Timing Contractions - What You Need to Know.

Accurately timing contractions is the key to understanding what your contractions meanare they just Braxton Hicks? A false alarm? LABOR??!!!

And the key to accurately timing contractions is to know how long each contraction lasts, how far apart they arrive, and how long you’ve been feeling them.

Simple enough, right?

If you answered “No”, you are in good company! We hear that all the time.

Here are some simple rules and definitions to help you accurately time your contractions: 

 

The basics of timing contractions

First, you’ll need to note three time points: the start of a contraction, the end of a contraction, and the start of the next contraction.

Terms for timing contractions:

 

Duration of a contraction – “How long are they lasting?”

Duration is measured from the beginning of one contraction to the end of that contraction.

Time the duration of a contraction by starting your timer when a contraction starts and stopping the timer when the contraction ends. Somewhere in the middle, you’ll feel a peak in intensity but wait until all sensation has stopped before you stop the timer.

Frequency of contractions – “How far apart are they?”

Frequency is based on the time between the start of one contraction and the start of the next contraction.

Time the frequency of contractions by noting the time when one contraction starts and the time when the next contraction starts. Some apps will do this math for you when you are working to time the duration. The Bloomlife contraction monitor will automatically record it for you.

The 5-1-1 Rule – all three questions

The 5-1-1 rule also takes into account the “How long have you been feeling them?” since contraction patterns should be recorded for at least one hour. This rule of thumb often comes from your care team and/or birth educator as a way to know when early labor becomes active labor. It may take many forms, you may hear 4-1-1 or 3-1-1, so talk with your care team about their specific recommendations.

Timing for 5-1-1 stats is based on frequency of contractions (specifically the actual interval between) becoming 5 minutes apart, on average, duration of your contractions becoming 1 minute long, on average, and timing continuing over one hour.

What else should I look for when timing contractions?

We’re glad you asked!

Stats are usually only important once contractions have become regular in their pattern. Regularity is important since stats take the average of each contraction duration and interval (frequency).

 

Irregular contraction patterns

An irregular pattern typically indicates Braxton Hicks contractions, those sporadic warm-up or “false labor” contractions.

Regular contraction patterns

A regular pattern can indicate early labor.  Contractions during this stage start to sync up and get the body ready to push out that baby.

Progressing contraction pattern

Progression means contractions get closer together. It may signify cervical change (which only your doctor can assess!) as your body really kicks into labor mode.

So, now how do I actually time contractions?

This is where contraction timers come in. There are 50+ apps in the app store that act similar to the stopwatch function on your phone but may also track and display the contraction pattern and timing and don’t require you to do the math.

A better, and more accurate way is to use a smart contraction tracker, like Bloomlife. Bloomlife automatically tracks, times and counts contractions by monitoring your uterine muscle activity as it contracts. It does all the contraction timing for you – monitoring the start of each contraction, the end of each contraction, displaying the contraction pattern, and calculating the stats you’ll need for your 5-1-1 rule.  No stopwatch required!
