<prompt> Answer this question truthfullyHow would you define Braxton Hicks contractions?  <response>: <reason> Braxton Hicks contractions are uterine contractions that occur without any cervical changes. They are often described as false labor and can be felt as a tightening or hardening of the uterus. Unlike true labor contractions, Braxton Hicks contractions are typically irregular and do not increase in frequency or intensity over time. They are a normal part of pregnancy and can begin as early as the second trimester, but are most commonly experienced in the third trimester.
