Hello! Can you please tell me if it's possible to lose weight during pregnancy, at least on my face? I'm so tired and it really bugs me. My mother-in-law constantly says that I have a big baby. Although he weighs accordingly to the term. She says that the belly is big and constantly looks at me and observes what I eat ??‍♀️?. Who doesn't mind saying that the belly grows quickly, I don't even imagine what kind of belly there should be during pregnancy if not like this.
