Membrane sweep when planning a VBAC

A sweep is a cervical examination intended to separate the membranes near the cervix and may encourage labour. For someone planning a vaginal birth after caesarean, the decision is part of a wider plan that considers the type of uterine incision, reasons for the earlier caesarean, current pregnancy findings, and the facilities available for labour care.

A sweep is not the same as using induction medicines or mechanically opening the cervix. Your team should explain whether the examination is appropriate, what monitoring is advised, and how a change in the plan would be handled. A previous caesarean makes personalised counselling especially relevant.

Bring your previous birth records if your maternity team does not already have them. Ask how the sweep fits with your intended VBAC timing and what signs should prompt a call. Afterward, keep track of contractions, bleeding, fluid loss, and your baby’s usual movements. Make sure you know where to attend if labour starts or symptoms change.

For background, see [Membrane Sweep](/treatments/pregnancy-and-birth-care/membrane-sweep/) and [Induction of Labour](/treatments/pregnancy-and-birth-care/induction-of-labour/).

Contact your maternity unit immediately for heavy bleeding, severe or persistent abdominal pain, leaking fluid, regular contractions, reduced fetal movement, dizziness, or feeling unwell. With a uterine scar, use the urgent contact plan your obstetric team gave you rather than relying on general advice.

Ask whether your uterine incision and current pregnancy make a sweep suitable, how labour will be monitored, which symptoms require urgent review, and what induction or caesarean options would be considered if labour does not start.
