Contractions can be defined as the movement of uterine muscles at regular intervals of time, especially during labor. Although contractions are associated with labor, one can experience different types of them at different intensities and periods.

Why Do Contractions Last So Long?

One can experience the tightening and hardening of the stomach from the early stages of pregnancy. The body prepares itself for the stressful event of baby delivery. Contractions get stronger, longer, and more painful at the end of pregnancy to properly facilitate the arrival of the kid.

During the first stages of labor, the cervix starts to dilate with minor contractions. The contractions cause the cervix to get thinner and shorter to prepare for delivery. As the cervix dilates up to 6 centimeters, the contractions get stronger and more regular.

The active labor phase is also accompanied by vaginal discharge and can last for 4 to 8 hours. The transition period is comparatively shorter but more intense. During this period, the cervix dialates from 8 to 10 centimeters with the help of overlapping contractions.


Contractions are the movements of uterine muscles that last for anything between 30 to 120 seconds. These movements facilitate the delivery of the baby at the end phase of pregnancy. However, not all contractions lead up to true labor and are called Braxton-Hicks contractions.

Contractions occur in patterns with regular intervals in between. The intervals can be 2 to 12 minutes long. Contractions get intense at the end of the transition phase and may also overlap to obtain successful child delivery.
