You need to rest,dont over work yourself...i tried to do work and go out even when i was feeling this way and i almost fainted on the road,i had to rest for a long time in a shop before taking a cab home. The second time,i vomitted, and it wasnt in my first trimester o. You can imagine how terrible my first trimester was, so i will advice you to look for someone to help you when you cant do anything. Explain to your husband,he will understand.
