Sickness

I know this may sound really weird but since I've gotten pregnant I CANNOT cook in the kitchen. It just makes me throw up the whole time. If I see how it's being made I can't eat it. My husband cooked dinner but the smell has me gagin already. :( but see when he brings food home from places I don't get sick. Do you guys think it's the smells and just knowing how it's being fixed. I've never ever been like this. I just never can eat what I cook.
