How will I know I am in labour?

There might be several signs that labour might be starting, they can happen in any order and you may not experience all of them.

As a guide you may have:Active birth - Labour and birth

  • A show; this is a sticky plug of mucus that is a protective layer within your cervix. It is sometimes slightly blood-stained and may come away gradually over more than one day but does not mean labour is imminent. If the blood is red and runny you need to phone for advice.
  • Your waters may break; this may be a sudden gush or a trickle over time. Wear a sanitary pad so you are able to monitor it. If it is not clear fluid or has an unpleasant smell phone the hospital for advice. Amniotic fluid is normally a pale straw-coloured fluid. If you are unsure that your waters have broken it is always best to phone for advice.
  • You may experience backache or a period-type of pain.

Labour is normally divided up into different stages but everyone is different. Women often ask, 'How will I know I am in labour?'. If you are unsure or worried please phone for advice.
