Is it normal to feel tired n having food cravings. Im nauseous but haven't thrown up. I feel really tired n it feels lik3 I have some weight gain around my stomach(but I'm a Lil chubby). I barely wanna get up n do anything. I have all the symtoms of a prego person, tired, backache, body aches, food cravings, n heightened sense of smell. my boobs don't really hurt as much as they did a couple days ago.
