How to time contractions properly

Timing your contractions properly is key for determining whether or not it’s time to head to the hospital. Many expecting parents believe that contractions are a sign that labor is about to start. The truth is that contractions are part of a long process that enables you to prepare your body for labor.

Here’s what you need to know about timing contractions.

What are contractions?

Your uterine muscles tighten and contract to help with cervix dilation before labor. The purpose of these muscle movements is also to help position your baby into the birth canal.

When do contractions typically start?

It’s common to start experiencing contractions during week 16 of your pregnancy. If it’s not your first pregnancy, you might even experience contractions earlier.

Labor contractions tend to feel more intense than the ones you experience earlier in your pregnancy. They can start a few days before labor but will typically reach their peak hours before you go into labor.

Best methods for timing contractions

The best way to time your contractions is to note what time they start. Write down the time when the contraction ends and recheck the time when the next one starts. This method helps you track the frequency and duration of your contractions.

Measure frequency and duration

There are different tools you can use:

  • Check the time on a clock or phone and use a pen and paper to keep track of contractions.
  • Get precise timing down to the second with a stopwatch or stopwatch app.
  • There are free apps for tracking contractions, like Contraction Timer or Labor Signs.
  • Keep a contraction log

Your birthing team needs as much information as possible about your labor symptoms. There is no need to time every single contraction, but a contraction log with tracking for different time intervals can be useful.

Time contractions for half an hour, take a 30-minute break, and start again to see if there are any changes in frequency or duration.

Look for patterns

Looking for patterns can help your midwife or physician determine if you’re close to going into active labor. Many expecting mothers experience a rise and fall pattern. Contractions get more frequent and intense for a while before letting up and starting again.

Here are different patterns you might notice:

  • Contractions can be regular with similar duration and frequency.
  • If frequency and duration vary, you’re experiencing irregular contractions.
  • It’s common for a progressing pattern to emerge as duration and intensity increase.
  • Non-progressing contractions can occur earlier in pregnancy. These contractions will get shorter and
  • less frequent after a while. Their purpose is to help the baby shift position.

How to time contractions properly

A common mistake is to time contractions from the end of the first one to the beginning of the next one. It’s difficult to assess when a contraction ends, and this method won’t give you an accurate count.

Don’t try to estimate the duration of your contractions without the help of a phone or watch. It’s tough to estimate how much time passes by when you’re in pain or uncomfortable.

When should you head to the hospital?

Contractions are a sign of early labor. This stage can last anywhere from eight to 12 hours. Many factors can interrupt early labor. Your contractions might stop for a period of time and begin again the next day.

During the early labor stage, your contractions will typically last from 30 to 45 seconds and happen every five to 30 minutes.

They will be mild, irregular, and will probably get stronger over time. Other symptoms like lower back pain are common during this stage, and your water might break. Keep track of your different symptoms and make sure you write down the time if your water breaks!

The purpose of contractions is to dilate the cervix. This process can take several hours. Active labor begins when cervix dilation reaches 4 to 10 cm or approximately 1.5 to 4 inches.

You’ll notice a different pattern in your contractions when active labor is about to begin. They can last as long as one minute and should happen approximately every three to four minutes. Contractions will also feel more intense.

Final thoughts

If it’s your first pregnancy, your initial instinct might be to head to the hospital when contractions start. You should wait until active labor begins. You’ll probably experience other symptoms at that time, including pressure in your lower back, sickness, and the urge to push.

Remember to check the time when a contraction starts and recheck when the next one begins. It’s time to head to the hospital when your contractions last between 45 seconds and one minute, and when they happen every three to five minutes.
