more. 1  May be irregular at first and usually become regular. 2  Get longer, stronger, and closer together as time progresses. 3  Walking usually makes them stronger.

The Birth of Your Baby. The strong contractions you experience during active labor are your body's way of pushing your baby through the birth canal. During the birth process, your contractions may slow down to every two to five minutes, lasting 60 to 90 seconds.

At the beginning, your contractions may be very irregular. One contraction may be 15 minutes apart from the next or as close as 5 minutes. The length of the contraction is probably 30 seconds to one minute in length. As the first stage of labor progresses, your contractions get closer and more regular.

Mild contractions generally begin 15 to 20 minutes apart and last 60 to 90 seconds. You should go to the hospital once you reach active labor. For most women, active labor is characterized by strong contractions that last 45 to 60 seconds and occur three to four minutes apart.

Preterm contractions. Many contractions that occur after week 34 are random and irregular; these are known as Braxton-Hicks contractions. If contractions come regularly every 10 minutes or less rather than intermittently, you may be in preterm labor. Report any contractions to your doctor or midwife so she can determine what's happening.

When your contractions get closer together, you are farther along in the delivery phase of labor. At the beginning, the tightening or painful part of the contraction will last approximately 30 to 45 seconds, near the end the pain will be longer. A true contraction is usually at least 30 seconds long.

Try to walk and see if the contractions get stronger and more regular. Call your doctor when you are having contractions every 3-5 minutes that are lasting 45-60 seconds each for 1 hour. If you have given birth before, call when the contractions are every 5-7 minutes apart, lasting 45-60 seconds. Labor is often more intense and faster with subsequent pregnancies and after you break your bag of water. In active labor, your contractions will be every 2-3 minutes apart.

Prodromal labor can feel very much like active labor, yet is not consistently progressive. Prodromal labor contractions may begin hours or even days before active labor. They may feel like Braxton Hicks contractions or they may be quite a bit stronger. They are irregular in length, frequency and intensity. They may or may not be affected by your activity.
