Can I Have a VBAC? What Actually Matters (Evidence-Based Guide)
You’ve had a cesarean. Maybe it was planned, maybe it wasn’t. But you remember the moment things shifted. The conversation changed. The plan changed. And suddenly, a C-section became the safest way to bring your baby into the world.
You did what was necessary. And now, as you think about your next birth, there’s a question steady in your mind:
Can I have a VBAC?
It’s one of the most common questions people ask after a cesarean.
It’s a question we’ve walked through with many clients. I know it can feel both hopeful and uncertain at the same time.
If you’re wondering whether VBAC is an option for you, you’ve probably noticed the answers aren’t always clear. One source says you’re a great candidate. Another says it depends. Your provider may have given you a cautious “we’ll see.”
It’s a lot to hold, especially when this decision carries such emotional and physical weight.
Choosing to pursue a VBAC doesn’t come down to simple yes-or-no answers. It’s shaped by a combination of factors unique to you: your previous birth, your current pregnancy, and your overall health.
Cesarean births happen for many reasons, and most are outside of your control. A VBAC is a decision that deserves thoughtful, individualized care.
In this guide, we’ll walk through what actually matters using a clear, evidence-based checklist to help you better understand your options and feel more prepared for conversations with your provider.
What Is a VBAC? Understanding VBAC vs. TOLAC
You’ll often hear two terms when talking about birth after a cesarean: VBAC and TOLAC. They’re related, but don’t mean exactly the same thing.
VBAC stands for vaginal birth after cesarean. It describes the outcome of having a vaginal birth after a previous C-section.
TOLAC, or trial of labor after cesarean, refers to the process. It means choosing to go into labor with the intention of having a vaginal birth after cesarean.
If labor progresses and a vaginal birth happens, that’s considered a successful VBAC. If complications arise or labor doesn’t progress as expected, a repeat cesarean may be needed.
This distinction can be helpful because when providers talk about VBAC, they’re often talking about whether a TOLAC is appropriate in your situation.
What Factors Are Considered When Evaluating VBAC
If you’re wondering whether VBAC is an option for you, understanding these factors can bring a lot more clarity.
While there’s no single thing that determines if VBAC is right for you, there are a few key factors that pregnant families and providers consistently look at.
The Type of Uterine Incision You Received – But it’s Not the Whole Story
Most cesareans today are performed with a low transverse incision, a horizontal cut across the lower part of the uterus. This type of scar is associated with the lowest risk of uterine rupture and is generally considered the most favorable for VBAC.
There are other types of uterine incisions that are often described as carrying more risk during labor—such as a classical (high vertical) incision. Because of this, some providers may be less likely to recommend VBAC in these situations.
However, it’s important to know that the research on many of these incision types—especially less common variations like T-shaped, J-shaped, or extended incisions—is limited and not always clear-cut. In fact, some widely quoted risks are based on small or older studies, and there is still a lot we don’t fully know.
Because of this, VBAC is not always a simple yes-or-no decision based on incision type alone. Many factors matter, including the details of the original surgery, how the uterus healed, overall health, and the experience and support of the provider.
There are individuals with more complex or uncommon uterine scars who, with careful evaluation and a supportive care team, do go on to have safe VBACs.
In my own personal experience, I had a very unusual incision and was still able to have a VBAC with a supportive provider.
How Many Cesareans You’ve Had
With multiple cesareans, the picture becomes more nuanced. Some providers may support a trial of labor after more than one cesarean, while others may take a more cautious approach.
Time Between Pregnancies
After a cesarean, your uterus needs time to heal fully. Even if you feel physically recovered, healing at the uterine level takes longer.
Shorter intervals between pregnancies have been associated with a higher risk of complications in some studies. However, risk doesn’t change at a specific cutoff, and individual circumstances play an important role.
The Reason for Your Previous Cesarean
If your cesarean was due to something like your baby’s position (for example, breech), that situation may not repeat itself, which can make a VBAC more likely.
If it were related to how your labor progressed, that might require a closer look. It all depends on whether those factors are likely to come up again.
Your Current Pregnancy
Factors related to your current pregnancy can also play a role. Things like estimated baby size, how far along you are, and the position of the placenta may all be considered when evaluating your options. Estimated baby size, in particular, is not always precise and is just one part of the overall picture.
In some situations, such as placenta previa, a planned cesarean is typically recommended regardless of prior birth history. In others, these factors simply help guide a more individualized conversation about what approach makes the most sense for you.
Your Overall Health
Certain conditions, such as preeclampsia, may influence the likelihood of a VBAC or lead some providers to recommend a repeat cesarean.
These are the same things we walk through with clients when we’re talking about whether a VBAC makes sense for them. They’re a starting point to help you understand what to expect, not a final answer.
Why VBAC Decisions Aren’t Always Straightforward
As you look through these factors, you may notice some offer a clear answer while others don’t.
Two people can have similar histories and receive different recommendations. How everything comes together in your specific situation shapes your decision.
You may have been told you are or aren’t a “VBAC candidate,” but those labels don’t always reflect the full picture.
Provider experience and comfort level can play a major role. Some providers are more open to supporting VBAC in complex situations, while others are not. This can sometimes reflect differences in training or hospital policies, not just individual risk.
This is why having the right support and information matters. This isn’t a decision you’re meant to navigate perfectly or alone.
What Are the Benefits of a VBAC?
For many people, choosing to pursue a VBAC comes with meaningful benefits, both physically and emotionally.
A vaginal birth avoids abdominal surgery, which often means a shorter recovery and fewer potential complications. This matters when you’re caring for a newborn.
A VBAC can also lower the risk of complications in future pregnancies. With each additional cesarean, the chances of issues like placenta-related complications tend to increase.
There can be important benefits for the baby as well. Babies born vaginally may have an easier transition at birth, particularly when it comes to breathing and clearing fluid from their lungs. They also benefit from the mother’s microbiome as they pass through the vagina. This early exposure helps introduce beneficial bacteria that support the development of the baby’s gut and immune system in the early days of life.
And for some, the benefits move beyond physical. A VBAC can offer a different kind of birth experience, one that feels more aligned with how they hoped to give birth, or more empowering after a previous cesarean.
That said, these benefits are just part of the bigger picture. What matters most is how they fit alongside your individual circumstances and what feels right for you.
Alongside these benefits, it’s also important to understand the potential risks.
What Are the Risks of a VBAC?
When we talk with clients about VBAC, we always make space to look at the risks clearly and without fear.
Some risks are similar to any labor and delivery, including infection or bleeding. There’s also a possibility that labor doesn’t progress as expected, which may lead to a repeat cesarean after attempting a TOLAC.
One of the more serious risks we discuss is uterine rupture, where the previous cesarean scar opens during labor. This is very rare, but it can be dangerous for both mom and baby. The overall likelihood of this happening remains low, especially for those with a prior low transverse incision.
While uterine rupture is often the most discussed risk, it’s important to look at the full picture. Repeat cesareans also carry risks, and those risks tend to increase with each surgery. Comparing both options side by side can help you better understand what feels right for you.
In my experience, what matters most is knowing how the risks apply to you. For many people, the overall risks of VBAC remain low. And with the right planning and support, a VBAC can be a safe and reasonable option.
How to Approach Your VBAC Decision
After we look at all these factors together, this is usually the point where clients ask, “So…what should I do?”
And the answer is…it depends.
Generally, researchers estimate success rates at around 60-80% for those who plan a trial of labor after a cesarean. What matters more is how your specific history, your current pregnancy, and your overall health come together in your situation.
There is no perfect answer. What feels supported and safe to you? What feels aligned with your goals for this birth?
Ultimately, you’re gathering information to make a decision you feel confident in.
Support Makes a Difference
You don’t have to navigate this important decision alone.
Your provider plays an important role in helping you understand your options, especially when they’re open to VBAC and willing to have thoughtful, informed conversations with you. But support doesn’t stop there.
As doulas, our role is to help you move through this process feeling clear, prepared, and supported at every step. That can look like talking through your options, helping you understand what questions to ask, and staying grounded in what matters most to you as your pregnancy and birth unfold.
Consistent, experienced support can make a meaningful difference in how you move through this decision. Whether you 100% know you are planning to try for a VBAC or are still sorting through your options, you can move forward with confidence.
The truth is, many people are told they are “not a candidate” for VBAC based on general guidelines that don’t always reflect their individual situation. Having the right information—and the right support—can make all the difference in understanding what’s truly possible for you.
