Hello girls, tomorrow is 8 weeks and literally last week I started feeling not so good, feels nauseous, gets dizzy, but doesn't vomit, head spins, constantly wants to sleep, can't stand for long. Very little eats, almost nothing comes out, feels hungry, but doesn't want to eat. Has anyone had this? Is it normal or do you need vitamins?
