What characteristic defines true labor contractions?

True labor contractions are characterized by being regular and rhythmic. This consistent pattern is crucial because it indicates that the body is preparing for the labor process and signifies a progression toward cervical changes and eventual delivery. These contractions typically increase in intensity and frequency over time, distinguishing them from Braxton Hicks contractions, which are often irregular and can vary in intensity.

In true labor, the rhythmic nature of contractions helps in the dilation of the cervix and descent of the fetus, playing a fundamental role in the childbirth process. While contractions may initially be mild, they will usually become stronger and closer together as labor progresses, reflecting a clear and purposeful pattern associated with the laboring process.
