What is the difference between Braxton Hicks contractions and true labor?

Braxton Hicks contractions differ from true labor in several key aspects regarding their regularity, intensity, and effect on the cervix. Braxton Hicks contractions are mild, irregular contractions that typically occur after the first trimester and do not cause cervical changes, whereas true labor contractions are regular, increase in intensity and frequency over time, and lead to the thinning and dilation of the cervix in preparation for birth [2].

It is important to understand these differences to help a pregnant person determine if labor has actually begun or if these are merely preparatory contractions. These preparatory contractions can persist for days before true labor begins [2].

Characteristics of Braxton Hicks Contractions

Braxton Hicks contractions are known as false or preparatory contractions and are characterized by several features that help distinguish them from true labor. These contractions are often short and painless and may occur at any time after the first trimester [2]. A key feature is that they do not occur at regular intervals and do not increase in strength or frequency over time. They are also not typically accompanied by bleeding or fluid leakage from the vagina, and they do not noticeably affect fetal movement [2]. Braxton Hicks contractions usually stop or decrease in intensity when changing position or walking, and they do not lead to any changes in the cervix, such as thinning or dilation [2].

Signs of True Labor

True labor is characterized by regular contractions that increase in strength and frequency over time [1]. These contractions do not stop regardless of activity or changes in position and usually radiate to the lower back and upper abdomen [2]. The contractions become more intense, making it difficult to talk or laugh during them [2]. Other signs of true labor include the leakage of fluid or vaginal bleeding, feelings of mild lower back pain, and abdominal cramps [1]. This stage of labor begins when the cervix becomes thinner and dilates to approximately 10 centimeters to allow the baby to pass [1].

When to Contact Your Healthcare Provider

It is essential to contact your healthcare provider immediately if you experience any of the following signs, even if it is not yet time for delivery: leakage of amniotic fluid, vaginal bleeding other than light spotting, or decreased fetal movement [2]. You should also call your doctor if you are experiencing painful, regular contractions every 5 to 10 minutes for 60 minutes, or contractions lasting 60 to 90 seconds [2]. In general, if you are unsure whether you are in true labor or not, it is always best to contact your healthcare provider for the necessary guidance [2].
