Pregnancy Week 21
Your baby is continuing to grow and become more active this week. The digestive system is developing, movements are becoming stronger, and your baby is gradually gaining more body mass as the second half of pregnancy progresses.
Your Baby This Week
Movement & Digestion
At week 21, your baby is becoming increasingly active. The muscles and nervous system are working together more effectively, allowing your baby to kick, stretch, turn, and move the arms and legs.
The digestive system is also continuing to develop. Your baby regularly swallows amniotic fluid, which helps the digestive system practice its functions.
Taste Buds & Swallowing
Your baby’s taste buds are developing, and swallowing movements are becoming more coordinated.
The amniotic fluid surrounding your baby can contain tiny amounts of substances from your diet, allowing your baby’s developing taste system to experience different flavors.
Growing Body
Your baby’s body continues gaining size and becoming more proportional. The bones and muscles continue strengthening, while the skin remains relatively thin.
Moving & Growing
Your baby is about the size of a banana. The muscles, nervous system, and digestive system continue developing as your baby becomes more active.
Your Body This Week
Your body continues adapting as your baby grows and your uterus expands.
Stronger Baby Movements
You may notice your baby's movements becoming stronger and easier to recognize. Kicks and stretches may occur at different times throughout the day.
Growing Belly
Your uterus continues expanding, and your growing belly may affect your posture and balance.
Heartburn & Indigestion
Hormonal changes and the growing uterus can contribute to heartburn, bloating, or indigestion.
Leg Cramps
Leg cramps can occur during pregnancy, particularly at night. Gentle stretching, movement, and adequate hydration may help.
