In early labor, contractions typically come every 5 to 20 minutes apart. They’re often irregular at first, with gaps that shorten gradually over hours. Each contraction usually lasts around 30 to 60 seconds, and the overall early labor phase can stretch from several hours to more than a day, especially for a first baby.
What Early Labor Contractions Feel Like
Early labor contractions feel like a tightening and releasing of the uterus. Many people describe the sensation as similar to strong menstrual cramps. The pain often starts in the back and radiates to the front of the abdomen. At this stage, contractions are mild enough that you can usually talk and move through them.
As early labor progresses, the gaps between contractions gradually shrink. You might start at 20 minutes apart, then notice them coming every 12 minutes, then every 8. This pattern isn’t always neat. Contractions can cluster together for a while, space back out, or even stop and restart hours later. That unpredictability is normal and doesn’t mean something is wrong.
Early Labor vs. Braxton Hicks Contractions
If you’re unsure whether what you’re feeling is real labor, there are a few reliable ways to tell. True labor contractions come at increasingly regular intervals and get stronger over time. Braxton Hicks contractions (false labor) tend to be weak, irregular, and don’t follow a pattern. They also don’t get closer together.
One practical test: rest, drink water, and change position. If the contractions stop, they’re likely Braxton Hicks. True labor contractions keep going regardless of what you’re doing. Another clue is location. True labor pain typically starts in the back and wraps forward, while false labor pain tends to stay in the front of the abdomen only.
What’s Happening to Your Cervix
While you’re feeling contractions, your cervix is doing two things: thinning out (called effacement) and opening (called dilation). During pregnancy, the cervix is long, firm, and closed to protect the baby. As your baby’s head presses down into the pelvis, combined with the force of contractions, the cervix softens and shortens.
Effacement is measured in percentages. At 0%, your cervix is still its full length. At 100%, it’s completely thinned out. Dilation is measured in centimeters. Early labor covers the stretch from 0 to about 6 centimeters, which is the point where active labor begins. Your cervix needs to reach 10 centimeters and 100% effacement before pushing can start. For first-time mothers, the early phase of this process is often the longest part of labor.
Other Signs That Accompany Early Contractions
Contractions aren’t the only signal. Several other changes often happen around the same time:
- Increased vaginal discharge. You may notice clear, pink, or slightly bloody discharge as the mucus plug that sealed the cervix during pregnancy moves out. This can happen days before labor or right at the start.
- The baby “dropping.” The baby’s head settles deeper into the pelvis, sometimes changing the shape of your belly. This can happen weeks or just hours before labor begins.
- Back pain. A persistent low backache that doesn’t go away with position changes often accompanies early contractions, especially when the baby is facing your abdomen.
When to Head to the Hospital
Most providers don’t want you at the hospital during early labor, when contractions are still 15 or 20 minutes apart. You’ll generally be more comfortable at home during this phase. The timing for heading in depends on whether this is your first baby.
For a first baby, the typical guideline is to come in when contractions are 3 to 5 minutes apart, each lasting 45 to 60 seconds, and this pattern has held steady for at least an hour. If you’ve given birth before, labor tends to progress faster, so most providers recommend heading in when contractions are 5 to 7 minutes apart and lasting 45 to 60 seconds.
These are general guidelines. Your provider may give you different instructions based on your pregnancy, your distance from the hospital, or specific risk factors. Regardless of contraction timing, contact your provider right away if your water breaks, you have heavy bleeding, or the baby’s movements decrease noticeably.
How Long Early Labor Lasts
There’s no reliable average for early labor. It can last a few hours or stretch across a full day or longer. People who have had a baby before tend to move through it faster because the cervix has dilated once already and typically responds more quickly to contractions. For first-time mothers, spending 12 to 18 hours in early labor is not unusual.
Early labor can also stall. Contractions might build for hours, then fade. This is frustrating but not dangerous. Rest, eat lightly, stay hydrated, and try to conserve energy. The more intense work of active labor, when contractions come every 2 to 3 minutes and last a full minute, is ahead. Early labor is a good time to practice breathing techniques, take warm showers, and let your body settle into its rhythm.
