Per Vaginal Examination in Pregnancy: Why It Is Done During the 8th Month

A Per Vaginal (PV) Examination is a routine medical examination performed by an obstetrician or gynaecologist during the later stages of pregnancy. It helps assess the condition of the cervix, birth canal, and pelvis to determine how your body is preparing for labour. The examination is usually recommended during the 8th or 9th month of pregnancy or whenever your doctor needs to evaluate labour readiness. During the procedure, the doctor gently examines the cervix using sterile gloves to check for important changes such as cervical effacement (thinning), cervical dilatation (opening), and the baby's descent. A PV examination also helps identify concerns such as abnormal vaginal discharge, infection, or leaking amniotic fluid. The information gathered allows your doctor to make informed decisions and provide the safest care for both mother and baby. When performed by a qualified obstetrician, a Per Vaginal Examination in Pregnancy is a safe and important part of antenatal care that helps ensure a smoother and safer delivery.

During the 8th month of pregnancy, your body begins preparing for labour, making regular antenatal check-ups even more important. A Per Vaginal (PV) Examination helps your obstetrician assess whether your body is ready for a safe vaginal delivery and identify any concerns that may require medical attention. One of the primary reasons for the examination is to evaluate the cervix, checking whether it has started to soften, thin (efface), or open (dilate) in preparation for childbirth. The doctor also assesses the birth canal and pelvic bones to determine if there is adequate space for the baby's head to pass through during delivery. In addition, a PV examination helps detect signs that labour may be approaching, such as the "show" (blood-tinged mucus), abnormal vaginal discharge, or possible amniotic fluid leakage. Identifying these changes early allows your doctor to monitor your pregnancy closely and recommend the most appropriate care.

A Per Vaginal (PV) Examination provides valuable information about how your pregnancy is progressing and whether your body is preparing for labour. During the examination, your obstetrician carefully assesses several important factors that help determine the safest approach for delivery. The doctor first examines the cervix to check whether it has started to soften, thin (cervical effacement), or open (cervical dilatation), which are natural changes that occur as labour approaches. Next, the doctor evaluates the birth canal and pelvic bones to determine whether there is enough space for the baby's head to descend during a vaginal delivery. This assessment helps identify any factors that may affect the baby's passage through the pelvis. The examination also includes checking for abnormal vaginal discharge, signs of infection, blood-tinged mucus (commonly called the "show"), or amniotic fluid leakage, which may indicate that labour is approaching or that further medical evaluation is required.

One of the most important things your doctor checks during a Per Vaginal (PV) Examination is cervical effacement. Effacement refers to the softening and thinning of the cervix as your body prepares for labour. Throughout most of pregnancy, the cervix remains firm and closed to protect your baby. As delivery approaches, it gradually becomes softer and thinner, allowing it to prepare for childbirth. Your obstetrician evaluates the degree of cervical effacement to understand whether labour is approaching and how your body is progressing. Every pregnancy is different, and your doctor will explain your examination findings and guide you through the next steps based on your individual condition.

In addition to checking the cervix, your doctor also evaluates the pelvic bones and birth canal during a Per Vaginal (PV) Examination. This helps determine whether there is adequate space for the baby's head to move through the pelvis during a vaginal delivery. The doctor gently assesses the shape of the pelvis and checks for any prominent or narrow bony structures that could affect the baby's descent during labour. This examination is only one part of your overall pregnancy assessment and is considered alongside your baby's position, medical history, and other clinical findings.

A Per Vaginal (PV) Examination also helps your doctor identify important signs that may indicate labour is approaching or that further medical attention is needed. A blood-tinged mucus discharge, often called the "show," is a common sign that the cervix is beginning to prepare for labour. Your doctor also checks for signs of infection if the vaginal discharge appears unusual in colour, consistency, or has an unpleasant odour. Another important concern is amniotic fluid leakage. If you notice a continuous flow of clear, watery fluidoften described as resembling tender coconut waterit could indicate that the amniotic sac has ruptured. This requires immediate medical evaluation to ensure the safety of both mother and baby.

As you enter the 8th and 9th months of pregnancy, it is important to pay close attention to any new or unusual symptoms. While some changes are a normal part of pregnancy, others may indicate that labour is approaching or that you need immediate medical attention. Seek medical advice immediately if you notice:

• Watery leakage from the vagina
• Blood-tinged mucus (show)
• Thick, curdy white discharge
• Regular or severe abdominal pain
• Reduced baby movements

Early medical evaluation can help identify potential complications and ensure timely care for both mother and baby.

Yes. A Per Vaginal Examination is generally safe during pregnancy when performed by a qualified obstetrician or gynaecologist. It is a routine part of antenatal care, particularly during the later stages of pregnancy, to assess your body's readiness for labour. Many expectant mothers worry that the examination may harm the baby or trigger labour. However, the procedure is performed gently using sterile gloves and follows standard medical protocols to ensure the safety of both mother and baby. It usually takes only a few minutes and may cause mild pressure or temporary discomfort. Your doctor recommends a PV examination only when it is medically necessary to assess cervical changes, labour progress, pelvic readiness, or symptoms such as abnormal discharge or amniotic fluid leakage.
