How to Know If You're in Labor: A Guide for New Dads

Your partner’s uterus is about to become the hardest-working muscle in the house. No pressure. Well, quite a lot of pressure, actually.

Labor rarely kicks the door in. It sneaks in. It starts, it stops, it picks up again in the middle of the night, and you both keep asking the same question: is this it? Here’s how to read the signs, time contractions and know when to call.

How do you know if you’re in labor?

You’re probably in labor when contractions keep coming whatever she does, and get longer, stronger and closer together over a few hours. Practice contractions stay irregular and fade when she rests.

The biggest tell isn’t on the timer, though. It’s her. When she can’t be distracted anymore, stops talking or walking during a contraction and goes somewhere inside herself for a minute, you’re probably into the real deal.

What is a contraction?

A contraction is her uterus tightening and then letting go. Every one does two jobs: it nudges the baby down, and it works on the cervix, the little doorway at the bottom of the uterus. First the cervix gets softer and thinner, then it starts to open. Ten centimeters is the magic number.

Signs labor is coming soon

In the days or weeks before labor, her body starts getting ready. You might notice:

A low backache that won’t go away, or cramps like period pain
Loose bowel movements
A sudden urge to clean and organize, called nesting
The baby sitting lower in her belly, called dropping
Losing the mucus plug: a blob of mucus, sometimes pink or streaked with blood. Normal.

None of these mean you need to call anyone. They do mean it’s a good week to cancel the out-of-town trip.

Braxton Hicks vs real contractions: how to tell the difference

Practice contractions, or Braxton Hicks, are irregular, don’t build, and often ease off when she rests, drinks water or changes position. Real contractions keep coming and get longer, stronger and closer together, whatever she does.

	Practice	Real labor
Pattern	Irregular	Regular, closer together
Strength	Stays about the same	Gets stronger
When she rests	Eases off or stops	Keeps coming
Can she talk through one?	Usually	Not really

Some rounds of practice contractions are strong and go on for hours, then just fade. Annoying, and completely normal. If you’re not sure, try a glass of water, some rest and a change of position, then see what the next hour brings.

How to time contractions

Time contractions from the start of one to the start of the next. That’s how far apart they are. How long each one lasts is from its start to its end.

The easiest way is our free contraction timer. She says “now”, you tap. She says “done”, you tap again. It does the math and tells you when you’ve hit 5-1-1.

You don’t have to time every single one. You’ll both go mad. Time five or six in a row, look at the pattern, then put the phone down. Make her a sandwich. Put on a show. When the contractions clearly feel stronger to her, time another five or six.

When to go to the hospital for contractions: the 5-1-1 rule

Most US hospitals use the 5-1-1 rule: call when contractions are about 5 minutes apart, about 1 minute long, for at least 1 hour. If your doctor or midwife gave you a different rule, theirs wins.

The 5-1-1 rule

5minutes apartFrom the start of one to the start of the next.
1minute longEach contraction lasts about a minute.
1hour of thisThe pattern holds for at least an hour.

Hit all three? Call your doctor or the hospital.

Before that point comes early labor, the slow part. The contractions are real but still manageable, and this stretch can go on for hours, sometimes a lot of hours, especially with a first baby. For a healthy pregnancy, it’s usually easier at home: her own couch, her own snacks, no fluorescent lights. ACOG notes that being admitted very early in labor is linked to more interventions later on. Your job in early labor is to keep her eating, drinking and resting, and to time contractions now and then.

And yes, that hour can feel long. If she’s struggling or you’re unsure, call anyway. Some doctors want a call sooner, for example if you live far from the hospital or it isn’t her first baby, so ask your OB or midwife before the due date.

How to tell if her water broke

Her water breaking can be a gush or a leak. A gush is a sudden rush of fluid she can’t stop, sometimes with a pop. You’ll know. A leak is a trickle that keeps coming back when she stands up or moves. Either way, call your doctor or the hospital, even if there are no contractions yet.

In the movies, it’s a dramatic gush in a supermarket aisle. In real life, it usually happens once labor is well underway, often at the hospital. Only about 1 in 10 labors start with the water breaking.

How to tell if your water broke or you peed

Unlike pee, she can’t hold it in, and it keeps coming back. That can leave you both wondering whether it was her water or her bladder formally resigning. A leak is the tricky one, because it’s easy to shrug off, so couples wait. Don’t. Call and let them decide.

What to check before you call: TACO

The nurse on the phone will likely ask about these four things, so remember one word: TACO.

RememberTACOWhat the nurse will ask

TimeWhen did it happen? Write it down.
AmountA gush or a leak?
ColorIt should be clear. Green, brown or red? Say so.
OdorIt should smell like almost nothing.

One small job for before week 36: find out where the pads are and put some in her hospital bag. Pads, not tampons.

When not to wait for 5-1-1

Some signs skip the timing game completely. Call your doctor or the hospital right away if:

Her water breaks, or you think it did
The fluid is green, brown, bloody or smells bad
There’s heavy bleeding, more than a period
The baby is moving less than usual
She’s under 37 weeks and it might be labor
She has severe pain that doesn’t ease between contractions
She has a fever, a severe headache or changes in her vision
She feels a strong urge to push
Your doctor told you to come in sooner
Either of you feels something is wrong

If it feels like an emergency, call 911. When in doubt, call.

What are the stages of labor?

Labor moves through early labor, active labor, transition, pushing and birth, and finally the placenta. Here’s what each looks like, and your move in each one.

The stages of labor, and your move

Hours, sometimes daysEarly labor
Contractions keep coming and slowly build, but she can still talk between them. Your move: stay home, keep her fed and rested, time now and then.
Several hoursActive labor
Longer, stronger, closer. This is roughly your 5-1-1 moment, and usually when you go in. Your move: call, go, then offer water and press on her lower back if she wants it.
The hardest bitTransition
The last and most intense stretch before pushing. She might shake, feel sick, cry or say she can’t do it. It usually means she’s close. Your move: “You’re doing it.” “One at a time.” “Almost there.”
Minutes to a few hoursPushing and birth
She’s fully open and feels a strong urge to push. Your move: stay by her head, keep encouraging her and follow the team’s lead.
Within about 30 minutesThe placenta
Just when you think it’s over, there’s one more delivery. Your move: meet your kid, and don’t be surprised the team is still busy with her.

How long does labor last?

For a first baby, labor usually takes 8 to 18 hours once it’s properly established, and the early part before that can take much longer. The rough timing of each stage is in the timeline above.

Every labor is different, and your baby hasn’t checked the schedule. And if the team decides to get things going for you, here’s what to expect when being induced.

Through all of it, you don’t run the show. You keep her company and keep the room calm. For the hands-on part once you’re there, read the dad’s role in the delivery room, and keep the free cheat sheet on your phone for the day itself.
