Belly, Belly, No Belly?

Gabrielle
I See So ManyPeople With Nice Sizes Belly, I'm Just So Little I Barely Have Anything, I'm Wonder When Will I Pop? I'm 18 weeks It's My First Baby.. Anyone Else Feeling The Same Way? Like I Go To My Doctors Or When People Ask They Are Shocked That I Am Even Pregnant And As Far Along As I Am..
