Well, Gamora's back story in Avengers Infinity War is quite tragic. She was from a race that Thanos decimated. He then took her in, not out of kindness but for his own purposes. She learned combat and survival skills from Thanos. However, she always had a moral compass that was different from her 'father'. This led to her being in a constant struggle within the story, especially when it came to the location of the Soul Stone, which Thanos needed. She tried to keep it from him at all costs.
Before the events of Avengers Infinity War, Gamora's life was shaped by Thanos. She was orphaned by Thanos' actions on her home planet. Thanos then took her under his wing, but it was more like a prison. She had to endure his brutal training methods. However, she used the skills she learned to plot against Thanos. She joined the Guardians of the Galaxy, which gave her a new family and a new purpose. Her past experiences made her determined to stop Thanos from getting all the Infinity Stones, as she knew the destruction it would bring.
In a fanfiction, Gamora's pregnancy could add an emotional layer to her relationship with Peter Quill. He could be overjoyed at the news, but also extremely fearful for her safety. Their interactions would be filled with a mix of hope for the future and dread of the impending war.
One possible fanfic could be where Spider - Man's death is more of a sacrifice to save others. Maybe he uses his powers to hold off Thanos' minions long enough for the remaining Avengers to escape. His last moments could be filled with thoughts of his friends and Aunt May, and his determination to do what's right.
The plot could revolve around Gamora's discovery of her pregnancy. She might initially be in shock but then decide to keep it a secret from most of the characters. She continues to fight alongside her comrades while trying to protect her unborn child. As the war progresses, she may start to show signs of pregnancy that are hard to hide, causing some of her allies to question her state.
They could have escaped Thanos' clutches earlier. If they had worked more closely together from the start, they might have noticed Thanos' trap sooner and found a way to avoid it. This would have changed the whole course of the Infinity War as Gamora wouldn't have been sacrificed and Peter would have had his full team intact.
