Apart from the logical explanation — it isn't a given that a woman will get pregnant even if she's sexually active — the reason Sansa didn't get pregnant by Ramsay is that the show made a serious deviation with Sansa's plot.
Fortunately, the answer is... nope! Sansa is not pregnant with Ramsay's baby, at least according to a reliable Game of Thrones spoiler and news website Watchers On The Wall.
Following the Battle of King's Landing and the subsequent assassination of Daenerys, she declares the North an independent kingdom and is crowned Queen in the North. Soon after, Sansa gave birth to the twins Lyonel and Cassana.
One of the less pleasant theories to crop up during this years series of Game of Thrones (and that's saying something) was the idea that Sophie Turner's Sansa Stark, newly liberated from her abusive husband Ramsay (Iwan Rheon), would end up pregnant with his child regardless.
This tension reached a cultural nadir in the middle of the show's fifth season, with the episode “Unbowed, Unbent, Unbroken.” In that hour's conclusion, Sansa Stark is married to the psychopathic Ramsay Bolton, who proceeds to conjugate their new union by raping and assaulting her, and forcing Sansa's surrogate brother ...
Tyrion is initially opposed to the marriage, but is eventually enticed by the prospect of becoming Lord of Winterfell, and so agrees to marry her. Sansa is shocked one morning to learn that she is being fitted for a gown to marry Tyrion that day.
And her story closes in a way that proves it. In the Game of Thrones finale, Sansa becomes Queen of the North. After Tyrion Lannister convinces representatives of the Seven Kingdoms that her brother Bran deserves to be king because he has the least ego, Sansa steps forward to demand that the North remain independent.
Who's the father of Cersei's child? The father, based on the all the evidence and context, is again Jaime Lannister, Cersei's brother. The first time we heard about the pregnancy was back in season 7, when Jaime was still knocking around King's Landing.
In the books, the Hound also had a more overt attraction to Sansa. When he asks her to leave with him and she refuses, he kisses her—and at knifepoint, demands a song for her.
Before the writers finally realized Sansa Stark was more than just a wife, she spent the first few seasons of Game Of Thrones being tossed from man to man. First, she was betrothed to Joffrey, then married to Tyrion Lannister, and then married to the horrible Ramsay Bolton.
Sansa develops a crush on the well-liked and handsome knight Loras Tyrell in Season 3. Olenna and Margaery plot to marry Sansa to Loras and extend their power over the North.
The Hound falls in love with Joffrey's betrothed, Arya's sister Sansa, enchanted by her innocence and romantic dreams. When he decides to abdicate his position during the Battle of the Blackwater, she's the last one he visits.
Sophie Turner has credited her marriage to Joe Jonas as something that kept her spirits high after the end of Game of Thrones. The actor played Sansa Stark in the HBO series, which ran for eight seasons from 2011 to 2019.
“Battle of the Bastards,” the ninth episode of Game of Thrones' sixth season, saw the long-awaited showdown between Jon Snow and Ramsay Bolton finally take place, culminating in Ramsay's death at the hands of Sansa Stark.
Even so, Ramsay marries Fake Arya in the godswood. A bard by the name of Abel arrives uninvited, with six women followers, to perform for the wedding. Theon believes that he hears his name ("Theon") whispered by the godswood, after months of thinking of himself only as Reek.
As Sansa points out during Bran's election as king, he isn't able to have children due to being paralyzed below the waist.
In the show, Arya is believed to be 18 years old in Season 8 while Gendry is believed to be around 23 (though his age isn't confirmed onscreen). In real life, actors Maisie Williams and Joe Dempsie are 22 and 31 respectively.
Many fans see The Hound as even more than a friend to Arya. Having put his life on the line several times for her and always looking out for her, some think he becomes something of a father figure to her.
The Mountain, before he was a giant undead murderer, basically shoved The Hound's face into a fire and burned him terribly over basically nothing (The Hound was playing with one of The Mountain's toys when they were both boys).
While she was initially happy about marrying Robert, he didn't return Cersei's affections and repeatedly cheated on her. She then resumed her incestuous affair with Jaime, resulting in the births of Joffrey, Myrcella, and Tommen.
Even still, her ambition has been indirectly responsible for the deaths of all three of her children with Jaime: Joffrey (killed by poison, courtesy of House Tyrell); Myrcella (also poison, out of revenge for Oberyn Martell, whom Cersei had killed to get to Tyrion); and Tommen (suicide, after Cersei orchestrated a mass ...
So no, they have definitely not slept together. Sansa doesn't want him and Petyr's desire for power outweighs his desire for Sansa.
Some of the beloved characters in Game Of Thrones received an unlikely happy ending, including Sansa Stark becoming Queen in the North and Tyrion Lannister retaining his position as Hand. However, not all of the characters were as lucky. Here are five characters in GoT who had happy endings and five who didn't.
