Signs of Labour: How to Know It Is Time

The signs that labour is starting, what each one means, and when to contact your maternity unit or go in.

Labour can start slowly over days or quite suddenly. Knowing the signs helps you decide when to call your care team.

Early signs that labour may be close

  • A show: the plug of mucus that seals the cervix comes away as a thick, jelly-like discharge, sometimes streaked with blood. Labour may still be hours or days away.
  • Backache or period-like cramps that come and go.
  • Needing to open your bowels more often, as the baby’s head presses down.
  • The baby dropping lower into your pelvis, which can make breathing easier.

Signs that labour has started

  • Regular contractions that get longer, stronger and closer together, and do not go away when you rest or move.
  • Your waters breaking: a gush or a steady trickle of fluid from your vagina. Waters are usually clear or pale pink.

The stages of labour

  1. Early (latent) labour: contractions start and the cervix softens and begins to open. This can last many hours, especially with a first baby.
  2. Active labour: contractions are strong and regular and the cervix opens to 10 cm.
  3. Pushing and birth of the baby.
  4. Delivery of the placenta.

When to contact your maternity unit

Follow the plan your care team gave you. Contact them straight away if:

  • your waters break, especially if the fluid is green, brown or smells unpleasant
  • you have bleeding from your vagina
  • your baby is moving less than usual
  • you have constant, severe tummy pain
  • you are less than 37 weeks pregnant and think labour has started
  • contractions are regular and strong, as advised for your situation
