Contraction Pattern Calculator
Calculate contraction frequency, duration patterns, and determine labor progression stage
About this calculator
The Contraction Pattern Calculator helps expectant mothers track and analyze their labor contractions by calculating frequency, duration, and intensity patterns. This tool assists in determining which stage of labor you're in and when it may be time to contact your healthcare provider or head to the hospital. By monitoring contraction patterns, you can better understand your labor progression and make informed decisions about when to seek medical attention.
How to use
Enter the start and end times of each contraction as they occur. The calculator will automatically determine contraction duration and the interval between contractions. Continue logging contractions for at least one hour to establish a clear pattern and receive guidance on your current labor stage.
Frequently asked questions
When should I start timing contractions?
Begin timing when contractions feel regular and strong, typically when they're uncomfortable enough that you need to pause activities.
What contraction pattern indicates active labor?
Active labor typically shows contractions lasting 45-60 seconds, occurring every 3-5 minutes consistently for at least one hour.
How accurate is this calculator for determining labor stage?
While helpful for tracking patterns, always consult your healthcare provider for official labor stage assessment and medical guidance.
