Near the due date, it helps to tell the difference between early labour and practice contractions. These are the signs described in WHO materials.

Time to go in

• Regular painful contractions every 20 minutes or less. True contractions do not stop when you change position and gradually become stronger and closer together
• Your waters have broken, even if contractions have not started. A noticeable leak of clear fluid is a reason to go in
• Bloody mucus discharge ("show")

If you live far from the hospital or birth centre, leave at the first signs rather than waiting for contractions to become more frequent.

Practice contractions: how to tell

Braxton Hicks contractions are irregular, painless or mildly uncomfortable, and often settle with walking, changing position, or resting. They do not become steadily stronger and closer together.

Go immediately, without waiting for regular contractions, if:

• You have bleeding
• Contractions start or your waters break before 37 weeks
• The baby is moving noticeably less
• You have a severe headache, vision changes, or convulsions
• You have severe ongoing abdominal pain

If you reach 41 weeks and labour has not started

See your doctor. They will assess the baby's wellbeing and discuss the next steps, such as continued monitoring or preparing for birth.

If you are unsure, call your maternity hospital or birth centre. It is better to come in early than late.
