Frequently Asked Questions

What is a contraction timer?

A contraction timer helps track the duration (how long each contraction lasts) and frequency (time between contractions) during labor. It helps you and your healthcare provider understand your labor progression and decide when to go to the hospital.

How do I use this contraction timer?

When you feel a contraction starting, tap the "Start Contraction" button. When the contraction fades, tap "Stop". The tool automatically records the duration and calculates the interval since your last contraction. Repeat for each contraction to track your pattern.

What is the 5-1-1 rule?

The 5-1-1 rule is a guideline for when to go to the hospital: contractions every 5 minutes, each lasting 1 minute (60 seconds), and this pattern continuing for at least 1 hour. This tool automatically detects when your pattern matches this rule and alerts you.

Braxton Hicks vs. True Labor Contractions

Braxton Hicks (false labor) are irregular, usually painless, and don't get closer together. True labor contractions become progressively more regular, longer, stronger, and closer together over time. True contractions also don't stop with rest or hydration.

When should I call my doctor or midwife?

Call your healthcare provider if: contractions are regular and increasing in intensity, your water breaks, you experience heavy bleeding, you notice decreased fetal movement, or you have any concerns. Always follow your provider's specific guidance, especially if you have a high-risk pregnancy.

How long do early labor contractions last?

In early labor, contractions typically last 30–45 seconds and may be 5–20 minutes apart. As labor progresses into active labor, they lengthen to 45–70 seconds and come every 2–5 minutes. Every person's labor is unique—use this timer to track your personal pattern.

Is my data saved if I close the browser?

Yes. Your contraction history is automatically saved to your browser's local storage. If you close the tab and return later on the same device, your records will be restored. You can also manually clear all data using the "Clear All" button.

What is the difference between contraction duration and interval?

Duration is how long a single contraction lasts (from start to end). Interval (or frequency) is the time from the start of one contraction to the start of the next. Both metrics help assess labor progression and regularity.

Can I use this timer during active labor?

Absolutely. The large, easy-to-tap buttons are designed for use even during intense contractions. The timer provides clear visual feedback and the interface is optimized for mobile devices. However, always prioritize your comfort and safety—have a partner help if needed.
