Depending on the baby’s position inside the uterus, you’ll be able to find out if you’re expecting a little boy or a girl during the 20-week scan (morphological ultrasound.)

Your baby will measure around 15 centimeters in length. Now you can also listen to its little heartbeats and sounds produced by their digestive system.

On the 18th week begins the production of the meconium or the baby’s first feces. It’s sticky, thick, and dark green and is typically passed in the womb during early pregnancy and then again in the first few days after birth.

You’ll see it during the baby’s first diaper change, which is a result of the combination of amniotic liquid, dead cells, and secretions from the baby’s intestines.

Another important bit of information is that your baby is now developing its future fingerprints.
