Yes, there are quite a few. You can find them on some fanfiction platforms. Some might focus on their unique friendship and the adventures they could have together in the Sonic universe.
You can try looking on Fanfiction.net. It has a large collection of Sonic - related fanfictions, and there's a good chance you'll find some tails x cream ones there.
A frequent theme is adventure. They go on various adventures together in many fanfictions, which strengthens their bond. Also, the theme of innocence is there. Since both characters are relatively innocent, their relationship is portrayed in a very pure and sweet way. For example, in some fanfictions, their first kiss is a very shy and hesitant moment.
Their relationship would likely become more mature. They would have to rely on each other more than ever. Tails would become more protective, and Cream would be more nurturing. They would share responsibilities like taking care of the baby, which would bring them closer together as they work towards a common goal.
I'm not sure specifically what the 'tails x cream love story' is as it could be a very unique or fan - created concept. It might be a story about two characters named Tails and Cream having a romantic relationship, perhaps in the context of a particular game or fan fiction world where they go on adventures together and their love blossoms over time.
Another storyline could be set in a world where all the Sonic characters' abilities are switched. Tails has Cream's flight ability, and Cream has Tails' mechanical genius. They have to figure out how to use their new abilities to stop an evil plot by Dr. Eggman. It would be full of humorous moments as they struggle to adapt and work together in this new situation.
There's a fanfiction where Tails and Cream team up with other Sonic characters for a Christmas party. They each contribute something special.

I haven't actually read such fanfiction, but generally in fanfiction, the 'pregnant' aspect might add an element of family - building or new relationships developing.
