Odd Sickness

Angela-Marie
I don't know how to explain it but for the last week I've just been feeling off. I'm 7 weeks 5 days and if I'm not sitting or laying down I feel sick. Not necessarily like I'm going to vomit but like if I stay standing too long or moving a lot it will get there. I haven't been able to stand the smell of our kitchen or cooking food. I can eat fine as long as I don't smell the food cooking. 
My husband thinks I'm being lazy and just don't want to clean or do dishes. He goes to classes from 7-3 and then works from 4-10 every day so it's hard for him to help and I hate asking. We have a pile up of dishes about a week old (it doesn't smell trust me I'd know) but it is messy and I hate it. I'm also constantly exhausted. 
Any tips on how to deal with this? Anyone else not sick but just kind of off?
