A big challenge would be security. There could be enemies who see the unborn child as a threat or a valuable asset to capture. Sansa and the Dornish character would have to constantly worry about protecting themselves and the baby. Moreover, they would need to figure out how to combine their different political standings. Sansa has her own influence in the North, and the Dornish character has his or her place in Dorne. Deciding how to manage this for the future of their child would be a major task.
One challenge could be Sansa's mental state. After all the trauma she's been through with Ramsay, being pregnant by him could lead to extreme psychological distress. Another challenge could be the reaction of the people around them. The Northmen, for example, would likely be horrified at the thought of Sansa having Ramsay's child. And Ramsay himself might see the child as another tool for his sadistic games, creating a dangerous situation for Sansa and the unborn baby.
Sansa would likely become more determined and resourceful. The pregnancy would force her to think not just about her own survival but also about the life growing inside her. She'd have to be stronger to face Ramsay's madness.
If Sansa was pregnant in this fanfiction, it could potentially be a catalyst for a new alliance. Jaime, despite his past actions, has certain skills and influence. This could be used to protect Sansa and the unborn child. However, they would face many enemies. The Lannisters might not accept Sansa easily, and the Northmen may be skeptical of Jaime's intentions. Sansa, on the other hand, would have to use her wits to navigate through this difficult situation, perhaps trying to use the pregnancy to her advantage in the power games of Westeros.
Sansa could grow in terms of her resilience. The pregnancy in such a terrible situation with Ramsay would force her to become stronger. She would have to find ways to protect not only herself but also the unborn child, which could lead to a more hardened and strategic Sansa.

In these fanfictions, the pregnancy can be a symbol of hope or a source of conflict. For example, in some stories, their union and the pregnancy might face opposition from certain factions due to political reasons. The writers usually try to stay true to the original characters' personalities while adding their own creative twists.
Sansa often becomes more politically savvy in fanfiction involving the Hound. She may use her experiences with him and her time in various courts to her advantage. This development could lead to her having more power and influence, and her relationship with the Hound might be affected as she becomes more of an equal to him in terms of strength and intelligence.
Societal and family pressures could be another big challenge. Their families might have different expectations about how they should raise the child. And in the public eye, there could be a lot of speculation and judgment, which can be difficult to handle during such a personal and vulnerable time like pregnancy.
Well, first off, the characters are from completely different universes. Naruto has ninja powers and a very different cultural and story background compared to Sansa's medieval - like, political world in Game of Thrones. This makes it hard to create a believable and coherent story.
