Early labor is the first and longest phase of labor, spanning from when regular contractions begin until your cervix dilates to about 6 centimeters. During this stretch, contractions gradually become stronger and more predictable, your cervix thins out, and your body shifts into the work of delivering your baby. For most people, this is the phase you spend at home, and knowing what to expect can make it far less stressful.
How Early Labor Is Defined
Clinically, early labor is called the “latent phase” of the first stage of labor. It starts when you begin having regular contractions that cause your cervix to change and ends when your cervix reaches about 6 centimeters of dilation. That 6-centimeter threshold is a relatively recent update. For decades, the shift to active labor was thought to happen around 4 centimeters, but more recent data showed that many women don’t truly enter active labor until 5 to 6 centimeters. The American College of Obstetricians and Gynecologists (ACOG) now uses 6 centimeters as the official start of active labor. This change has practical significance: it means more time is considered “normal” before medical intervention is warranted, which has helped reduce unnecessary cesarean deliveries.
What Early Labor Contractions Feel Like
Early labor contractions often start as a dull ache in your lower back or a tightening sensation across your abdomen. At first, they may feel similar to menstrual cramps. What sets them apart from the practice contractions you may have had for weeks is their pattern: true early labor contractions come at regular intervals and gradually get closer together, last longer, and feel stronger over time.
In the beginning, contractions might be 15 to 20 minutes apart and last only 30 to 45 seconds. As early labor progresses, they shorten the gap between them and grow more intense. You’re generally considered ready to head to the hospital once your contractions follow the 5-1-1 rule: every 5 minutes apart, lasting 1 minute each, for at least 1 hour straight.
Early Labor vs. Braxton Hicks Contractions
One of the trickiest parts of early labor is figuring out whether it’s the real thing. Braxton Hicks contractions (often called “false labor”) can feel convincingly similar, especially in the final weeks of pregnancy. Here’s how to tell them apart:
- Pattern. True labor contractions have a rhythm and get closer together over time. Braxton Hicks contractions are irregular and don’t follow a predictable schedule.
- Response to rest. If you lie down, drink water, or change position and the contractions fade or stop, they’re likely Braxton Hicks. True labor contractions keep coming regardless of what you do.
- Intensity. True contractions get progressively stronger. False contractions tend to stay at the same level or even weaken.
Sometimes the only way to know for sure is a vaginal exam to check whether your cervix is actually changing. If you’re uncertain, timing your contractions for an hour while resting and drinking water is a reliable first step.
Other Physical Signs
Contractions aren’t always the first signal. Several other changes can indicate your body is entering early labor or getting very close to it.
The mucus plug, a thick barrier that seals the opening of your cervix throughout pregnancy, may come loose as your cervix begins to thin and open. When it’s tinged with blood, it’s called “bloody show.” This discharge looks like jelly-like, stringy mucus that can be red, pink, or brown. The total amount is usually small, no more than a tablespoon or two. Losing your mucus plug can happen days before labor or right as it starts, so on its own it’s not a reason to rush anywhere, but it does mean things are moving in the right direction.
Your water breaking (the rupture of the amniotic sac) can also happen during early labor, though it occurs before contractions start in only about 10 to 15 percent of pregnancies. It might be a dramatic gush or a slow, steady trickle that’s easy to mistake for urine. If your water breaks, note the time and what the fluid looks like, because your care provider will want to know.
How Long Early Labor Lasts
This is the part with the widest range, and the least satisfying answer: early labor can last anywhere from a few hours to well over a day. It tends to be significantly longer for first-time mothers. If you’ve given birth before, your cervix has already done this work once, and the latent phase is often shorter the second time around.
The unpredictability is normal. Labor can start and stall, pick up and slow down. Some people have mild contractions for an entire day before things ramp up, while others move from first contraction to active labor in just a few hours. Neither pattern is a cause for concern as long as you and the baby are doing well.
Managing Early Labor at Home
Because early labor is typically the longest phase and the least medically urgent, most providers encourage you to spend it at home where you’re comfortable. Current guidelines support this approach as long as both you and the baby are in reassuring condition. Arriving at the hospital too early can lead to interventions that may not be necessary yet.
What actually helps during this phase is straightforward. Rest when you can, especially if labor starts at night. Eat light meals and drink plenty of water, since you’ll need the energy later. Gentle movement like walking or swaying can help you cope with contractions and may encourage labor to progress. A warm shower or bath can ease back pain. Breathing slowly through contractions is more effective than tensing up against them.
Keep a log of your contractions, noting when each one starts, how long it lasts, and the gap between them. Several smartphone apps can do this for you. Watching the pattern develop gives you useful information for when you call your provider, and it can also be reassuring to see that things are progressing in a clear direction.
Signs to Go to the Hospital
The 5-1-1 rule (contractions every 5 minutes, lasting 1 minute, for 1 hour) is the most widely used benchmark for calling your provider or heading in. But certain situations call for immediate attention regardless of your contraction pattern: if your water breaks, if you notice significant vaginal bleeding (more than the small amount of bloody show), or if you feel a strong urge to push. Decreased fetal movement, severe headache, or vision changes also warrant a call right away.
Your provider may give you personalized instructions based on your pregnancy history, how far you live from the hospital, or specific risk factors. If they’ve told you to come in earlier than the 5-1-1 rule, follow their guidance over any general rule of thumb.
