Concerned & Feeling lousy

I am almost 8 weeks and for the past 2 weeks have felt critically exhausted even though I've been going to bed by 9 every night. And I've been experiencing nausea 24/7. I wear the sea bands it helps for a Lil while, while I can stand wearing them. I have no energy. As soon as I get home from work I walk the dogs, cook dinner for the fam, try to eat, then lay in bed hoping I can either keep it down or get sleep. I didn't feel this terrible with my 1st. And my husband told me he had a dream that I got obese. I'm starting to wonder if it's just pregnancy related illness or mild depression.
