Second trimester

Pregnancy week 23

This week your baby is about the size of a grapefruit — around 28.9 cm and 501 g.

Your baby this week

Your baby's skin is gradually filling out as more fat is added, though it still looks a little wrinkled and see-through. The lungs are developing quickly, and blood vessels inside them are forming in preparation for breathing after birth. Your baby can hear more clearly now, including your heartbeat, the sounds of your body, and your loving voice. Movements are becoming more active, and you may feel them regularly.

Your body this week

You may notice mild swelling in your ankles and feet, especially at the end of the day or in warm weather. It's also common to feel occasional Braxton Hicks contractions, which are gentle, irregular practice tightenings. Your skin may feel more sensitive, and you might notice redness in your palms.

Tips for this week

Drink water regularly and put your feet up when resting to ease swelling. Braxton Hicks contractions are usually normal, but if they become painful, frequent, or regular, reach out to your doctor or midwife for reassurance. Take short rest breaks throughout your day to recharge.
