At week 20, your doctor may have already discussed with you about your baby’s anomaly scan. Many choose to undergo this procedure, since it specifically checks for any gross abnormalities in your baby’s development.

Though a bit unnerving, it is wise for your baby to undergo an anomaly scan at week 20, though some doctors may schedule it a bit later. It is at this stage when the organs can be clearly visualized.

Early detection of gross anomalies allows you and your partner to make quick interventions that can potentially save your pregnancy, or make decisions that will be best for you and your baby.

Typically, a congenital anomaly scan is a comprehensive ultrasound scan of your baby, which measures the head, chest, abdomen, legs, fingers and toes. It also checks your baby’s eyes, nose, mouth, heart (and its chambers), lungs, diaphragm, kidneys, buttocks and spine.

A congenital anomaly scan also measures how much amniotic fluid you have. Too much or too less is not good for your baby. This procedures generally takes longer than the usual ultrasound scan, but don’t worry - your doctor will walk you through it all the way.
