What are Braxton Hicks contractions?

Braxton Hicks contractions are characterized as irregular, often painless contractions that can occur before the onset of true labor. They are sometimes referred to as "practice contractions" because they help prepare the uterus for the work of labor by toning the uterine muscles. These contractions can happen at any point in the second and third trimesters of pregnancy and do not follow a specific pattern or rhythm, differentiating them from true labor contractions, which are typically regular and become progressively stronger and more frequent.

Unlike painful contractions during labor, Braxton Hicks do not result in cervical dilation. They can serve as a helpful indicator to the expectant mother that her body is preparing for delivery but do not indicate that labor is imminent. Understanding the nature of these contractions is important for pregnant individuals and can help reduce anxiety about distinguishing between false labor and true labor signs.
