Braxton Hicks contractions are common sensations during pregnancy. They often mimic labor, causing curiosity or concern for expectant parents. Understanding these “practice” contractions can help alleviate worries and provide clarity.
What Are Braxton Hicks Contractions?
Braxton Hicks contractions are the uterus’s way of preparing for labor, also known as “false labor.” They involve a tightening sensation across the abdomen as the uterine muscles contract and then relax. These sensations can begin as early as six weeks into pregnancy, although they are more commonly felt in the second or third trimester.
These contractions typically feel like a mild cramping or a generalized hardening of the belly. While they can be uncomfortable, they are generally not painful and should allow you to continue talking and walking. These contractions are thought to tone uterine muscles, aid blood flow to the fetus, and condition the body for childbirth.
Understanding Their Frequency
It is common to experience Braxton Hicks contractions frequently, even daily, particularly as pregnancy progresses into the later stages. This increased frequency is a normal part of the body’s preparation for labor. Unlike true labor, these contractions remain irregular and do not consistently increase in intensity or duration.
Several factors can influence the frequency of Braxton Hicks contractions. Dehydration, increased physical activity by the pregnant person or baby, sexual intercourse, a full bladder, stress, and inadequate sleep can contribute to more frequent occurrences. While these contractions may become more noticeable and frequent closer to the due date, they typically subside with changes in position or activity, or with rest and hydration.
When to Seek Medical Advice
Differentiating Braxton Hicks from true labor contractions is important. Braxton Hicks contractions are irregular, do not get progressively stronger or closer together, and generally do not dilate the cervix. True labor contractions, however, become more regular, increase in intensity and duration, and cause changes to the cervix.
You should contact your doctor or midwife if contractions become regular, lasting approximately 60 seconds and occurring every three to five minutes. Seek immediate medical attention if contractions are accompanied by vaginal bleeding, a gush or trickle of fluid (indicating your waters may have broken), or a decrease in fetal movement. If you are less than 37 weeks pregnant and experience regular contractions or any of these warning signs, prompt medical evaluation is advised to rule out preterm labor.
