Frequently Asked Questions - Week 41
Real labour contractions follow a regular pattern: they come at consistent intervals, last 45–60 seconds each, and get progressively stronger, longer, and closer together over time. Braxton Hicks, by contrast, are irregular, don't intensify, and often ease when you change position or rest. Other labour signs include the 'bloody show' (blood-tinged mucus plug), your waters breaking, or persistent lower back pain that worsens in waves.
Follow the 5-1-1 rule: go to hospital when contractions are 5 minutes apart, lasting 1 minute each, for at least 1 hour. Go immediately if: your waters break (regardless of contractions), you have heavy vaginal bleeding, your baby's movements reduce significantly, or you develop a severe headache, vision changes, or upper abdominal pain. In Singapore, call your hospital's labour ward 24-hour line - They'll advise you.
