I had an u/s this morning & I know its not 100% at giving you an idea on the size of the baby. BUT I was wondering, if the messurments (HC, abdoCirc etc) are all pretty spot on seems they actually messure these things. So what I want to know, Could she be smaller then what she thinks or only bigger? She thought she was about 8 & half pounds. I am assuming thats going off the messurements.
