Knowing exactly when to leave for the hospital is one of the biggest worries near the end of pregnancy — go too early and you may be sent home, too late and it feels frantic. The good news: there are clear signs to watch for, and your maternity unit is always a phone call away.
When should I go to the hospital in labor?
For a first baby, the most common guide is the 5-1-1 rule:
- 5 — contractions are about 5 minutes apart (from the start of one to the start of the next)
- 1 — each contraction lasts around 1 minute
- 1 — this pattern has kept up for at least 1 hour
When all three are true, it is usually time to head in (or call ahead first). Some providers use a slightly different version — 4-1-1 (4 minutes apart) or 3-1-1 (3 minutes apart) — especially if this isn’t your first baby, if your labors tend to be quick, or if you live far from the hospital. Always follow the exact rule your own provider gave you; the numbers below are just the common starting point.
| Rule | Contractions apart | Each lasts | For at least | Often used for |
|---|---|---|---|---|
| 5-1-1 | 5 minutes | ~1 minute | 1 hour | A first baby |
| 4-1-1 | 4 minutes | ~1 minute | 1 hour | Later baby / longer drive |
| 3-1-1 | 3 minutes | ~1 minute | 1 hour | Fast labors / far from hospital |
A simple way to track the pattern is to time your contractions — our contraction timer records how far apart they are and how long each one lasts, so you can see when you hit your rule without doing the maths in the middle of a contraction.
How do I tell real labor from false labor?
In the weeks before birth, many people feel Braxton Hicks (practice) contractions. The pattern is the clearest clue:
- Real labor: contractions get longer, stronger and closer together over time, and keep going whether you walk, rest or change position.
- False labor: contractions are irregular, don’t build up, and often ease off when you move around, rest or drink some water.
If timing them for an hour shows a steady, tightening rhythm, that points to real labor. If they stay scattered and fade, it is likely practice — though you can always call to check.
When should I go in or call right away — whatever the timing?
Some signs mean you shouldn’t wait for any contraction rule. Go to the hospital, or call your maternity unit immediately, at any hour, if:
- Your waters break — note the time and the colour of the fluid. Clear or pale is usual; green or brown fluid, or a sudden gush, needs prompt care, so call straight away.
- You have any vaginal bleeding (more than a little blood-streaked mucus).
- Your baby is moving less, or differently, than usual.
- You have severe, constant pain that doesn’t come and go like a contraction.
- You are under 37 weeks and think labor may be starting (this could be preterm labor).
You should also call if your contractions are very intense and close together early on, if you feel a strong urge to push, or if anything simply feels wrong. Trust your instinct — calling is always the right move.
What should I do before I leave?
A little prep makes the trip calmer:
- Call ahead. Let your maternity unit or labor ward know you’re coming so they’re ready for you.
- Bring your hospital bag. If it isn’t packed yet, our hospital bag checklist covers what you and baby will need.
- Note the key details to share on the phone: when contractions started, how far apart and how long they are now, and whether your waters have broken (and the fluid colour).
- Plan the journey — who’s driving, and a backup if they’re unavailable.
What if it’s the middle of the night, or I’m just not sure?
Then you call anyway. Maternity units are staffed around the clock and expect these calls — at 2 a.m. just as much as 2 p.m. They would far rather you ring with a question than sit at home worried, and they can help you decide whether to come in, keep timing, or rest a little longer.
There is no such thing as bothering them, no silly question, and no wrong hour. If you’re unsure whether it’s time, that uncertainty is itself a good reason to pick up the phone.
When you’re getting close, timing a few contractions with the contraction timer gives you the exact numbers to read out — which makes that call quicker and easier for both of you.
