No, the growth scan is a painless and non-invasive procedure. You may feel mild pressure from the ultrasound probe, but it should not cause any discomfort.

While the estimated fetal weight is an important indicator, it is not 100% accurate. There can be a variation of about 10-15% in the estimated weight compared to the actual birth weight. However, it provides valuable information for assessing the baby's growth trend.

The scan typically takes about 20 to 30 minutes. The duration may vary depending on factors like the baby's position and the specific measurements needed.

If the scan indicates concerns about the baby's growth, your healthcare provider may recommend additional monitoring, such as follow-up ultrasounds, Doppler studies, or non-stress tests. In some cases, early delivery may be considered to ensure the baby's safety.
