Contraction timer

Tap when a contraction starts and again when it ends. The timer works out how long each one lasts and how far apart they are.

Call now, whatever the timer shows, if your waters break, you have bleeding, your baby's movements change, the pain is severe or constant, you are under 37 weeks, or you are worried. Your maternity unit may give different advice from the 5-1-1 guide, so follow what they told you.

How to time contractions

Time from the start of one contraction to the start of the next. That is the gap between them.
Also note how long each one lasts, from when it starts to when it fades.
In true labour, contractions usually become longer, stronger and closer together, and they do not ease when you rest or change position. Braxton Hicks tightenings are irregular and usually settle.

When to call

Many maternity units suggest calling when contractions are regular, about 5 minutes apart or closer, and last about a minute, for around an hour (the 5-1-1 guide). Advice varies, so follow what your own unit has told you, and call earlier if you are anxious or live far from the hospital.

Call straight away if your waters break, you have bleeding, your baby's movements change, the pain is severe or does not ease between contractions, you are less than 37 weeks pregnant, or you are worried. Read more in our guides to the signs of labour and the stages of labour.
