How do you use a contraction timer?
Start the timer when a contraction begins and stop it when the contraction ends. The app records duration and the interval before the next entry. Do not pressure yourself to keep logging when it is difficult or uncomfortable to do so.
Discuss in advance when to contact your maternity team. A generic online rule should not replace your personal plan.
Do regular contractions always mean the same thing?
The pattern, intensity, and accompanying symptoms may require clinical assessment. The timer only calculates times you mark; it cannot distinguish true from false labour and does not measure uterine activity.
When should you not wait for a timer pattern?
If you think your waters have broken, have vaginal bleeding, notice reduced fetal movement, experience severe or unusual pain, or are worried for any reason, do not wait for a particular timer pattern. Contact your maternity team or the urgent health service they have provided.
Medical information boundary
A contraction timer does not diagnose labour. For suspected waters breaking, bleeding, reduced fetal movement, severe pain, or concern, contact your care team without waiting for a timer result.
Common questions
Frequently asked questions
Can a contraction timer tell me labour has started?
No. It only records the duration and intervals of contractions you mark. A clinical decision about labour requires assessment by healthcare professionals.
When should I start timing contractions?
You can record them when you want help remembering their timing. Use your personal maternity plan to decide when to contact your care team.
Is timing still useful when contractions are irregular?
A dated record may be a useful prompt during a conversation, but regularity alone does not diagnose labour. Seek professional support without waiting for a timer result if you are concerned.
