The Crown Princess Is Naturally Pregnant

I was born pregnant, but my whole family regarded me as a freak because of my plump figure. My twin sister bullied me like a beast because of my slender figure, and my biological parents even treated me like a slave. Later, my sister and I entered the palace to marry two princes at the same time. The prince my sister married was not congenitally qualified and could not conceive her. But the second prince I married became more and more handsome. After three years of having two children, the father ascended the throne and proclaimed himself emperor based on the son's superiority. My sister was jealous and burned me alive on the day I was crowned queen. When I opened my eyes again, I went back to the day before entering the palace. This time, my sister wanted to marry the second prince first and wanted to marry her to the world. I laughed. The second prince has a truly incompetent constitution. Not only will his sister not be able to have any more children after she marries him, but she will also be treated as a plaything of eunuchs...
