often, there's a theme of self - discovery for Harry. As he's in this unexpected situation, he has to reevaluate his life, his relationships, and his place in the wizarding world. There might also be themes related to the support or lack of support he gets from his friends.
The themes might include the disruption of the norm. Harry Potter is a hero figure, and this situation turns his life upside down. So it could explore how he copes with this sudden change in his identity. There could be a theme of secrecy as well, whether he wants to keep it hidden or not. And also the theme of acceptance, both from himself and from the people around him. The fanfiction might also touch on the implications for his relationships, like how it affects his relationship with Ginny or his other friends and family members in the wizarding world.
Another theme is the struggle between magic and normalcy. Pregnancy is a very normal human experience, but in the magical world of Harry Potter, it can be complicated by spells, potions, and magical creatures. So fanfictions often explore how the characters balance the two.
There could be many interesting plotlines in such fanfiction. Maybe it could explore how Tonks' pregnancy affects her role in the Order of the Phoenix. For example, she might have to step back from some dangerous missions, which could cause some internal conflicts within the group. Also, it could show how her relationship with Lupin develops during this time, like how they prepare for the arrival of their baby together, and how other characters like Harry react to the news of her pregnancy.
Another interesting one is 'Pregnancy in the Wizarding World'. This fanfiction doesn't focus on a particular main female character but rather on the general concept of pregnancy in the wizarding world. It includes different female characters from the series and how they might experience pregnancy with magic involved. It has some unique takes on the use of potions and spells to ease pregnancy discomforts.
In some fanfictions, Lily's pregnancy could be a turning point in the relationship between the Order of the Phoenix and some neutral wizards. The news of a new life on the way might inspire more people to side with the forces of good, seeing it as a symbol of hope in the face of Voldemort's growing power.
Yes, there might be some out there. Fanfiction often explores very creative and sometimes out - of - the - box ideas. However, this particular concept is quite a departure from the original Harry Potter story. Some fanfiction platforms may have such stories, but they might not be very common or in line with the traditional view of the Harry Potter universe.
