Your baby

Your baby is around 16.4cm long now. Their hair is starting to grow – as are the nerves in the brain that control smell, hearing, taste and touch.

Abdominal organs such as the stomach, liver and intestines are now fully encased in the abdominal cavity.

Your little one’s tooth buds for their milk teeth are now in place. By now, on your ultrasound, their spine will also appear quite straight.

You

Congratulations, as a 20 week pregnant mum-to-be, you’re halfway through your pregnancy! You may feel aches in your abdomen as your uterus continues to grow – and could start to notice some backache or occasional leg cramps.

You may have noticed a number of changes in your body that affect the way you move and exercise. 20 weeks pregnant weight gain and the change in your centre of gravity are likely to affect your posture. Regular gentle exercise will help this and alleviate stress.

From this week a lot of women start to feel the first kick. It may feel like butterflies in your tummy. Most of your baby’s movements will be reflexes but they will be exploring their surroundings freely with their hands and feet.

If you’re finding sex is becoming difficult try some new positions. Find out more about sex during pregnancy.
