Things will be more relaxing and calm now – your nausea subsides, your emotions upheavals take a backseat, and the best part is you can feel your baby’s first movements. Hence, the week 13 to week 27 of pregnancy is also called the “feel good period” sometimes.

What is second trimester anomaly scan in pregnancy?

The anomaly scan (ultrasound level II) is a routine ultrasound scan that is aimed to see your baby’s body and check some important details -the position of critical elements such as the placenta, the umbilical cord, the level of amniotic fluid around your growing baby, your uterus and cervix. It is also referred to as a ‘morphology scan’.
Halfway through your pregnancy, most of your baby’s organs have already developed while some are still developing.

Hence, it is important to figure out if all is well. Through the anomaly scan, the doctor will check to see if your baby has any abnormalities in growth, including in his heart, stomach, kidneys and limbs. However, while many abnormalities can be detected in this scan, not all of them can be deciphered.
