Week 34 Pregnancy

Third Trimester

You are 34 weeks pregnant and in your third trimester. Your baby is about the size of a cantaloupe melon. This week's key development: Ready for the World (Almost). NHS note: Midwife appointment (34 weeks).

Baby's Development

Your baby is about the size of a cantaloupe melon.

Ready for the World (Almost) — Your baby's central nervous system and lungs are maturing rapidly. Babies born at 34 weeks generally do very well with some extra care. The vernix coating is thickening, and your baby is continuing to practise breathing movements every single day.

Practical Advice for Week 34

Nutrition

  • Continue vitamin D daily.
  • Your baby's nervous system and lungs are maturing — good nutrition supports this.
  • Eat foods rich in vitamin C (citrus, berries, peppers) for your immune system.
  • Stay well hydrated to reduce swelling and Braxton Hicks.

Exercise

  • Gentle walking and birth ball exercises are ideal now.
  • If pelvic girdle pain is severe, ask for a physiotherapy referral.
  • Swimming provides wonderful relief from the heaviness of late pregnancy.
  • Continue pelvic floor exercises — they aid recovery after birth.

Wellbeing

  • If you notice sudden swelling in your face, hands, or feet, call your midwife immediately — it can indicate pre-eclampsia.
  • Vision changes (blurriness or flashing lights) should also be reported urgently.
  • Fatigue is heavy — rest without guilt.
  • Practice the breathing techniques you've learned — they'll serve you well in labour.

Preparation

  • Midwife appointment at 34 weeks — discuss signs of labour and when to call.
  • Know your hospital's phone number and when to ring the labour ward.
  • Ensure your birth partner has a copy of your birth plan.
  • Prepare freezer meals — your future self will thank you.
