Baby measuring big

Ryan

My wife and I just had a ultrasound and our daughter is measuring a week and half bigger

April we got a ultrasound at 12 weeks and the doctor said baby was growing 2-3 days ahead of schedule. Now that we went to a ultrasound yesterday at 16 weeks and 6 days the doctor said our baby is growing a week and 4 days a year of schedule! My question to you all, what do my wife and I go off being 17 weeks today or being 18 weeks and 5 days today.
