Well, AO3 is probably your best bet. It's known for its large collection of fan - created works and its acceptance of different and unique concepts. But don't limit yourself to just one site. Check out Tumblr as well. Sometimes bloggers on Tumblr share links to interesting fanfictions, and you might be able to find what you're looking for through their recommendations.
You can try Archive of Our Own (AO3). It has a huge database of fanfictions and a good search function. Just type in 'female sherlock pregnant' and see what comes up.
Fanfiction.net could also be a place to look. However, the tagging system there might not be as precise as AO3. But still, it's worth a try. Another option is Wattpad, although it has a broader range of content and you might need to do more sifting through the results.
