Maybe in the fanfiction, there's a magical spell that makes them see their true feelings. Cana has always had a bit of a crush on Natsu, but Natsu has been oblivious.

In the 'natsu gets cana pregnant fanfiction', perhaps it starts with a magical accident. Natsu and Cana might be exposed to some strange magic that causes an unforeseen bond between them.

Maybe they are in a dangerous situation and Natsu saves Wendy. In the heat of the moment, they share a kiss out of relief and a new - found closeness.
Some of the younger guild members like Wendy would be a bit shy about it. They might blush and look away when they see Natsu and Cana together after the kiss.

Their married life could be full of adventure. Natsu, with his fiery spirit, might bring excitement and spontaneity.

At home, they would probably have a cozy place filled with mementos from their adventures, and they'd often have friends over for parties and celebrations.
Maybe an old enemy of Natsu's resurfaces. This enemy is jealous of Natsu's newfound happiness with Cana and tries to take Cana hostage to force Natsu to fight him. This would create a major conflict in the fanfiction.

They could face challenges like dealing with the guild's reactions, some of which might be positive and some negative. And they have to prepare for the arrival of the baby together, which includes finding a proper place to live and getting the necessary supplies.
