Food aversions

I'm 7 weeks with my first child. I used to love veggies and healthy foods. Now the thought of these foods alone make me so sick. 
I'm noticing that one day I'll want something and think okay this is going to help the rest of this first trimester. Then the next day I'm like get that away from me. We are spending so much money on food. I can't grocery shop bc one second I'll want something the next it makes me sick. 
I also notice that when I want something I need to have it like right that second. My husband is getting so mad at me. Is this happening to anyone else?
