3D ultrasound at 29 weeks

Ay

So I went today to get my 3D ultrasound with my family. I’m 29 weeks and I was curious so I asked approximately how much she weighed. (Yes it’s a girl!) so we all guessed. About 2 pounds and some change. BABY GIRL IS COMING UP 3 POUNDS AND 4 OUNCES. Is that normal ? I feel like she’s going to come early like 36 weeks.
