Am I too small?

Jonai
I'm 23+4 weeks and all I keep hearing is your so small? Someone even said that they think I'm malnourished and not eating correctly. I've always had good eating habits. No red meats, tons of Fruits and veggies. Now I occasionally pig out but greasy foods make me quesy and that was before I got pregnant. My dr said in fine and baby is healthy. Anyone else carrying really small?
