Braxton Hicks contractions

Braxton Hicks contractions are temporary, irregular tightening of the uterine muscles that typically occur during pregnancy. Often called "practice contractions," they can start around the second or third trimester. These contractions help prepare the uterus for labor but do not cause actual labor or dilation of the cervix. They usually feel like mild, tightening sensations across the abdomen and may come and go unpredictably. Unlike true labor contractions, Braxton Hicks tend to be less intense, more irregular, and do not increase in frequency or intensity over time. They are a normal part of pregnancy and generally not a cause for concern.
