How Much Does Your Baby Weigh?

Feeboo
Hi Ladies!
Currently 33 weeks pregnant and due 6/16/15 with a little boy. He has been behind on his growth, especially his weight since our first ultrasound. A lot of the technicians have a hard time measuring because he moves a lot during the measurements. The doctors are taking extra precautions and I see them Monday and Thursday's for appointments. He is currently 4 lbs. Has anyone had this issue? I am soooo worried and this is my first. Anyone have this happen?
