The same thing happened to me. Then I went to the beach for a week & we went to a nice restaurant every night & I couldn't even eat but 2 bites of my food. I would watch my family eat & be so mad & jealous that I couldn't eat & was miserable. I didn't even gain any weight until about 20 weeks pregnant. I lost about 8 pounds before that. My Dr wasn't concerned since the baby was measuring right. It will go away eventually...but if you're like me, you still have a while. Even once mine came back I could only still eat what's a normal meal which is usually a normal meal for a kid. Just within the last week I've been actually eating like a pregnant person. & I'm 24 weeks now
