Bump to small

Edit: went for my 31 week check up today and the dr is having me get another scan in 2 weeks…..she said she’s not concerned but when she left i heard her say my measurements were on the small side……can everyone say a little prayer that little man is just hanging towards my back.

I’m getting a little concerned I’ll be 31 weeks in two days with my second. I was huge with my 1st son but i feel like i don’t look 7 months pregnant. Does anyone else have a smaller bump with their second? My dr said this one could be smaller but ultrasound measured him large 😩.
