Preparing for Labour

Pre‑labour and True Labour

What is the difference between pre‑labour and true labour?

It is easy to confuse pre‑labour with true labour. You may have uncomfortable contractions in pre‑labour, but they are different from the contractions in true labour:

Pre‑labour

True‑Labour
  • Contractions are at irregular intervals; e.g., every 5 to 15 minutes.
  • Contractions occur at more regular intervals; e.g., 5 to 10 minutes apart.
  • Contraction length varies; e.g., lasting 20 seconds to 90 seconds
  • The length of contractions usually increases; e.g., lasting 30 to 60 seconds
  • Although they may be painful, the strength of contractions remains the same or may lessen.
  • Intensity of contractions gradually increases, becoming progressively more painful.
  • Contractions are often felt in the lower abdomen.
  • Contractions can be felt in the abdomen, across the lower back, and sometimes in the thighs.
  • You may find that contractions are most uncomfortable when you are moving and lessen when you are resting.
  • Contractions do not decrease when you are resting, but continue regardless of what you are doing.
  • The cervix usually remains closed.
  • The cervix thins and shortens (effaces) and opens (dilates).
  • There is no “show” (pink‑tinged vaginal mucus).
  • There may be “show” and/or fluid leaking from your amniotic sac.
What should we do if we are not sure if it is pre‑labour or true labour?
  • If it’s night, try to sleep. You want to be well rested for childbirth. In true labour you may not be able to sleep but will at least rest. If you fall asleep, it is most likely pre‑labour.
  • Take a shower. The contractions in pre‑labour will often become less frequent and shorter. In true labour the contractions will continue no matter what you are doing.
  • Distract yourself. Watch a movie, walk in the garden, play cards. If you are in true labour, the contractions will demand your attention. If it’s pre‑labour, you may be able to carry on with your usual routines.
When should we call our health care provider or hospital?
  • When your contractions are regular and painful, last 30 to 60 seconds, and happen at 5 minute intervals.
  • If your water breaks (amniotic sac).
  • If you have vaginal bleeding or show (pink‑tinged vaginal mucus).
  • If you are unsure and have concerns.
  • If you health care provider has advised you to call early.
  • If your baby seems to have stopped moving or moves less than usual.

If you’re not sure and can’t reach your health care provider by phone, call HealthLink BC at 8‑1‑1. That way you can speak with a registered nurse who can give you helpful information and advice when you need it most.
