I think it’s a begonia.. right?

I’m not sure what colors the leaves are supposed to look like, it was losing leaves so I repotted into a bigger pot with organic soil then it grew 10 inches, spouted like 20 new leaves and a new stalk lol. But it’s like red on the underbellies of the leaves and green with white spots on top. It gets zero direct sunlight, all indirect sunlight and is indoors. I’m almost sure it’s some kind of begonia, and I think it has a plant cold with the yellowness on the edges 🤣 I’m also propagating my jade plant so that’s the little plant in the third pic, it’ll be in its own pot next week.
