I just want to talk. Even though it's my third pregnancy, I feel like all I want is to sleep. And something kind of hurts. Like cramps. It feels like that. There's an appetite, but after one spoonful, I get disgusted. I think I like other people's food and it's unclear. The previous two pregnancies went well. I don't want to burden anyone in my family. What should I do?
