Time contractions from the start of one to the next, tracking how often they come, how long they last, and how strong they feel. The 5-1-1 rule is a common hospital timing guide.
Ask most people what a contraction feels like, and they describe a sudden, cinematic wave of intense pain. The reality of early labor is often less dramatic and far more confusing, especially during those first few hours.
When a contraction fades as soon as you stand up, or comes back fifteen minutes later, it is natural to second-guess whether labor has begun. This guide walks through exactly how to monitor them — which tools to use, which rules of thumb apply to first babies versus subsequent births, and when the pattern suggests you should contact your provider.
Tracking The Essential Three: Frequency, Duration, And Intensity
Reliable monitoring starts with three specific metrics: how often contractions come, how long each one lasts, and how strong they feel to you.
Frequency measures the time between contractions. Start your timer at the beginning of one contraction and stop it at the beginning of the next. This gives you the interval, which typically shortens as labor progresses.
Duration measures the length of a single contraction. Press start when the uterine tightening is first noticeable and stop when the muscle fully releases. Many first-time labors begin with contractions that last 30 to 45 seconds.
Intensity is more subjective but still useful. Track whether you can talk or walk through the contraction. If you cannot speak a full sentence during a contraction, it is a sign that labor may be active, and that information is valuable for your care team.
Why The Rules Of Thumb Change For Your Situation
Whether this is your first baby or your fourth makes a noticeable difference in how you should respond. Your care team expects different patterns depending on your birth history.
- First baby: Head for the delivery unit when contractions feel strong, last 45 to 60 seconds each, and occur every 3 to 4 minutes for at least 2 hours.
- Second or later baby: Move toward the hospital when contractions come every 5 minutes for at least 1 hour. Labors often progress faster after the first birth.
- The 411 rule: Some providers recommend going in when contractions are 4 minutes apart, lasting at least 1 minute. This pattern can signal that labor is about to pick up speed.
- Irregular contractions: If intervals vary widely — for example, 5 minutes, then 8 minutes, then 6 minutes — you likely still have time before active labor fully begins.
The key is to look at the overall trend over an hour or two, not to react to a single close contraction. A consistent pattern is more meaningful than a single number.
How To Use The 5-1-1 Rule With A Labor Log
The 5-1-1 rule is one tool for assessing the difference between warm-up (Braxton Hicks) contractions and actual labor contractions. A common interpretation suggests heading to the hospital when contractions are 5 minutes apart, lasting 1 minute each, for at least 1 hour.
Cleveland Clinic explains that timing from the start of one contraction to the start of the next is the standard way To Monitor Contractions. Keeping a written labor log helps you see whether your pattern is strengthening or staying random. Walking or moving around can also help distinguish true labor from Braxton Hicks, since false contractions often stop with activity.
A simple hand-written log is often more reliable than memory. Write down the start time, end time, and a quick note on intensity for each contraction over at least one hour.
Braxton Hicks Versus True Labor
| Feature | Braxton Hicks (Warm-up) | True Labor Contractions |
|---|---|---|
| Duration | Irregular, vary widely | Gradually longer and more consistent |
| Frequency | No pattern, may stop | Regular intervals, shorten over time |
| Intensity | Mild, usually stays the same | Grows stronger with each wave |
| Effect of Movement | Often stops with walking | Intensifies or continues |
| Location of Sensation | Usually front or groin | Starts in back, wraps to front |
Watching how contractions behave across these categories over an hour gives you a clearer picture than focusing on any single feature.
Tools That Can Support Your Monitoring Routine
You do not need high-tech equipment to monitor contractions at home, though some digital tools can simplify the process.
- Stopwatch or phone timer: The most straightforward method. Press start at the beginning of a contraction and stop at the end. Repeat for the next contraction to measure the interval.
- Contraction tracking apps: Free apps can automatically calculate averages, log the pattern over time, and generate a summary to share with your provider.
- Paper and pen: A simple written log is very reliable. Draw three columns — start time, end time, and intensity — and fill them in as labor progresses.
- A partner or support person: They can keep track of the clock and the log while you focus on breathing and staying comfortable through each wave.
Pick one method early in labor and stick with it for at least an hour. Switching methods mid-stream makes it harder to spot a reliable trend in your data.
What The Hospital Monitor Tells Your Care Team
When you arrive at the hospital, your care team places a fetal monitor that uses a tocodynamometer (TOCO) to measure contraction pressure. This device gives them a numerical view of your uterine activity.
One source on Tocodynamometer Contraction Measurement suggests that Braxton Hicks typically register 5 to 25 mmHg on a TOCO monitor, while active labor contractions range from 40 to 60 mmHg. Second-stage pushing contractions may reach 50 to 80 mmHg. These ranges are approximate, and your experience may differ.
The monitor helps the medical team assess whether labor is progressing normally and how the baby is responding to each contraction. This information is combined with your cervical exam and the baby’s heart rate pattern for a full picture.
Contraction Progression at a Glance
| Phase | Typical TOCO Range (mmHg) | What You May Feel |
|---|---|---|
| Warm-up (Braxton Hicks) | 5–25 | Tightening, irregular, no rhythm |
| Active Labor | 40–60 | Strong, cannot talk through |
| Second Stage (Pushing) | 50–80 | Intense urge to push |
These numbers are reference points. Your care team interprets them alongside your individual history and the baby’s status.
The Bottom Line
The goal of monitoring at home is to recognize a strengthening and regular pattern. Use the 5-1-1 rule or the 411 rule as a general guide, but pair them with a written log and pay attention to intensity changes over at least an hour.
If your water breaks, you have heavy bleeding, or you feel decreased fetal movement, call your obstetrician or go to the delivery unit immediately — even if your contractions are still irregular or widely spaced.
