Contraction Timer Guide: How to Time Contractions

It is two in the morning. You feel a tightening in your abdomen and think: was that a contraction? Or just practice? And should you wake your partner and head to the hospital, or is it too early?

Babysential's contraction timer helps you keep a clear head. You tap a button, and the tool does the rest — measuring duration, calculating intervals, and telling you when the pattern suggests labor has begun.

Why Time Contractions?

Midwives and obstetricians use the contraction pattern to assess how far along labor has progressed. They need to know three things:

• How long does each contraction last? Active contractions typically last 45–60 seconds
• How often do they come? Measured from start to start
• How regular are they? Irregular contractions suggest an early phase

Without timing, many people end up going to the hospital too early — and getting sent back home. Or they wait too long because they underestimated the pattern.

How to Use the Contraction Timer

Step 1: Open the Timer

Go to the contraction timer when you feel the first tightenings. You do not need to log in to use it — the tool works immediately.

The contraction timer is designed to be easy to use even in the middle of the night, with large buttons and clear text.

Step 2: Tap Start With Each Contraction

When you feel a contraction beginning, tap the large button. Tap again when it releases. The timer records:

• Duration — how many seconds the contraction lasted
• Interval — time since the previous contraction started
• Timestamp — exact time of each contraction

Step 3: Mark Pain Level

After each contraction, you can mark your pain level on a scale from 1 to 5. This gives you and your care team valuable additional information. Increasing pain levels over time are a sign that labor is progressing.

Step 4: Read the Pattern

The contraction timer automatically calculates:

• Average duration of recent contractions
• Average interval between contractions
• Trend — are contractions getting closer together and longer?

The graph displays the progression visually. You can see at a glance whether the pattern is changing.

Step 5: Share With Your Partner or Care Provider

Export the contraction log as an image or text. Perfect for sending to your midwife or doctor by phone, or so your partner can follow along when you are focused on breathing.

Contractions or Braxton Hicks?

Many pregnant people experience Braxton Hicks contractions (practice contractions) from week 20 onward. They can feel quite strong, but they are not "real" contractions. Here is the difference:

Braxton Hicks:

• Irregular and unpredictable
• Disappear when you change position or rest
• Felt mostly in the front of the abdomen
• Do not get stronger over time

Real contractions:

• Gradually become more regular
• Do not disappear with a change of position
• Radiate from the back and around the abdomen
• Increase in strength and duration

The contraction timer helps you see the difference. An irregular pattern with no trend? Probably Braxton Hicks. Getting consistently closer and stronger? Call your maternity unit.

When Should You Call the Hospital?

Beyond the 5-1-1 rule, always call your maternity unit if:

• Your water breaks (regardless of contraction pattern)
• You have bleeding
• The baby is moving less than usual
• You feel something is wrong

The contraction timer flags warning signs with clear alerts. Trust your gut — it is better to call once too many times than once too few.

Frequently Asked Questions

Can I Use the Contraction Timer Without Internet?

The contraction timer saves data locally on your device. You can time contractions even without an internet connection. The log syncs when you are back online.

Should My Partner Time Contractions for Me?

Absolutely! Many people in labor prefer to focus on breathing while their partner handles the timing. Hand your partner the phone and show them how the large buttons work — it takes seconds to learn.

What Do I Do With the Contraction Log Afterward?

Many people find it meaningful to keep the contraction log as part of their birth story. You can export it and save it alongside other memories from your baby's birth day.

Prepare Before It Starts

Load the contraction timer on your phone a few weeks before your due date. Add it as a shortcut on your home screen. That way you will not be searching for it in the middle of a contraction at three in the morning.
