Was Saga pregnant in The Bridge?

Could you please clarify for me, was the character Saga indeed pregnant during the events depicted in the television series or film titled "The Bridge"? This question arises from the intricate plotlines and character developments that often occur in such narratives, and I'm curious to know if Saga's pregnancy played a significant role in the story or if it was merely a subtle detail among many. Additionally, did this pregnancy status add depth to her character or serve as a catalyst for certain plot twists?
