Hi. I'm 6 weeks pregnant today and and been feeling very sick for the last week. I haven't been vomiting, but I'm having headaches, feeling very nauseous and struggling with my appetite all day and during the night and as a result getting little sleep. I feel pretty useless as I'm doing nothing around the house and feeling to ill to cook. I know everyone is different, but is it normal to feel this ill at 6 weeks and how long did it last for other people?
