Well, I'm not into promoting such rather odd fanfic ideas. 'Harry and Sirius pregnant' goes against the original nature of the characters in the Harry Potter series. However, if you still want to look for it, try searching on some large - scale fanfic websites. But be aware that it may not be a very common or well - received genre within the fanfic world.
There may be such fanfiction in some niche corners of the internet, but this goes against the original nature of the Harry Potter series and is also a rather strange and inappropriate concept. J.K. Rowling's original works don't have any such plotlines, and most official and mainstream interpretations stay true to the original characters' relationships and story arcs.
The 'Harry and Sirius pregnant fanfic' concept is really far - fetched. Harry Potter's world is filled with magic, mystery, and deep emotional relationships that are based on friendship, family, and the fight against evil. This concept seems to take things in a direction that is not only against the original characterization but also challenges the moral and ethical boundaries of the story world. It's an example of how fanfiction can sometimes go to extreme and rather inappropriate lengths.
I'm not sure if there is such a specific fan fiction. Fan fiction can cover a vast range of wild and creative ideas, but this one seems rather unusual and might not be a common theme. However, the Harry Potter fan fiction community is huge, so it's possible that something like this exists in some corner of the internet.
Yes, there are likely some fanfics out there with that premise. The Harry Potter fandom is vast, and fans often come up with creative and alternative family relationships in their stories. You can try searching on popular fanfic websites like Archive of Our Own or Fanfiction.net.
It's also likely that they go to Romania. Given Sirius' knowledge of the wizarding world, he might know of a safe haven there. In Romania, they could be around dragons and learn about dragon - related magic. Harry would surely be fascinated by the dragons and it could be a place where he can grow stronger in a different kind of magical environment.
One major problem is that it goes against the nature of the relationship between Sirius and Harry in the original 'Harry Potter' series. Their relationship is more of a mentor - mentee or a father - son like bond, not a romantic or sexual one.
The relationship could also take a more complex turn. Other characters might get involved in their conflict. Some might side with Sirius, thinking Harry was in the wrong, while others might try to mediate. This outside influence could either help or hinder the mending of their relationship, depending on how it's handled in the fanfic.
Their relationship would be severely damaged. Harry would likely feel betrayed by Sirius. After all, Sirius is supposed to be one of his protectors. It would be a huge breach of trust. Sirius, on the other hand, would probably be filled with guilt if he realizes his mistake. He would have to work hard to regain Harry's trust, if that's even possible in the context of the fanfic.
Sirius helps Harry become more confident. By sharing his knowledge and experiences, Harry feels more capable. For example, when Sirius teaches Harry a difficult spell, Harry realizes he can master things he thought were out of his reach.
