Week 21 is a wonderful time for you and your developing baby. This educational guide will give you important details about what to anticipate throughout this phase and how to get you ready for the upcoming weeks.

Your baby is around 26.7 cm long from head to toe and will weigh around 350g.

The baby’s digestive system is developing, and they may begin to swallow small amounts of amniotic fluid. The baby’s movements become more coordinated and stronger, and you may feel them moving more frequently. Your baby’s skin is still transparent, and blood vessels are visible underneath.

Your baby can now hear noises and voices outside the womb.

As a result, your baby is now heavier than the placenta. By providing food and removing waste, the placenta serves as both a larder and toilet. During your pregnancy, it will continue to grow to perform its vital functions. When you can, take naps to make up for the sleep you missed at night.

You can experience lower back, hip, and leg pain as your body continues to adapt. Stretch marks may begin to appear as your skin stretches to make room for your expanding baby.

During week 21, a thin coating of hair known as “lanugo” has been growing. Its function is likely to maintain your baby at the ideal temperature and typically disappears before birth. Your baby is also developing hair and eyebrows.

Routine blood tests and urine tests will be performed to monitor your health and screen for potential issues. As with any appointment, this is a great opportunity to discuss any concerns you have with your healthcare provider.

Week 21 is an exciting time in your pregnancy journey as you continue to bond with your growing baby. By staying informed and taking care of yourself, you’ll ensure the best possible health for you and your baby.

We hope this guide provided you with some insight into what you can expect this week.
