Week 16

Your baby

The muscles of the baby's face can now move and the beginnings of facial expressions appear. Your baby can't control these yet.

The nervous system continues to develop, allowing the muscles in your baby's limbs to flex. Around this time, your baby's hands can reach each other – they can form a fist, and hold each other when they touch.

You

If you've been feeling sick and tired with morning sickness, you'll probably start to feel better when you're around 13 or 14 weeks pregnant.

Some women start to experience an increased sex drive around this time, possibly due to pregnancy hormones or increased blood flow to the pelvic area. Some women don't, and this is perfectly normal. You can find out more about sex in pregnancy.

You'll notice a small bump developing as your womb grows and moves upwards. If you've been feeling the urge to pass urine more often over the last few months, it's because your womb was pressing on your bladder. This should ease off now.

See your doctor if you notice any pain when you urinate. Urinary infections can happen in pregnancy and it's important to treat them quickly to reduce the risk of kidney infections.
