Junk food in pregnancy

I cannot stomach anything except for fast food. I'm 17 weeks pregnant amd feel guilty about it. I used to love cooking but now I hate being in the kitchen. I only go out and crave burgers, fries, pizza, nuggets, garlic bread from fast food joints and restaurants. Sometimes pasta from Noodles and Company or an Italian restaurant. Anybody had this issue? Did it hurt your baby in any way? My family screams at me saying I'm being a horrible mom and that I should eat veggies and greens because the way I eat us hurting my baby. I had a salad once and almost vomited.

On a side note my blood works is all good. I'm not gaining much weight and I feel satisfied after eating some "junk food."

I gained 2 pounds since I got pregnant.
