The 5-1-1 rule: when to call or go to the hospital
Short answer: 5-1-1 means contractions about 5 minutes apart, each lasting about 1 minute, for at least 1 hour. Many hospitals and midwives use it as the point to call them or head in — but the rule you were given always wins.
1. How to time it
Note when each contraction starts and when it ends. Length is start to end. Time apart is start to the next start. One contraction tells you little; the pattern over the last hour is what matters.
Example: contractions start at 6:00, 6:05, 6:11, 6:16 and so on, each lasting 55–65 seconds, for an hour. That is roughly 5-1-1.
2. 4-1-1 and 3-1-1
Some care teams ask you to wait for 4-1-1 or 3-1-1, others to call earlier. Distance to the hospital, a previous fast labor, or a medical reason can change the advice. Write your rule down before the day.
3. Call now, whatever the clock says
- Your water breaks or you leak fluid
- Bleeding
- Your baby moves less than usual
- Constant, severe pain or pain between contractions
- Fever, headache or vision changes
- Anything that feels wrong to you
How Arrivelle helps
Tap once when a contraction starts and once when it ends. Arrivelle shows the last-hour average time apart, average length and count, and you pick 5-1-1, 4-1-1 or 3-1-1. When the last hour gets close, a small card suggests calling — it never takes over the screen. Missed a tap? Add it afterwards.
This guide is general information, not medical advice. When to call or go in is decided with your hospital or midwife — and if something feels wrong, contact them right away.
FAQ
Is 5-1-1 the same for everyone?
No. Many care teams use 5-1-1 for a first baby. Some suggest 4-1-1 or 3-1-1, or calling earlier if you live far away, had a fast labor before, or have a medical reason. Use the rule you were given.
Do I measure from the start or the end of a contraction?
Time apart is measured from the start of one contraction to the start of the next. Length is from start to end of the same contraction.
What if my contractions are irregular?
Irregular contractions that do not get closer or stronger are common before labor. Keep timing for a while, rest, and call your care team if you are unsure.
