I haven't come across a 'Loud House Luna pregnant' fanfic myself. However, the world of fanfiction is vast. It's possible that some fans with a very creative or different vision of the 'Loud House' universe have written something like this. You can check various fanfic platforms. But also be aware that some platforms have rules about the type of content they allow, and this kind of plot might not be in line with the family - friendly image of the original show.
I'm not sure if there is a specific 'Loud House Luna pregnant' fanfic available. Fanfics can cover a wide range of topics and interpretations within the 'Loud House' fandom, but this particular theme might be quite rare or not conform to the general family - friendly nature of the show. You could try searching on fanfic - specific websites like Archive of Our Own or FanFiction.net, but keep in mind that not all content on these sites may be appropriate or in line with the show's intended audience.
There might be such a fanfic out there, but it's not something that is commonly talked about. The 'Loud House' is mainly a family - oriented show, and a plot like Luna being pregnant would be a very different take. If it exists, it would likely be part of a more niche or alternate - universe type of fanfic. You could search for it in the more extensive fanfic communities, but don't be surprised if it's difficult to find.
