VBAC conversations: Questions About a Future Birth After Cesarean

A previous caesarean does not automatically determine how a future baby will be born. For many people, the discussion includes planning a vaginal birth after caesarean, called VBAC, and planning another caesarean. The right conversation starts with your history, the current pregnancy and what matters to you.

Bring the previous birth into the discussion

Ask for a review of why the earlier caesarean happened and the operation record. The incision in the uterus matters; its shape cannot be established by looking at the scar on your abdomen. Tell your team about other uterine surgery and any complications during recovery.

A prior vaginal birth, the reason for the caesarean and current pregnancy findings can affect the chance of vaginal birth. If the previous experience was difficult, our unplanned caesarean guide may help you identify questions you still want answered.

Separate a plan from an outcome

Planning to labour after a caesarean may be called a trial of labour after caesarean. VBAC describes the vaginal birth that can result. Labour can also end in another caesarean, so ask what circumstances would lead the team to recommend a change.

A successful vaginal birth avoids another abdominal operation and usually allows a quicker recovery. Labour that ends in an unplanned caesarean has a different risk profile. Population averages cannot guarantee your outcome, and a discussion should include both possibilities.

Compare the important risks

A rare but serious concern during labour is the previous uterine scar opening, called uterine rupture. Induction can change this risk and the chance of a successful vaginal birth; discuss the specific method if induction is proposed.

A repeat caesarean has surgical risks and can increase certain placental and surgical complications in future pregnancies. Ask how future family plans affect the comparison. Some histories, including a previous uterine rupture or certain uterine incisions, may make planned caesarean the recommended option.

Discuss where and how labour would be supported

Ask about a birth setting with access to emergency caesarean birth and the monitoring recommended during labour. Continuous monitoring of your baby’s heart rate is commonly advised. Pain relief, including an epidural, can still be discussed.

Your birth preferences can include communication, support and explanations if the plan changes. Monitoring does not remove the need to involve you in decisions.

Make a plan for different starting points

Clarify whom to call if labour begins or your waters break, what happens if labour has not started by the agreed review date, and how a new complication would affect options. If you choose a repeat caesarean, also ask what to do if labour starts before the booked day. Revisit the plan with your team as information changes rather than treating an early decision as unchangeable.
