A cervical check is a routine part of prenatal care in later pregnancy, involving a manual examination to assess cervical changes. This procedure helps healthcare providers understand the body’s readiness for labor. Many wonder if it can initiate labor as pregnancy nears its conclusion.
What is a Cervical Check?
A cervical check, also known as a digital vaginal exam, is a manual procedure performed by a healthcare provider. During this examination, the provider inserts gloved fingers into the vagina to feel the cervix and assess its readiness for childbirth.
The healthcare provider evaluates the cervix for dilation, which is how open it is, measured in centimeters from 0 to 10. They also check for effacement, or how thin the cervix has become, typically expressed as a percentage from 0% to 100%. Additionally, the consistency of the cervix (whether it’s firm or soft) and its position (posterior or anterior) are noted. The baby’s station, indicating how low the baby’s head is in the pelvis, is also assessed.
Does a Cervical Check Induce Labor?
A routine cervical check generally does not induce labor. While the examination involves some cervical manipulation, it typically does not trigger the biological processes required for true labor. The body initiates labor when physiologically ready, influenced by hormonal and physical factors.
Some individuals might experience mild contractions or discomfort immediately following a cervical check, such as light cramping or pressure. These sensations are usually temporary and do not signal the onset of true labor contractions. They are due to physical stimulation of the cervix and typically resolve within a few hours.
True labor involves consistent, intensifying contractions that lead to progressive changes in the cervix, such as dilation and effacement. A cervical check provides a snapshot of the cervix’s current state but does not reliably predict when labor will start. It is common for a cervix to show some dilation or effacement for weeks before labor actually begins, or for labor to start suddenly with no prior cervical changes.
Understanding Membrane Sweeping
Membrane sweeping, also called a “stretch and sweep” or “cervical sweep,” is distinct from a standard cervical check. While both involve an internal examination, a membrane sweep is an intentional intervention aimed at encouraging labor, typically offered when a pregnancy is at or past term.
During a membrane sweep, the healthcare provider inserts a gloved finger through the cervix and sweeps it around the inside of the lower uterine segment. This action separates the amniotic sac from the uterine wall. This separation can stimulate the release of prostaglandins, hormones that help soften, thin, and dilate the cervix, potentially initiating contractions and labor.
Unlike a routine cervical check, which is purely for assessment, a membrane sweep aims to promote labor. It is considered a low-risk method that can sometimes help avoid medical induction. While effective for some, it does not guarantee labor onset and may require a partially dilated cervix.
What to Expect After a Cervical Check
After a cervical check, mild sensations are common and normal. Many notice light spotting, appearing as pink or brownish discharge, often called bloody show. This spotting occurs due to sensitive cervix manipulation and typically subsides within 24 to 48 hours.
Mild cramping or pressure in the pelvic area is also a frequent post-check experience. These sensations are usually temporary and distinct from the intensifying contractions of true labor. The discomfort arises from physical stimulation of the cervix and surrounding tissues.
If any symptoms beyond mild spotting or cramping occur, such as heavy bleeding, severe or worsening pain, or signs of infection like fever or unusual discharge, it is important to contact a healthcare provider. These signs are not typical and warrant further evaluation.
