I'm not sure if there is a specific fanfiction exactly like that. There are a vast number of fanfictions in the Naruto fandom, and while some might explore relationships between different characters, it's difficult to say for certain without searching through various fanfiction platforms. It's also important to note that such a concept might be quite out - of - character for the original Naruto story setting as Hidan and Sakura are from very different story arcs and character groups.
There could be, but it might not be a very common or canon - compliant one. Fanfictions often take creative liberties and pair characters in unexpected ways. However, this particular pairing of Hidan and Sakura resulting in pregnancy is rather unusual given their personalities and the overall Naruto narrative. You would probably have to dig deep into some of the more niche fanfiction communities or websites to find something like that, if it exists at all.
