Cervical dilation refers to the opening of the cervix, a process in preparing the body for childbirth. As pregnancy progresses, many expectant individuals wonder about their body’s readiness for labor. This article explores what it means if cervical changes, specifically dilation, begin around 35 weeks of pregnancy. Understanding these shifts can help clarify what to expect as the due date approaches.
Cervical Changes Before Labor
Cervical dilation describes the widening of the cervix, measured in centimeters. Cervical effacement refers to the thinning and softening of the cervix, measured as a percentage from 0% to 100%. Both processes are part of the body’s preparation for childbirth. These changes allow the cervix to open enough for the baby to pass through.
These preparatory changes can begin weeks before true labor starts. The cervix might soften, thin, and even begin to open a small amount without noticeable contractions or symptoms. This indicates the body is undergoing adjustments in anticipation of labor. These early changes often occur without the pregnant individual being aware of them.
Dilation at 35 Weeks
It is common for some cervical effacement and minor dilation, often one to two centimeters, to occur in late pregnancy. This can happen around 35 weeks, especially in individuals who have given birth before. This early dilation indicates the body is undergoing a preparatory phase rather than signaling imminent labor. The cervix is beginning its process of readying for childbirth.
Experiencing this level of dilation at 35 weeks does not necessarily mean labor will begin immediately. True preterm labor involves regular, strong uterine contractions that lead to progressive changes in the cervix before 37 weeks of gestation. These contractions are distinct from the sporadic, irregular contractions known as Braxton Hicks, which are practice contractions that can cause minor cervical changes without leading to active labor. Minor dilation alone at 35 weeks, without other signs of active labor, is considered a normal part of late pregnancy progression.
When to Contact Your Doctor
Any concerns regarding cervical changes or new symptoms during pregnancy should always prompt a discussion with a healthcare provider. While minor dilation at 35 weeks can be part of the body’s preparation, certain signs warrant immediate medical attention. These symptoms could indicate preterm labor or other complications requiring assessment. A healthcare professional can evaluate the situation and provide personalized guidance.
Specific signs that require immediate contact with your doctor include regular, painful contractions that become stronger and closer together. Vaginal bleeding, particularly more than light spotting, is a concerning symptom. A sudden gush or continuous trickle of fluid from the vagina could indicate a rupture of membranes. Persistent lower back pain or increased pelvic pressure, along with changes in vaginal discharge such as it becoming watery, bloody, or mucus-like, also require medical evaluation.
