When to go to the hospital checker

Use this free checker to compare your recent contractions with the timing rule in your birth plan. It can organize interval, duration, and consistency, but it cannot diagnose labor or decide whether traveling is safe.

When should you go to the hospital?

Go when your maternity care team tells you to go, when your personalized timing threshold is met, or when you are worried about a symptom or change. Do not wait for a checker result if your clinician has already given you different instructions.

The checker reviews the contractions you record and compares their recent interval, duration, and consistency with the rule you select. A matching result means it is time to follow your care plan, usually by calling your hospital, birth center, midwife, or obstetric team before leaving.

A nonmatching result does not prove that you are not in labor. Contractions can change quickly, and labor duration varies substantially between people and between first and later births (Tilden et al., 2022; Merck Manual, 2025).

How to use the checker during contractions

Start by selecting the timing rule your clinician gave you. If your instructions do not match the available presets, use your written plan rather than choosing the closest rule.

1. Start timing at the beginning of a contraction.
2. Stop when the contraction ends.
3. Repeat without intentionally skipping contractions.
4. Review the recent pattern, not just the strongest or longest contraction.
5. Call your care team when the pattern reaches your instructions or when you are unsure.

Interval means the time from the start of one contraction to the start of the next. Duration means how long an individual contraction lasts, while pattern span describes how long the repeating pattern has continued.

If timing on the web becomes awkward, Contraction Timer IO also provides a free timer for iPhone, Apple Watch, and Android. A birth partner can handle timing so the laboring person can focus on comfort and communication.

Glance check: recent timing, 5-1-1, and 4-1-1

Use this table to understand what the checker is comparing. The named rules are general shorthand, not universal admission policies.

Why your recent pattern matters more than one contraction

One long, painful, or closely spaced contraction does not establish a repeating pattern. The checker looks at a sequence so you can see whether intervals are becoming steadier, durations are changing, and the pattern is continuing.

Early labor can be lengthy. Research has found substantial differences in latent and active labor duration, including differences between people giving birth for the first time and those who have given birth before (Tilden et al., 2019; Tilden et al., 2022).

Record contractions as accurately as you reasonably can, but do not delay a call to collect cleaner data. If contractions are difficult to time, the pattern suddenly changes, or you cannot comfortably monitor the situation, contact your maternity unit and describe what is happening.

Call your care team instead of waiting for the timer

Contact your hospital, birth center, midwife, or obstetric team if you think your water has broken, have bleeding that concerns you, feel pressure or an urge to push, have severe or unusual symptoms, or simply believe something is wrong. The checker cannot evaluate fluid, bleeding, pain, blood pressure, fetal position, cervical change, or how quickly labor may progress.

Call promptly if your baby's movements are reduced or the usual pattern has changed. NHS guidance emphasizes the baby's normal daily pattern rather than a universal movement count and advises urgent contact when movement decreases or changes (NHS, 2020).

Use emergency services when you believe there is an immediate emergency or cannot safely reach maternity care. Follow any urgent instructions already provided by your clinical team.

What this hospital checker cannot decide

This tool is not medical advice, a diagnosis, or a substitute for speaking with a qualified maternity professional. It cannot confirm true labor, measure cervical dilation, predict birth time, or guarantee that remaining at home is safe.

Its output depends entirely on the entries and rule selected. Missed contractions, late taps, movement between devices, or another person timing by observation can make the displayed pattern less accurate.

Your clinician may recommend earlier assessment because of your medical history, previous labor, distance from the hospital, planned cesarean birth, multiple pregnancy, pregnancy complications, or other individual factors. I do not have a sourced universal travel-time adjustment or hospital admission threshold.

Save your maternity unit's phone number and instructions where both you and your birth partner can find them. Treat the result as a prompt to follow that plan, not as permission to ignore symptoms or professional advice.
