How to use the contraction timer

Simply press the blue start button to begin timing your contraction. When the contraction ends press the button again. The button is red when a contraction is in progress.

This is how you record each individual contraction.

Info for contraction analysis

Labour is described in three stages, and together these stages complete the delivery. In the first stage the cervix gradually opens up (dilates). The second stage is the actual birth of your baby. The third and final stage is the delivery of the placenta.

First stage: dilation of the cervix
Second stage: birth of your baby
Third stage: delivery of the placenta

You can use the contraction timer to measures the contractions within the first stage of labour.

The first stage of labour is itself split into yet another three separate phases:

1. Early phase

Contraction interval: 5-30 mins
Duration contractions: 30-60 sec
Dilation: 0-3 cm / 0 - 1.5 ”
Duration: 8-12 hours

2. Active phase

Contraction interval: 3-5 mins
Duration contractions: 45-60 sec
Dilation: 4-7 cm / 1.5 - 3 ”
Duration: 3-5 hours

3. Transition phase

Contraction interval: 30 sec - 3 mins
Duration contractions: 1-2 mins
Dilation: 8-10 cm / 3 - 4 ”
Duration: 30 mins - 2 hours
