How It's Calculated

Key Metrics

  • Duration: Time from Start to Stop
  • Frequency: Time between contraction starts
  • Average Duration: Mean of all durations
  • Average Frequency: Mean time between contractions

Labor Stages

  • Early Labor: Contractions 5-30 min apart, 30-45 sec
  • Active Labor: Contractions 3-5 min apart, 45-60 sec
  • Transition: Contractions 2-3 min apart, 60-90 sec
Example: Contraction #1: 45 sec, #2: 50 sec (3 min apart) → Active Labor Stage. Average duration: 47.5 sec, Frequency: 3 min.

About Contractions & Labor

What are Contractions?

Contractions are the tightening and relaxing of the uterine muscles during labor. They help push the baby down the birth canal. Timing contractions helps you understand your labor progression — when they become regular, longer, and closer together, it's a sign that active labor is approaching.

When to Go to the Hospital:

  • Active Labor: Contractions 3-5 min apart, 45-60 sec long
  • Transition: Contractions 2-3 min apart, 60-90 sec long
  • Water Breaks: Call your healthcare provider immediately
  • Bleeding: Any heavy bleeding requires immediate attention

Frequently Asked Questions

Start timing when you notice regular contractions that are becoming more consistent. Early contractions may be irregular — start timing when you feel they are getting into a pattern. Use this tool to track duration and frequency to help determine your labor stage.
The general guideline is to go to the hospital when contractions are 3-5 minutes apart, lasting 45-60 seconds, and have been consistent for at least 1 hour. However, always follow your healthcare provider's specific instructions, especially if your water breaks or you experience any concerning symptoms.
Early labor (latent phase) is characterized by mild, irregular contractions that are 5-30 minutes apart and last 30-45 seconds. Active labor is when contractions become stronger, more regular (3-5 minutes apart), and last 45-60 seconds. Active labor typically starts when the cervix is dilated to about 6 cm.
This timer measures duration and frequency based on your inputs. The accuracy depends on how precisely you press Start and Stop. It's a helpful tracking tool, but it should not replace professional medical monitoring.
Transition is the most intense phase of labor, occurring when the cervix dilates from 8 to 10 cm. Contractions are very strong, 60-90 seconds long, and occur every 2-3 minutes. This phase is usually the shortest but most challenging part of labor.
