No, Kate Austen was not pregnant on the television series Lost.
While Kate Austen became a primary caregiver for a baby on Lost, this child, Aaron, was not biologically hers. Aaron was the son of Claire Littleton, another survivor of Oceanic Flight 815.
The True Nature of Pregnancy and Deception on the Island
Although Claire Littleton was visibly pregnant and later genuinely gave birth to her son Aaron on the island, the narrative surrounding pregnancy on Lost involved intricate layers of deception, particularly concerning how a baby came to be associated with Kate.
Specifically, it was part of the storyline that Claire faked elements related to giving birth to a baby that was ultimately presented as Kate's. Jin-Soo Kwon played a significant role in facilitating this intricate deception. This meant that while a character was indeed pregnant, the overall presentation and true parentage of the child in relation to Kate involved deliberate misdirection within the plot.
