Yes, in the vast world of fanfiction, there are some really out - there concepts. There could very well be such a fanfiction exploring this highly unusual and creative scenario. However, it would likely be a very niche and perhaps controversial piece due to the nature of the concept. It might involve a lot of creative license in terms of how the pregnancy could even be possible in the Naruto universe's lore and mechanics.
I'm not sure specifically if there is one. Fanfiction is so diverse that it's hard to keep track of every single concept. But given the creativity of fans, it wouldn't be too surprising if someone had written a story like that. Naruto and Kyuubi have a very unique relationship in the original series, and this would be a very extreme way of exploring that relationship in a fan - created story.
There might be. Fanfiction often takes existing characters and relationships and twists them in unexpected ways. Naruto and Kyuubi are two very well - known elements from the Naruto series. Some fanfiction writers like to come up with really wild ideas to explore different aspects of the characters. This 'pregnancy' idea is definitely on the far end of the spectrum of creativity, but it's possible that a writer has delved into this concept in a fanfic.
