Pregnancy week 22

Your baby’s development

At 22 weeks your baby is about the size of a cucumber. The focus this week is the sense of touch: nerve endings in the skin are developing, and your baby explores the surroundings by touching its own face, the cord and the wall of the womb. The eyes are fully formed, but the iris has not yet taken on its colour; eye colour becomes clearer after birth. Lips, eyebrows and hair look more distinct. Tooth buds form beneath the gums. The pancreas continues to build the hormone-making ability the baby will need later. Your baby moves arms and legs deliberately, and sometimes grips itself and lets go. Movements can be more frequent and stronger now. Your baby may also react to sounds, especially your voice. Measurements are averages. Development moves at its own pace in every pregnancy; your doctor interprets ultrasound measurements, and small differences are usually ordinary.

Changes in the mother

You may sometimes feel brief, painless tightening in the belly. These are known as Braxton Hicks contractions and are part of the womb preparing for pregnancy. They are usually irregular and ease with rest or a change of position. Mild swelling of the feet and hands can appear; rings or shoes feeling tight may be a sign. Changes in hair and nails are common as well. In these weeks, finding a sleeping position gets harder as the belly grows. Lying on your side and propping yourself with pillows works for most people. Be sure to drink enough in warm weather. If the tightenings become regular, grow more frequent, turn painful, or come with pressure in the back or groin, contact your doctor or the nearest health facility.

To do this week

• Make sure the detailed ultrasound has been done (usually weeks 18–22/23).
• Learn the signs of regular, painful contractions and talk to your doctor.
• Find out about the leave and rights available to you during pregnancy.
• Make your sleeping position comfortable with a support pillow.
