I am about 12 weeks pregnant. The smell, thought, and sight of food makes me vomitt. I know I am not eating enough and I am losing weight. I consume liquids, mainly milk all day. I've tried eating crackers, cold foods, soups, and eating at least once an hour, but nothing has helped. I do take a prenatal vitamin everyday. I'm nervous my eating habitts are very dangerous for my baby. What advice do you have?
