belly too small? baby not moving enough?

Hannah • mommy 💕
I'm due oct 3rd. This is my first pregnancy. I didn't find out I was pregnant until two weeks ago. I've only had one doctor appointment plus an ultrasound... the doctor said my belly was the exact right size when she measured it.. but everyone else due in oct on here has pics with their cute bellies and mines so much smaller I don't even feel comfortable trying to get a good picture of it. Also, I see a bunch of people talking about kicking... my baby doesn't seem to kick much or I just don't notice it... the doctor asked if I could feel movement and I said I think but just a little movement and she didn't seem too concerned.... I just feel like my baby is behind it too small or something's wrong
