Most of the time, there’s a harmless explanation. Maybe your due date is off by a few days or a week (it’s pretty common for doctors to change due dates). Your baby could be in a funny position or sitting high in your uterus, and that’s throwing the tape measure off.
What happens if baby is measuring ahead?
Risks associated with fetal macrosomia increase greatly when birth weight is more than 9 pounds, 15 ounces (4,500 grams). Fetal macrosomia may complicate vaginal delivery and can put the baby at risk of injury during birth. Fetal macrosomia also puts the baby at increased risk of health problems after birth.
Will I deliver early if my baby is measuring big?
If a baby is too large to fit through the birth canal easily, delivery can be difficult. If ultrasound exams during pregnancy show a baby is very large, your healthcare provider may recommend early delivery.
What does it mean to measure a week ahead in pregnancy?
Pregnancy week by week
The measurement is generally defined as the distance in centimeters from the pubic bone to the top of the uterus. The expectation is that after week 24 of pregnancy the fundal height for a normally growing baby will match the number of weeks of pregnancy — plus or minus 2 centimeters.
What does it mean if your baby is measuring big?
What does it mean if I’m measuring “large for gestational age”? Measuring large for gestational age means your fundal height is more than 3 centimeters larger than expected for your stage of pregnancy, based on your due date. Your provider will probably schedule an ultrasound to find out why.
Does measuring ahead change due date?
It could be that your uterus size doesn’t sync up with the standard growth charts (i.e. you measure big). And if the measurements are off by three weeks or more, in many cases your due date is moved to reflect this.
How big of a baby can you deliver?
A: A baby that weighs more than 8 lbs 13 ounces at the time of delivery is considered a “macrosomic” or “large for gestational age” baby.

Why is my baby growing so fast in the womb?
Macrosomia occurs when a baby gets more nutrients in utero than she needs, causing her to grow faster and larger than usual.
How can you tell how much your baby will weigh at birth?
For those of you who have a thing for math, here’s the equation: Birth weight (g) = gestational age (days) x (9.38 + 0.264 x fetal sex + 0.000233 x maternal height [cm] x maternal weight at 26.0 weeks [kg] + 4.62 x 3rd-trimester maternal weight gain rate [kg/d]] x [number of previous births + 1]).
When do babies usually drop in the womb?
At the end of the third trimester, the baby settles, or drops lower, into the mother’s pelvis. This is known as dropping or lightening. Dropping is not a good predictor of when labor will begin. In first-time mothers, dropping usually occurs 2 to 4 weeks before delivery, but it can happen earlier.
