Which of the following describes Braxton Hicks contractions?

Braxton Hicks contractions are characterized by their irregular nature and lack of significance in relation to actual labor. These contractions are often referred to as "practice contractions" and can occur throughout pregnancy, although they become more noticeable in the second and third trimesters. Unlike true labor contractions, Braxton Hicks are typically not associated with cervical change or the progression of labor; they do not represent a regular pattern and are generally not painful. They serve to prepare the uterus for the eventual labor process without indicating that labor is imminent. The irregular and non-labor signaling qualities of these contractions distinguish them from other types of contractions experienced during true labor.
