# The 5-1-1 Rule: When to Go to the Hospital During Labor _What 5-1-1 means, when it applies, and the other signs that say "go now."_ - Source: https://proba.baby/en/blog/5-1-1-rule - Published: 2026-09-05 - Author: ProbaBaby Team - Category: Pregnancy - Tags: labor, safety - Language: English > The 5-1-1 rule is shorthand: contractions 5 minutes apart, 1 minute long, for 1 hour. But it's a starting point, not the only signal. Here's how to read your contractions, what your provider really needs to know when you call, and the cases where you don't wait for 5-1-1 at all. > **Medical disclaimer.** This article is general information about labor and is not a substitute for medical advice. Your provider may give you different specific guidance based on your pregnancy and history — follow their instructions over anything you read online. If you have severe symptoms (heavy bleeding, decreased fetal movement, severe pain), call your provider or go to the hospital regardless of the 5-1-1 rule. If this is your first pregnancy, you've probably been told "go to the hospital when you're 5-1-1." It rolls off the tongue and it's mostly correct — but it leaves out a lot. Here's the full picture. ## What 5-1-1 means **5-1-1 stands for:** - Contractions about **5 minutes apart** (measured start-to-start, not end-to-start) - Each contraction lasting about **1 minute** - A pattern that's been consistent for at least **1 hour** When all three are true, you're typically in active labor and most US hospitals will admit you. Before that, you may be in early labor (latent phase), which can last hours or sometimes days, and your provider will usually tell you to stay home. → Use our [free contraction timer](/tools/contraction-timer) to track your contractions and get a 5-1-1 alert automatically. ## How to count correctly The single most common mistake: measuring **end-to-start** instead of **start-to-start**. - **End-to-start** (incorrect): contraction ends, then 4 minutes later the next one starts. People often round this to "5 minutes apart." - **Start-to-start** (correct): contraction starts, 5 minutes later the next one starts. If each contraction is 1 minute long, the difference is small. If contractions are 90 seconds long, the difference is meaningful. Always use start-to-start. Every contraction timer worth using (including ours) tracks it that way. ## Why does 5-1-1 work? Hospitals don't want to admit you in early labor because: 1. You'll be more comfortable laboring at home. 2. Hospital admission can slow labor down (stress, unfamiliar environment, frequent monitoring). 3. The longer you're admitted, the more medical interventions tend to happen. 5-1-1 is a reasonable proxy for "active labor has started and is progressing." If contractions are happening every 5 minutes for a full hour, your cervix is almost certainly dilating actively. ## The 5-1-1 rule is a default. Not a law. Different providers and hospitals use different thresholds: - **5-1-1** — the most common default for first-time moms in the US - **4-1-1** — used by some providers, especially if you live close to the hospital - **3-1-1** — sometimes used for moms with previous fast labors - **First-time moms vs experienced moms** — second and subsequent babies often come faster, so providers may tell you to come in earlier **Your provider's specific guidance overrides everything else.** At your 36-week appointment, ask: "What contraction pattern do you want me to come in for?" ## When NOT to wait for 5-1-1 Go to the hospital (or call 911) immediately, regardless of contraction pattern, if you have any of these: - **Water breaks** with green, brown, or blood-tinged fluid (meconium or bleeding) - **Bright red bleeding** (not just spotting after a cervical check) - **Severe, constant abdominal pain** that doesn't go away between contractions - **Severe headache, vision changes, or upper-abdominal pain** (preeclampsia signs) - **Decreased fetal movement** — fewer than 10 kicks in 2 hours of focused counting - **You're less than 37 weeks** and having regular contractions (this could be preterm labor) - **You've had a previous fast labor** (under 4 hours) and contractions have started - **Your previous baby had a difficult delivery requiring intervention** In any of these cases, the 5-1-1 rule doesn't apply. Call your provider or go straight in. ## What your provider needs to know when you call Have these answers ready before you dial: 1. **How far apart are contractions?** (start-to-start) 2. **How long are they lasting?** (in seconds) 3. **How long have they been at this pattern?** (15 minutes? an hour?) 4. **How would you rate the pain?** (1-10; can you talk through them?) 5. **Has your water broken?** (if yes, what color, what time) 6. **Any bleeding?** 7. **When did you last feel the baby move?** 8. **What pregnancy week are you?** The first three are exactly what a contraction timer surfaces — running our timer for 20 minutes before you call gives you precise answers instead of vague ones. ## Real labor vs Braxton Hicks Braxton Hicks are practice contractions. They can start as early as the second trimester but get more frequent in the third. Here's how to tell them apart: | | Braxton Hicks | Real Labor | |---|---|---| | **Pattern** | Irregular | Regular, getting closer | | **Duration** | Stays short (15-30 sec) | Gets longer (45-90 sec) | | **Intensity** | Mild, doesn't worsen | Steadily stronger | | **Position change** | Often stops with rest, water, or movement | Continues regardless | | **Time of day** | Often evening | Anytime | | **Pain** | Tightening, mild | Sharp, can be severe | A quick test: drink a glass of water, lie on your left side, and rest for an hour. If contractions stop or become irregular, they were Braxton Hicks. If they continue or intensify, it's likely real labor. ## What about water breaking? About 10-15% of labors start with water breaking before contractions. If your water breaks: 1. **Note the time, amount, and color** of fluid. Clear is normal. Green/brown means meconium (baby passed stool in utero) and needs immediate evaluation. 2. **Call your provider.** They'll tell you when to come in. For most providers: come in within 12-24 hours even if contractions haven't started, because infection risk increases. 3. **Do NOT put anything in your vagina** (no baths, no tampons, no intercourse). Infection risk. 4. **Showers are usually fine**; check with your provider. ## When the 5-1-1 timer says go If the contraction timer's 5-1-1 alert triggers, here's the order of operations: 1. **Call your provider first.** They'll either say "come in" or "give it another hour." 2. **Don't drive yourself.** Have someone else take you. 3. **Grab the hospital bag** (which you packed [following our guide](/tools/hospital-bag-checklist), right?). 4. **Bring snacks for your partner** — you'll be on a clear liquid diet but they won't. 5. **Bring your contraction log** — show the timer history to your nurse when you arrive. ## How ProbaBaby helps The ProbaBaby iOS app's contraction timer runs as a Live Activity, so the timer is always visible on your Lock Screen and Dynamic Island — you don't have to keep waking your phone or opening the app. It also works on Apple Watch (handy when you're gripping a pillow or partner's hand with one hand). When 5-1-1 triggers, the app prompts you to call your provider, with their pre-saved number ready. If your partner or support person is also using ProbaBaby with the family-sharing feature, they get the same alerts and can see your contraction log in real time — useful when you're not in the same room.

After that, spot-check every 30-60 minutes unless something changes. **What if my contractions are 7 minutes apart but really painful?** Call your provider. Painful, regular contractions at 7+ minutes can still mean active labor, especially for second-time-plus moms. **Can the timer be wrong?** The timer can only be as accurate as your taps. If you missed the start of a contraction, the recorded duration is shorter than reality. Tap as soon as you feel the contraction begin. **Why does my contraction interval keep changing?** Early labor is often irregular. Real active labor has a more consistent pattern. If intervals are still ranging from 3 to 9 minutes after an hour of timing, you're probably still in early labor. **Should I go to L&D triage if I'm unsure?** Yes. L&D triage exists for exactly this. They'll check your cervix; if you're not yet in active labor, they'll send you home with reassurance. No one will judge you for coming in. ## Sources - ACOG: How to Tell When Labor Begins, [acog.org](https://www.acog.org/womens-health/faqs/how-to-tell-when-labor-begins) - Mayo Clinic: Signs of labor — early labor and active labor, [mayoclinic.org](https://www.mayoclinic.org/healthy-lifestyle/labor-and-delivery/in-depth/signs-of-labor/art-20046184) - NHS: Signs that labour has begun, [nhs.uk](https://www.nhs.uk/pregnancy/labour-and-birth/signs-of-labour/signs-that-labour-has-begun/) --- ProbaBaby (listed on the App Store as “Pregnancy & Baby Tracker - PB”) is a free iPhone, iPad and Apple Watch app for pregnancy, newborn and postpartum tracking, built for twins, in 32 in-app languages, with an optional AI baby-face prediction that computes Mendelian genetics (Punnett squares) from the traits you enter before any image is generated.
