Preparing for VBAC: What to Know About Vaginal Birth After a Previous C-Section

Having a previous C-section does not automatically mean that your next baby must also be born by C-section. For some women, vaginal birth after C-section (VBAC) can be an option, depending on their previous surgery, current pregnancy, medical history, and the facilities available for labour and emergency care.

If you are considering VBAC, understanding your options early can help you have informed conversations with your obstetrician or maternity team.

This guide explains what VBAC means, what factors can affect your options, how to approach preparing for VBAC, what may happen during labour, and which questions to discuss with your healthcare provider.

What Is Vaginal Birth After C-Section?

Vaginal birth after C-section means giving birth vaginally after having previously delivered a baby by caesarean section.

VBAC is different from simply planning a vaginal birth because a previous C-section leaves a scar on the uterus. During labour, that scar needs to be considered when your healthcare team assesses the safest approach.

According to RCOG guidance, after one previous C-section, VBAC and planned repeat C-section can both be considered in appropriate pregnancies. Around 3 out of 4 women with one previous C-section who go into spontaneous labour give birth vaginally.

However, your individual likelihood of a successful VBAC can differ considerably.

VBAC Pregnancy: What Factors Does Your Doctor Consider?

Every VBAC pregnancy is different. Your doctor may review several factors before discussing whether planned vaginal birth is suitable.

These can include:

• Why you had your previous C-section
• The type of incision made on your uterus
• Whether you have previously had a vaginal birth
• Whether you have had one or more C-sections
• Any complications during your previous surgery or recovery
• Your current pregnancy and baby's position
• Placental location and other pregnancy complications
• Whether labour begins spontaneously or needs to be induced
• Your plans for future pregnancies
• The availability of emergency C-section and blood transfusion services

Whether you are considering C-Section vs. Normal delivery i.e. the type of uterine incision is particularly important. A previous classical incision involving the upper part of the uterus is generally considered a reason not to plan VBAC because of the higher risk associated with labour.

That is why your previous surgical records can be valuable when discussing birth after C-section.

Preparing for VBAC: Start With an Early Birth-Planning Conversation

One of the most useful steps in preparing for VBAC is discussing your birth options early rather than waiting until labour begins. Before taking any step ask yourself first the Pros and Cons of C-sec and Normal Delivery.

Ask your obstetrician or maternity team:

1. Am I a candidate for VBAC based on my previous C-section?
2. What type of uterine incision did I have?
3. Does my current pregnancy have any complications that affect VBAC?
4. What factors could increase my chance of needing another C-section?
5. How would induction of labour affect my options?
6. Where would you recommend I give birth?
7. What monitoring would I need during labour?
8. What would happen if labour does not start by my planned timeframe?
9. What pain-relief options would be available?
10. What circumstances would lead to an emergency C-section?

NICE recommends discussing the benefits and risks of planned VBAC and planned repeat C-section while considering the individual's circumstances, priorities and plans for future pregnancies.

Birth After C-Section: Reviewing Your Previous Birth Matters

Your previous birth experience is an important part of planning your next one.

If possible, discuss:

• The reason for your previous C-section
• How labour progressed, if you were in labour
• Whether your previous C-section was planned or emergency
• Whether there were complications
• How you recovered
• The type of uterine incision
• Any previous vaginal births

For example, a previous vaginal birth is associated with a higher likelihood of vaginal birth in a subsequent pregnancy. NICE specifically recommends informing women with a previous C-section and previous vaginal birth that they have a higher likelihood of vaginal birth than women without a previous vaginal birth.

Your previous C-section does not tell the whole story. Your current pregnancy also needs to be assessed.

Vaginal Birth After Cesarean: Understanding the Benefits and Risks

Vaginal birth after cesarean can have advantages when it is successful.

A successful vaginal birth generally avoids another abdominal operation and may allow a shorter physical recovery compared with a C-section. It may also reduce the number of uterine scars for people who plan to have more children.

However, VBAC also has risks that need to be understood.

The most important rare complication is uterine rupture, where the previous uterine scar separates during labour. NICE describes the risk as small but emphasizes that women should be informed about it when considering vaginal birth after a previous C-section.

Another possibility is that labour may not progress as expected and an emergency C-section may become necessary.

The decision therefore involves more than simply asking whether VBAC is possible. It involves considering the benefits and risks of both planned VBAC and planned repeat C-section in your particular circumstances.

VBAC Preparation: What Can You Do During Pregnancy?

There is no guaranteed way to make a VBAC happen. VBAC preparation is better viewed as preparing yourself physically, emotionally and practically for labour while keeping a flexible birth plan.

1. Attend regular prenatal appointments

Keep up with your antenatal care so your healthcare team can monitor your pregnancy and identify any changes that could affect your birth plan.

2. Understand your previous surgical history

If you do not know what type of uterine incision was used during your previous C-section, ask your healthcare provider whether your surgical records can be reviewed.

3. Stay appropriately active

If your doctor says exercise is appropriate for you, regular pregnancy-safe movement can help you maintain strength, mobility and general wellbeing.

Pregnancy-specific activities such as walking and medically appropriate prenatal exercise can form part of a healthy pregnancy routine.

4. Work on relaxation and breathing

Labour can be physically and emotionally demanding. Practising calm breathing and relaxation techniques during pregnancy can give you tools to use during contractions.

5. Prepare for different outcomes

A VBAC birth plan should include your preferences while acknowledging that labour can change.

Preparing emotionally for both vaginal birth and a possible repeat C-section can reduce the feeling that an unexpected change means your birth experience has "failed."

6. Discuss pain relief in advance

Having a previous C-section does not mean you cannot discuss different pain-relief options. NICE recommends supporting informed choice about pain relief for women labouring after a previous C-section.

VBAC Delivery: What Happens During Labour?

A planned VBAC delivery generally requires a maternity setting where appropriate monitoring and emergency C-section services are available.

NICE recommends electronic fetal monitoring during labour for women planning vaginal birth after a previous C-section and recommends care in a unit with immediate access to C-section and on-site blood transfusion services.

Your care team may monitor:

• Your baby's heart rate
• Your contractions
• Your labour progression
• Your pain and other symptoms
• Your overall condition

The reason for close monitoring is not to make labour unnecessarily restrictive. It is because changes during labour can sometimes indicate a problem involving the uterine scar or another complication.

If an emergency C-section becomes necessary, your medical team can respond quickly.

What About Induction During a VBAC Pregnancy?

Induction requires particular discussion when you have a previous C-section.

According to NICE, induction after a previous C-section can increase the risk of emergency C-section and uterine rupture. Different induction methods also have different considerations, so your healthcare provider should discuss the available options with you.

This does not mean induction is automatically impossible. Instead, the decision should be individualized based on your pregnancy, cervical readiness, reason for induction and available monitoring and emergency care.

If labour has not started by the timeframe discussed with your doctor, your birth options may need to be reviewed again.

Pregnancy After C-Section: Looking Beyond This Birth

A pregnancy after C-section involves more than planning the immediate birth.

Your healthcare team may also consider how your current delivery could affect future pregnancies.

Each additional C-section can create more scar tissue and can affect risks in future pregnancies. RCOG notes that future pregnancy and birth planning should be part of the discussion when considering VBAC versus another planned C-section.

If you hope to have more children, tell your healthcare provider. Your future family plans can be relevant when discussing birth options.

Can Prenatal Yoga Be Part of VBAC Preparation?

If your healthcare provider has cleared you for exercise, pregnancy-specific movement can be included as part of general VBAC preparation.

Prenatal yoga may help you maintain mobility, practise breathing and relaxation, and prepare physically for the demands of labour. However, it should not be presented as a method that guarantees vaginal birth after a C-section.

Pregnancy101's prenatal yoga classes are designed around pregnancy-specific movement, breathing and labour preparation.

Always discuss exercise with your maternity provider if you have complications, activity restrictions or concerns related to your previous C-section.

How to Build a Practical VBAC Birth Plan

A VBAC birth plan should be specific enough to communicate your preferences but flexible enough to account for changes in labour.

Your VBAC birth plan can include:

Before labour

• Preferred hospital or maternity unit
• Doctor or maternity team
• Emergency contact numbers
• Previous C-section records
• Questions about induction
• Preferred pain-relief options

During labour

• Preferred movement and positions
• Breathing and relaxation techniques
• Support person
• Pain-relief preferences
• Monitoring expectations
• What you would like your team to explain before interventions

If a C-section becomes necessary

• What circumstances would lead to the recommendation
• Who will explain the situation
• Which support person can be present
• Your preferences for communication and immediate postpartum care

Having a flexible plan does not mean expecting complications. It means knowing your options before labour begins.

When May VBAC Not Be Recommended?

VBAC is not appropriate for everyone.

According to RCOG guidance, VBAC is generally not advised after certain situations, including:

• Three or more previous C-sections
• A previous uterine rupture
• A previous classical C-section incision involving the upper uterus
• A current pregnancy complication that requires a planned C-section

The exact recommendation depends on your medical history and current pregnancy, so your obstetrician should assess your individual circumstances.

Final Thoughts

Preparing for vaginal birth after C-section is not about finding a guaranteed formula for vaginal birth. It is about understanding your medical history, reviewing your current pregnancy, discussing the benefits and risks of your options, and making a flexible plan with your maternity team. That’s where Rita’s Pregnancy 101 comes in.

Some women may be suitable candidates for VBAC, while others may be advised to have a planned repeat C-section. The safest option can differ from one pregnancy to another.

If you are considering birth after C-section, start the conversation early. Bring your previous surgical information, ask questions about your individual circumstances, and make sure you understand what will happen during labour and if plans need to change.

The goal of VBAC preparation is not to predict exactly how your birth will unfold. It is to help you enter labour informed, prepared and supported.

Frequently Asked Questions About Vaginal Birth After C-Section

1. What is vaginal birth after C-section?

Vaginal birth after C-section (VBAC) is a vaginal delivery after a previous caesarean birth. Whether VBAC is suitable depends on your previous surgery, current pregnancy and individual medical circumstances.

2. Is VBAC possible after one C-section?

Yes, VBAC can be an option for many women after one previous C-section. RCOG states that around 3 out of 4 women with one previous C-section who go into spontaneous labour give birth vaginally, although individual circumstances can change the likelihood and safety of VBAC.

3. What does preparing for VBAC involve?

Preparing for VBAC involves discussing your previous C-section, reviewing your uterine incision, understanding your current pregnancy, staying appropriately active if medically cleared, learning about labour and pain-relief options, and creating a flexible birth plan with your healthcare team.

4. Can I have a VBAC delivery if I need induction?

Induction may sometimes be considered after a previous C-section, but it requires careful discussion because induction can increase the risk of uterine rupture and emergency C-section. Your doctor should explain the available methods and their risks and benefits.

5. Does a previous C-section affect my next pregnancy?

A pregnancy after C-section requires consideration of the previous uterine scar and how it may affect pregnancy and birth planning. Your healthcare team will assess your individual circumstances and discuss whether VBAC or planned repeat C-section is appropriate.

6. Can prenatal yoga help with VBAC preparation?

Prenatal yoga may support general strength, mobility, relaxation and breathing during pregnancy when medically appropriate. However, it cannot guarantee a vaginal birth after cesarean. Speak with your healthcare provider before beginning or continuing an exercise programme.

7. What should I ask my doctor before planning VBAC?

Ask whether you are a suitable candidate, what type of uterine incision you had, how your previous birth affects your options, how induction would affect your plan, what monitoring is required, where you should give birth, and what would happen if an emergency C-section became necessary.
