Outcome Measures
Primary Outcomes (1)
fetal actual birth weight
fetal actual birth in grams
immediately after delivery
Interventions
An ultrasonographic estimate will be performed in our ultrasound unit and a calculation by the ultrasound machine is based on Hadlock's formula including measurement of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL).
A clinical weight estimate will be performed by using Leopold's maneuvers
the pregnant woman will tell her subjective estimation of fetal weight estimation
