Your maternity care provider has referred you for an ultrasound scan to assess the baby’s size and the amniotic fluid volume. This type of ultrasound scan is referred to as a fetal growth scan.
What is a growth scan at 35 weeks?
The scan reveals the position of your baby in the womb which usually stabilises from around 36 weeks into your pregnancy. Your sonographer will be able to see whether your baby is in the normal position (head down), breech position (feet first) or lying sideways (transverse position).
What is considered a big baby at 35 weeks?
What is a big baby? The medical term for big baby is macrosomia, which literally means “big body.” Some researchers consider a baby to be big when it weighs 4,000 grams (8 lbs., 13 oz.) or more at birth, and others say a baby is big if it weighs 4,500 grams (9 lbs., 15 oz.) or more (Rouse et al. 1996).
Are growth scans at 38 weeks accurate?
Scans done at 40 weeks and beyond were more accurate than those done preterm. Only 81% of the scans done between 34 and 37 weeks gestation fell within the accepted 15% margin of error between EFW and actual weight compared to 100% when the scan was done after 40 weeks.
Why do I need a growth scan at 38 weeks?
If you have a scan in your third trimester, it will probably be to check how well your baby is growing. Your midwife may suggest that you have a scan if she thinks your baby is smaller than expected for your stage of pregnancy.
What happens if growth scan shows big baby?
If the scan shows that your baby’s size is above the 90th centile line then it is confirmed as an LGA baby. There is no need to have further scans after 37 weeks. This is because the ability of a scan to predict the correct weight of your baby is reduced as your baby grows and you get nearer to your due date.
What are the signs of a big baby?
A larger than expected fundal height could be a sign of fetal macrosomia. Excessive amniotic fluid (polyhydramnios). Having too much amniotic fluid — the fluid that surrounds and protects a baby during pregnancy — might be a sign that your baby is larger than average.
What happens if baby measures small at 38 weeks?
But most babies who are small for gestational age have growth problems that happen during pregnancy. Many of these babies have a condition called intrauterine growth restriction. This happens when the unborn baby doesn’t get the nutrients and oxygen needed to grow and develop organs and tissues.
Why has my baby’s growth slowed down?
Growth restriction early in pregnancy (early onset) happens because of chromosome problems in the baby. It also happens because of disease in the mother, or severe problems with the placenta. Growth restriction is called late onset if it happens after week 32 of the pregnancy. It is often linked to other problems.
Is baby still growing at 38 weeks?
Your baby is still growing and filling the womb – but this doesn’t mean that their movements should slow down. If baby is not moving as much as they were, or if you’re worried about their movements for any reason, talk to your midwife or doctor immediately.
Why do I need a growth scan at 39 weeks?
Your provider might request an ultrasound during these final weeks to confirm your baby’s positioning, gestational age, or any number of factors that could influence how and when you deliver your baby. At this point your baby should be positioned with his head down and moving down further into the pelvis.
When do you need a growth scan for Your Baby?

What does the sonographer see on a third trimester growth scan?
Your sonographer will be able to see whether your baby is in the normal position (head down), breech position (feet first) or lying sideways (transverse position).
What should be included in a fetus growth chart?
This should include at least two fetal measurements (usually biparietal diameter (BPD) and femur length (FL)) plus a consideration of additional parameters such as head circumference (HC), occipitofrontal diameter (OFD), abdominal circumference (AC) and humerus length (HL).
Is it possible to predict gestation at 20 weeks?
The reduced accuracy of prediction of gestational age after 20 weeks must be appreciated. At any gestation, if the ultrasound fetal measurements of each parameter are not in agreement, the reason for this difference should be evaluated. This is preferable to just averaging all values to arrive at an estimated gestational age.
