Can someone explain ? I’m confused

I had a appointment today with my GYN and they wanted to measure the baby and all. So I’m 30w and 6d , baby’s weight is 2lbs 13oz , glow says baby should weight 2.9lbs around this time

So it looks like my baby is weighing how she should be . The doctor however told me that the baby is measuring small for a 30+week fetus.

I’m confused

Is the baby measuring small in weight?
