Husband is making me feel bad.

I am pregnant and people that have been pregnant before know how our sense of smell is in overdrive. I asked my husband if he wouldn't mind doing dishes and taking out trash because I can't even go near them without gagging and almost throwing up, he agreed that he would do them no problem. Mind you I still do all the other house work including repairs to the house and make him dinner every night, rub his back when it hurts pretty much caitor to his every need. He has an easy job. Before he goes to work and on his days off he just sits  on his chair and watches T.V while I am cleaning, making dinner and fixing something that is falling apart in our house. I don't know why he gets so angry when I ask him to do two things until my hormones level out. Am I asking two much from him? It's really making me feel like a bad wife when I ask him and I told him if I could do it I would but right now the smells are making me sick :(
