Having one C-section doesn't automatically mean every future delivery has to be a C-section. A vaginal birth after caesarean (VBAC) is a real option for many women — but whether it's right for you depends on specifics of your history and this pregnancy, which is why your doctor discusses it as a possibility to evaluate, not a promise to make.

Who is usually a good candidate

The most consistent candidate profile for VBAC is:

  • One prior C-section, generally with a low-transverse (side-to-side, lower uterine segment) incision — the most common type done today
  • No other reason a vaginal delivery would be discouraged this time around, such as placenta position issues or a repeat indication from before
  • A healthy, otherwise low-risk current pregnancy

The type of incision from your previous C-section matters more than most people expect — it's one of the first things your doctor checks when VBAC comes up, since it directly affects the safety of attempting labour.

Why it's called a "trial of labour," not a guarantee

If you and your doctor agree VBAC is reasonable to attempt, it's usually described as a "trial of labour after caesarean" (TOLAC) — meaning labour is allowed to proceed under monitoring, with the understanding that it may still end in a repeat C-section if labour doesn't progress safely. This framing isn't pessimism; it's accuracy. A trial of labour succeeds in a vaginal delivery for many women who attempt it, but not all, and knowing that going in makes the process easier to navigate emotionally either way.

Why it's monitored closely

The main risk being watched for during a trial of labour is uterine rupture at the site of the previous scar — uncommon, but the reason VBAC labours are typically managed in a hospital equipped to move to an emergency C-section quickly if needed. This is also why VBAC isn't something to plan for a home birth or a facility without surgical backup.

When a repeat C-section is advised instead

Your doctor is likely to recommend a planned repeat C-section rather than a trial of labour if:

  • Your previous incision was a "classical" (vertical, upper uterine) type, or the incision type is unknown
  • You've had more than one previous C-section, depending on the full picture
  • There's a current pregnancy-specific reason a vaginal delivery isn't advisable (independent of the VBAC question)

This isn't a rejection of VBAC as a concept — it's the same individualised evaluation applied the other way.

Frequently asked

Can I ask for a VBAC even if my doctor initially suggests a repeat C-section?

Yes — it's a conversation worth having explicitly. Bring your previous operative notes if you have them; the incision type recorded there is often the deciding detail.

Is VBAC riskier than a repeat C-section?

Each path carries its own considerations rather than one being universally "riskier" — a trial of labour has its own monitored risks, and a repeat C-section has the usual surgical-recovery considerations. This is exactly why the decision is individualised rather than standardised.

Does having a VBAC affect delivery choices for future pregnancies?

A successful VBAC generally supports the option of vaginal delivery again in a future pregnancy, but each pregnancy is still evaluated on its own facts at the time.

What if labour doesn't progress during a trial of labour?

Your team will move to a C-section if labour stalls or any monitoring concern comes up — this is the built-in safety net of attempting VBAC in a hospital setting, not a failure of the attempt.
