Most first-time parents head to the hospital too early. The 5-1-1 contractions rule takes the guesswork out of it. Here's exactly when it's time to go.
The 5-1-1 Rule, in One Paragraph
The 5-1-1 rule says: head to the hospital when your contractions are 5 minutes apart, last 1 minute each, and have followed that pattern for at least 1 hour. It is a common rule of thumb for low-risk, full-term first labors, and your OB or midwife may give you a different one, especially if this is not your first baby (see First Baby or Second). Some warning signs, water breaking with green fluid, heavy bleeding, decreased fetal movement, or contractions before 37 weeks, override the rule entirely; call your provider or head in immediately. Use a tool like our Contraction Timer to measure intervals and duration without doing the math while in labor.
What Is the 5-1-1 Rule?
The 5-1-1 rule is a simple guideline that midwives and OBs recommend. It tells you to head to the hospital when your contractions follow this pattern:
- 5 minutes apart, measured from the start of one contraction to the start of the next
- 1 minute long, each contraction lasts about one minute
- 1 hour of this pattern, the pattern has been consistent for at least one hour
When all three criteria are met, you're likely in active labor. It's time to call your birth team and get ready to go.
Some hospitals use the 4-1-1 rule instead (4 minutes apart). Check with your care provider or birth center to find out what they recommend.
How to Track Contractions Correctly
To use the 5-1-1 rule, you need accurate measurements. Here's what to track:
Interval: Start timing when a contraction begins. Stop when the next one begins. That's your interval.
Duration: Start timing when a contraction begins. Stop when it fully releases. That's the duration.
Pattern: Write down the times. After 4–5 contractions you'll be able to see if there's a pattern.
You can use pen and paper, but it's much easier with a tool that does the tracking for you. A free contraction timer app will measure intervals, duration, and pattern automatically, and can alert you when contractions hit the 5-1-1 pattern.
When Should You Call Your Provider?
Call your midwife, OB, or labor and delivery unit when:
- Contractions follow the 5-1-1 pattern
- You're unsure whether you're having "real" contractions
- Your water breaks
- You need guidance or reassurance
The person on the phone will ask about the frequency, duration, and intensity of your contractions. Have your timer in front of you so you can give precise answers.
It's always okay to call. Your care team would rather hear from you one time too many than one time too few.

First Baby or Second: When to Go
The 5-1-1 rule is usually described for a first labor. If you have given birth before, two things change the picture.
Later labors are usually shorter. ACOG says labor with a first baby typically lasts 12 to 18 hours, and 8 to 10 hours for someone who has given birth before. It adds that every labor is different, and yours may even differ from one child to the next.
The NHS describes the same pattern. From the start of established labor to full dilation usually takes 8 to 18 hours in a first pregnancy, and is often quicker, around 5 to 12 hours, in a second or third.
When to call is something to settle before labor starts. The NHS says to call your midwife or maternity unit if you think you're in labor, or once your contractions are regular and coming every 5 minutes or more often. Neither the NHS nor ACOG sets a separate contraction rule for a second baby in its patient guidance.
ACOG's advice is to talk with your health care team well before your due date about the right time to call, and whether to call first or go straight to the hospital. It also suggests working out how long the drive takes once you count traffic. A shorter labor plus a long drive is the combination to raise.
Some OBs, midwives and hospitals give second-time parents a different threshold, such as 4-1-1 (contractions 4 minutes apart) or 3-1-1. These are local rules, not ones ACOG or the NHS publish, so ask yours which one applies to you.
If contractions keep starting and stopping without settling into a regular pattern, read about prodromal labor, and call if you're unsure. If a previous labor was very fast, or you live far from the hospital, read precipitous labor: signs of a fast labor and when to leave and bring it to your next appointment.
In Wave: open This labor and set Experience to "Second or later". Wave keeps watching for the 5-1-1 pattern, and in this mode it can also show an earlier heads-up suggesting you consider calling your provider.
The heads-up appears when at least 6 contractions in the past hour average 7 minutes apart or less and you rated the latest one Strong (3 of 5) or higher. If the latest contraction has no rating, it does not appear, and it only shows before 5-1-1 is reached. It is not a 4-1-1 detector, and it does not replace the rule your provider gave you.
Warning Signs: Go to the Hospital Immediately
Some situations require you to go to the hospital right away, regardless of your contraction pattern:
- Water breaking with green or brown fluid, may indicate meconium
- Heavy bleeding, more than a normal period
- Decreased fetal movement, baby is moving less than usual
- Intense, continuous pain, no pause between contractions
- You're before 37 weeks, this is considered preterm labor
- You feel something is wrong, trust your gut
If your water breaks, always contact your care provider even if contractions haven't started yet. Note the color, smell, and time it happened.

What to Do While You Wait
The time between your first contractions and leaving for the hospital can be long, especially for first-time parents. Here's how to stay comfortable:
- Move around, walk, sway your hips, sit on a birth ball
- Rest between contractions, save your energy
- Eat lightly, fruit, yogurt, or toast will give you fuel
- Stay hydrated, dehydration can make contractions irregular
- Practice breathing, slow, deep breaths help manage pain
- Check your hospital bag, is everything packed?
Tips for the Ride to the Hospital
When it's time to go:
- Know your route, do a practice drive so you know the way
- Bring pillows, sit comfortably in the back seat
- Have a towel handy, in case your water breaks in the car
- Avoid rush hour, leave with plenty of time if possible
- Call ahead, let labor and delivery know you're on your way
Frequently Asked Questions
Can contractions stop after they've started?
Yes. Many people experience contractions that start and stop, especially early in labor. This is completely normal and is sometimes called "false labor" or prodromal labor. Move around, rest, and wait for the pattern to become steady and predictable.
How do I tell the difference between Braxton Hicks and real contractions?
Braxton Hicks contractions are irregular, go away when you change position, and are mostly felt at the front of the belly. Real contractions come at regular intervals, get stronger and more frequent over time, and are often felt in the lower back as well. Use a contraction timer to see the pattern clearly.
Should my partner call the hospital for me?
It can be a good idea. During intense contractions it can be hard to talk. Your partner can relay the information from your contraction timer to your care team. Go over what to say beforehand.

Helpful tools
- Contraction Timer (Wave). Automatically detects the 5-1-1 pattern. In "Second or later" mode it can also show an earlier heads-up, before 5-1-1, when your recent contractions average 7 minutes apart or less and you rated the latest one Strong or higher. It is not a 4-1-1 detector. No math while in labor.
- Birth Plan Builder (Bloom). Build a printable birth plan to bring to the hospital alongside your hospital bag.
- Pregnancy Journal. Log late-pregnancy symptoms so anything unusual (decreased fetal movement, leaking fluid) is easy to flag with your provider.
- Hospital Bag & Newborn Checklists. Make sure your bag is packed before contractions start in earnest.
