In such a fanfic, Daenerys being pregnant adds an extra layer of complexity to the revenge plot. She might initially be hesitant to act because of her unborn child, but Kinvara's actions could be so heinous that she has no choice. She could use her dragons (if they are part of the story) to intimidate Kinvara or those associated with her. She might also use her political acumen to isolate Kinvara from any support system, slowly but surely exacting her revenge while also ensuring the safety of her pregnancy.
There might be such a fanfic out there, but it could be quite difficult to find. It depends on how niche the combination of these elements is in the fanfic community. Maybe reaching out to dedicated fan groups or forums related to the source material (assuming it's from a particular series) could help in the search.
I'm not sure specifically as it could be a very niche or fan - created story. It might be a fanfiction where Daenerys is pregnant and Kinvara is involved in some way in the plot, perhaps as a supporter, an antagonist, or having some other relationship to the pregnant Daenerys. But without reading the actual fanfic, it's hard to say for sure.
You might try searching on popular fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. These platforms often have a large collection of fan - created stories, and you may be able to find the 'daenerys pregnant kinvara fanfic' there if it exists.
The fanfic might center around Daenerys's pregnancy in 8x06 as a symbol of hope. Despite all the chaos and destruction that has been going on, her unborn child could represent a new beginning. It could show her preparing for motherhood, thinking about how she wants to raise her child in a world she has fought so hard to change.
Well, perhaps in the fanfic, Aegon is initially seen as the rightful heir, but then Jon and Daenerys fall in love. Daenerys gets pregnant, and this throws the political landscape into chaos. Jon may have to fight for his place beside Daenerys and the unborn child, while Aegon might see the baby as a threat to his claim. There could be a lot of emotional turmoil, with Daenerys caught in the middle, trying to decide what's best for her child and the future of the Seven Kingdoms.
One possible plot could be that Daenerys' pregnancy is a cause for political unrest. Varys, being poisoned, might have some knowledge about who is behind it. Maybe he was poisoned by someone who wants to use Daenerys' unborn child as a pawn in the power struggle. His death could then set off a chain of events where Daenerys has to fight even harder to protect her child and her claim to the throne, all while trying to figure out who killed Varys.
Well, it could start with Jon and Daenerys arriving in Pentos. Maybe they are in hiding or on a diplomatic mission. Then Daenerys discovers she is pregnant. This could lead to a whole series of events. They might have to deal with local politics in Pentos as they try to protect their unborn child. Jon could be worried about the safety of his family in a foreign land, and they might face threats from various factions who either want to use the baby for their own gain or are against their union.
In this fanfic, the plot could center around the relationship between Daenerys and Ghost during her pregnancy. Does Ghost have a more sentient role? Maybe he protects her in a more involved way than normal. Daenerys could also struggle with how to introduce this unique situation to her followers. Will they accept her and the unborn child? This could lead to a lot of internal and external drama for her.
It could be about the challenges they face. Maybe Daenerys discovers she's pregnant during a difficult time, like a war or political unrest. Jon is by her side, but they both have teary eyes because of the uncertainty of the future. Their unborn child becomes a symbol of hope in a dark world.
One possible plot could be that Varys poisons someone who he believes is a threat to Daenerys's unborn child. He might be acting out of loyalty to Daenerys and her future reign. Maybe he poisons a political rival who has been spreading rumors about the paternity of the child or planning some sort of harm to Daenerys during her pregnancy.
