Your baby at 24 weeks
The lungs and brain continue developing rapidly. The baby remains small and needs substantial further growth.
Babies born this early need specialist neonatal care. Outcomes depend on many individual factors.
TRIMESTER 2 · WEEK 24
24 weeks pregnant
An important stage of development.
What to expect at 24 weeks pregnant: your baby, your symptoms and this week’s reminders.
Symptoms at 24 weeks pregnant
- You may notice a clearer movement pattern.
- Heartburn and back discomfort may occur.
- Your feet may feel tired or swollen.
None of these symptoms is required. Symptoms alone cannot diagnose pregnancy or establish your baby’s wellbeing.
If you have felt no movements by this week, tell your care team. Reduced or changed movements need immediate contact.

Measurement note: early lengths are head-to-bottom; from week 20 they are head-to-heel. The numbers across that change should not be compared as if the measurement method were the same.
