Start timing contractions when they become regular and painful. Early contractions may be irregular and mild - these are often Braxton Hicks contractions. True labor contractions become progressively stronger, longer, and closer together.

Time from the start of one contraction to the start of the next (frequency), and measure how long each contraction lasts (duration). Use our timer by pressing 'Start' when a contraction begins and 'End' when it stops. The tool automatically calculates intervals and averages.

The general rule is 5-1-1: contractions 5 minutes apart, lasting 1 minute each, for at least 1 hour. However, always follow your healthcare provider's specific instructions, as this can vary based on your pregnancy history, distance from hospital, and risk factors.

Early labor: contractions 5-20 minutes apart, lasting 30-45 seconds. You can usually talk through them. Active labor: contractions 3-5 minutes apart, lasting 45-60 seconds. They're stronger and require your full attention. Transition: contractions 2-3 minutes apart, lasting 60-90 seconds.

Time contractions for about an hour to establish a pattern, then you can check periodically. Once in active labor, you may want to focus on breathing and comfort rather than timing every contraction. Your support person can help with timing.
