Kinda worried

So I'm 9 weeks as of tomorrow. I'm worried, I'm not showing at all and have lost 2 pounds. When I found out I was pregnant at 6 weeks I was 110 and now I'm 107.5 . I'm eating when I can hold it down . At least 6 to 7 times a day snacking alot mostly. Today is the first time I've been able to eat a meal and hold it down . Is it normal not to be show ? The morning sickness is getting better by the day . This is baby number two for me . With my first I was showing at this time . I'm just concerned is all.
