what is braxton hicks contractions

Braxton Hicks contractions, also known as "false" or "practice" contractions, are a normal part of pregnancy. They are sporadic contractions and relaxation of the uterine muscle, which help tone the uterus' muscles and prepare the cervix for birth. These contractions can be felt as a tightening or pressure in the abdomen and are described as irregular, usually lasting for about 30 seconds, and are generally uncomfortable but not usually painful. They are different from true labor contractions in terms of intensity, frequency, and regularity. Braxton Hicks contractions are not a sign of labor beginning and typically stop with a change in activity or position. If there is uncertainty about whether the contractions are Braxton Hicks or true labor contractions, it is recommended to contact a doctor or midwife for advice
