Week 24 Pregnancy

Second Trimester

You are 24 weeks pregnant and in your second trimester. Your baby is about the size of an ear of corn. This week's key development: Viability Milestone. NHS note: Midwife appointment to check blood pressure, urine, and baby's growth.

Baby's Development

Your baby is about the size of an ear of corn.

Viability Milestone — This week marks an important threshold — babies born from 24 weeks have a chance of survival with specialist care. Your baby's face is almost fully formed, and they're practising breathing movements with their lungs. A moment worth acknowledging with gratitude.

Practical Advice for Week 24

Nutrition

  • Continue vitamin D daily.
  • If you're having a glucose tolerance test (GTT), you'll need to fast beforehand — your midwife will explain.
  • Eat balanced meals with lean protein, complex carbs, and vegetables.
  • Small, frequent meals help manage blood sugar levels.

Exercise

  • Regular exercise reduces the risk of pre-eclampsia and gestational diabetes.
  • If carpal tunnel tingling affects your hands, wrist exercises and splints can help.
  • Ankle rotations and foot pumps help with circulation.
  • Modify exercises — use a wider stance as your bump grows.

Wellbeing

  • Week 24 is the viability milestone — a moment worth acknowledging with gratitude.
  • Itchy skin on your bump is normal — moisturise regularly.
  • Leg cramps can be helped by stretching, hydration, and magnesium-rich foods.
  • If itching is severe (especially on palms and soles), tell your midwife — it could be ICP.

Preparation

  • Midwife appointment to check blood pressure, urine, and baby's growth.
  • If you're at risk of gestational diabetes, a GTT will be offered around now.
  • Start thinking about who will look after any older children during labour.
  • Check if you need to update your car insurance for the new arrival.
