One common theme is the anticipation and excitement of becoming parents. Harry and Luna might be shown preparing for the baby, like setting up a nursery in a magical way.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Just search for 'Harry and Luna pregnant' and you'll find a variety of stories with different plotlines and writing styles.
There might be some fanfictions exploring this concept in a more innocent or creative way. However, most of the time, such a plot can be quite out - of - character for the original Harry Potter universe. It's important to look for fanfictions that are rated as appropriate and that respect the essence of the characters.
It could be a story where Luna has a premonition about having a child with Harry. They initially don't believe it but as time passes, some strange magical signs start to occur that seem to confirm it. So they start preparing for the baby in a very sweet and naive way. They might ask for advice from Hagrid on how to take care of magical creatures (thinking the baby will be like a magical creature in some ways) and from Hermione on how to study up on child - rearing in the wizarding world.
I'm not sure of a specific fanfiction on this. However, you could try searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Look for tags related to 'Luna Lovegood' and 'pregnancy' within the Harry Potter section. There are often many creative and well - written fanfictions out there that might fit what you're looking for.
A different plot could be centered around Luna's pregnancy in the context of her family. Maybe her pregnancy re - awakens some long - forgotten family magic. Her family has always been a bit of an enigma in the wizarding world. Her pregnancy could trigger some magical events that draw the attention of the Ministry of Magic. The Ministry might be suspicious or interested in how this could affect the balance of magic in the wizarding world. Meanwhile, Luna is just trying to have a normal pregnancy and raise her child in a world that is both curious and sometimes a bit hostile towards her family's unique magic.
You can try searching on popular fanfiction websites such as Archive of Our Own (AO3). There are often dedicated sections for different fandoms, and you might be able to find Noctis and Luna - related fanfictions there. Another option could be Fanfiction.net, though the tagging system might vary.
Often, there are themes related to the future of the baby. What kind of world will the baby be born into? Will it have special powers or a special destiny? And sometimes, there are themes of protection. Luna and those around her might be very protective of the unborn child from various threats in the story's universe.
For Harry, his growth could be shown through how he becomes more open - minded. He starts to embrace Luna's quirks and her different way of seeing things, which in turn makes him more accepting in general. For example, he might initially be a bit hesitant about Luna's belief in some of the more out - there magical creatures, but as they date, he starts to see the beauty in her imagination.
In a lot of fanfiction, they are indeed considered soul mates. Harry has been through so much trauma and Luna, with her off - beat charm and deep understanding, can reach parts of Harry that others might not. For example, she can see thestrals because she has also witnessed death, which gives them a special connection that some writers like to explore as a soul - mate - like bond.
