Small Tummy

Hi mummies. I'm currently 37+4. My height and weight is abt 170cm / 90kg. Baby is currently 2.9kg during my scan last friday. But I've received a lot of comments from colleagues and even strangers saying that my tummy is small. I'm trying to console myself by telling myself that maybe my hips are just big and that baby is more nestled inside so the tummy doesnt seem that big. Have any one you ever experienced this? Any of you with full term babies born 2 kg plus?
