Another idea is that it could be a deep exploration of their relationship. The pregnancy could be a metaphor for a new level of closeness and cooperation between them. It could start with an accidental situation that forces them to re - evaluate their feelings for each other. As the 'pregnancy' progresses, they learn more about themselves and each other, leading to a transformation in their relationship.
There are several great ones. For example, 'The Diplomatic Bond' which focuses on their political interactions and how they gradually build a deeper understanding outside of the usual rivalries. It shows their growth as nations in a non - romantic but still engaging way.
I'm not sure of specific fanfics with this exact combination, but you can try searching on popular fanfic platforms like Archive of Our Own. There are often many Hetalia - related fanfics there. Just use the search terms 'Hetalia', 'Russia', 'female America' and 'pregnant' to narrow down your search.
Most fanfiction platforms have strict rules against 'lemon' or adult - themed content. So, instead of specifically lemon fanfiction, I'd suggest exploring fanfiction where the relationship between Russia and China in the Hetalia universe is depicted in a positive and interesting light. Maybe something that delves into their historical connections or how they might cooperate in fictional scenarios.
A third common theme is the personal relationship between the characters. Beyond the political and geopolitical aspects, fanfictions often delve into how Russia and America as characters interact on a personal level. This could involve feelings of mistrust, but also unexpected friendships or alliances. Some stories might explore how their cultural differences play into their relationship, with Russia's more reserved nature compared to America's more outgoing and brash attitude creating interesting dynamics.
I'm not entirely sure which specific 'russia x america lemon fanfic' you are referring to. However, generally in fanfics like this, it might explore a fictional relationship between Russia and America in an often creative and non - traditional way. It could involve elements of friendship, rivalry, or some sort of cultural exchange written from a fan's perspective.
America's brash and confident personality would likely lead to him initially being in denial or trying to handle the situation on his own terms. He might see it as a challenge to overcome, like he does with many things in the Hetalia series. For example, he could try to come up with some grand, unorthodox solution without really thinking it through.

You can also check out fanfiction communities where fans discuss and recommend their favorite works.
