What are the signs of labor?

True labor versus false labor

The key question is whether your contractions are the real thing. True labor contractions come in a regular pattern, grow stronger over time, move closer together, and do not ease up when you rest or drink water. They are often felt in the back or low pelvis, like strong menstrual cramps.

False labor, or Braxton Hicks, can show up for weeks beforehand. These contractions are irregular, do not get steadily stronger, and tend to fade when you change position, move around, or hydrate. A simple test: time them and see whether rest and water make them go away. If they stop, it is not true labor yet.

The 5-1-1 rule and when to go in

For a first-time labor, a widely used rule of thumb is 5-1-1: contractions about 5 minutes apart, each lasting about 1 minute, continuing for at least 1 hour. Reaching that pattern is a common signal that it is time to head to the hospital.

Treat 5-1-1 as a starting guide, not a hard rule. Some practices prefer 4-1-1 or 3-1-1, and your own provider may set a different number based on your history and distance from the hospital. If you think you are in labor or are not sure, call your provider.

Water breaking and the mucus plug

When the membranes rupture, you may feel a sudden gush or a slow trickle of fluid. Normal amniotic fluid is clear or pale yellow. Call your provider or go to your delivery facility right away, even if you are unsure whether it is amniotic fluid, and note the time it broke, the color, and the amount. The longer labor takes to start after your water breaks, the higher the infection risk, so your team will want to know.

Losing the mucus plug is another sign. The plug seals the cervix during pregnancy, and as the cervix opens you may notice increased discharge that is clear, pink, or slightly bloody, sometimes called bloody show. This can happen several days before labor or right as it begins.

Other signs and the warning signs that need a call

Some changes hint that labor is near without meaning it has started. The baby may drop lower into the pelvis (lightening), you may feel a burst of energy (nesting), or have loose stools and a dull, persistent low backache. During labor itself, the cervix thins (effacement) and opens from 0 to 10 centimeters, with 10 being fully dilated.

Certain signs need a prompt call no matter where you are in pregnancy.

Call your provider right away for any of the following.

• Any signs of labor or regular contractions before 37 weeks, which can mean preterm labor
• Vaginal bleeding, especially with contractions
• Your water breaking before 37 weeks
• A noticeable decrease in your baby's movements
• If you simply think you are in labor or are unsure

What is the 5-1-1 rule for labor?

5-1-1 describes contractions about 5 minutes apart, each lasting about 1 minute, continuing for at least 1 hour. It is a common cue to head to the hospital for a first labor, but call your provider, who may use a different threshold such as 4-1-1.

How can I tell true labor from Braxton Hicks?

True labor contractions are regular, grow stronger, move closer together, and do not stop with rest or hydration. Braxton Hicks are irregular, do not steadily intensify, and usually ease when you move, change position, or drink water.

What should I do when my water breaks?

Call your provider or go to your delivery facility right away, even if you are unsure it is amniotic fluid. Note the time, color, and amount of fluid, since the risk of infection rises the longer labor takes to begin afterward.

When should I go to the hospital for labor?

Go when you reach the contraction pattern your provider gave you, often around 5-1-1 for a first labor, or right away if your water breaks, you have vaginal bleeding, you feel reduced fetal movement, or you have any signs of labor before 37 weeks.
