Braxton Hicks contractions are the body's natural, often gentle, way of preparing the uterus for the work of labor, distinct from true labor contractions. As a trained full spectrum doula, I often hear from clients who are curious, and sometimes a little anxious, about these sensations. Understanding what they are can bring a lot of calm and clarity during your pregnancy.
What it is
Braxton Hicks contractions are irregular, typically painless or mildly uncomfortable uterine tightenings that usually begin around 16–24 weeks of pregnancy, becoming more noticeable as you move into your third trimester. Think of them as your uterus's practice runs, getting ready for the main event. It's important to know that if these contractions remain irregular, brief, and stop when you rest or hydrate, they are generally not a sign that labor is starting. Leading organizations like ACOG and NHS agree on this point: in low-risk pregnancies, there's no evidence that Braxton Hicks cause cervical changes or trigger preterm labor.
These practice contractions can become more frequent in subsequent pregnancies, as your body has been through this before. Certain activities can also trigger them, such as physical activity, having a full bladder, sexual activity, or even dehydration. Just as you might notice shifts in your body like increased fatigue or even Pregnancy Insomnia, Braxton Hicks are another common, normal physiological shift.
