Contraction Timer

How to Time Contractions

Timing contractions is an important skill during late pregnancy. A contraction starts when your uterus begins to tighten and ends when it relaxes. You'll want to track two things: the duration of each contraction (how long it lasts) and the interval between contractions (time from the start of one to the start of the next).

Start this timer when you feel a contraction beginning, and stop it when the contraction ends. The tool will automatically calculate intervals between contractions and provide real-time analysis of your pattern.

The 5-1-1 Rule

The 5-1-1 rule is a widely used guideline to help determine when to go to the hospital. It means: contractions every 5 minutes, lasting 1 minute each, for at least 1 hour. When your contractions follow this pattern consistently, it's generally time to contact your healthcare provider or head to the hospital.

However, every pregnancy is different. Some doctors recommend the 4-1-1 or 3-1-1 rule, especially for second-time mothers who may progress faster. Always follow your healthcare provider's specific instructions.

Types of Contractions

Braxton Hicks contractions are irregular practice contractions that typically don't increase in intensity. They're common from the second trimester onward and usually go away with rest or hydration.

Early labor contractions become more regular and may last 30-60 seconds with intervals of 5-20 minutes. This phase can last several hours.

Active labor contractions are strong, regular, and close together (every 3-5 minutes), lasting 45-60 seconds or more. This is typically when you should be at the hospital.
