What is a "contraction"?
A contraction is a tightening and relaxing of the muscles in the uterus that helps to push the baby out during labor. These muscle movements create pressure and gradually open the cervix, the lower part of the uterus that connects to the birth canal. The cervix must open to allow the baby to pass through during delivery. Contractions occur in a regular pattern and become stronger and more frequent as labor progresses. They help move the baby down the birth canal and make the delivery process easier.
