Many women have healthy pregnancies after a C-section. However, it is important to be aware of certain risks during a second pregnancy. Thinking about getting pregnant again? Here is what you should watch for. Knowing these risks early can help you and your doctor plan a safer, better supported pregnancy from the very start. Read on to know more about it, as we reached out to an expert who explained the required waiting period and who's at higher risk to watch more closely.
What Are the Risks of Pregnancy After a C-Section?
Dr Shobha Gupta, Medical Director and IVF Expert at Mother's Lap IVF Centre, New Delhi, explains that a few specific risks are worth knowing about:
- The primary concern is uterine scar rupture, as the scar from the previous C-section may become weak and, in rare cases, rupture during labour or pregnancy.
- Placenta accreta or praevia, where the placenta may attach too low or too deeply in the scarred uterine wall, putting the mother at higher risk of bleeding
- Increased risk of having another caesarean section (C-section); however, if conditions are right, many women can have a vaginal birth after caesarean (VBAC)
- Ectopic pregnancy, although very rare, may embed itself into the C-section scar. Hence, early detection is important.
According to a 2024 Experimental and Therapeutic Medicine review, researchers looked at 19 studies comparing IVF outcomes in women with a previous C-section versus those with a prior natural vaginal delivery.
They found that women with a history of cesarean section had decreased clinical pregnancy, live birth, and implantation rates, as well as decreased multiple pregnancy rates. Women who had previously had a caesarean section were also eight times more likely to have their embryos transferred, which was also significantly more difficult.
Based on these findings, the researchers suggest doctors should counsel women with a history of C-section about these possible effects before starting fertility treatment, so they can plan and set expectations accordingly.

Does a C-Section Affect Your Fertility?
Not directly in most cases, according to Dr Gupta. However, some women might find it slightly harder to conceive. This can happen due to issues like pelvic scarring, infections, or a small pouch at the scar site called an isthmocele.
According to a 2026 study published in Frontiers in Medicine, researchers looked at how a prior C-section can lead to fertility troubles caused by a "niche," a small unhealed pouch in the uterine scar tissue. This niche can trap fluid and blood, creating chronic inflammation that makes it harder for an embryo to implant.
In this study, doctors treated over a thousand women with this scar defect using a corrective vaginal repair surgery. Among those trying to conceive again, close to half became pregnant. So while a C-section scar itself doesn't always cause fertility problems, in some women it can create physical changes that do, and those changes are often treatable with surgery.
How Long Should You Wait Before Trying Again?
Dr Gupta recommends giving the body adequate time to heal before the next pregnancy:
- Most doctors recommend waiting at least 12 to 18 months before the next pregnancy
- This gives the uterine scar adequate time to heal and regain strength
- Shorter gaps, under 6 months, are linked to a higher risk of uterine rupture and other complications
- The exact recommended gap can vary based on the individual's healing and any complications from the previous surgery
Who Should Be More Careful?
According to Dr Gupta, certain women need closer attention and monitoring during a pregnancy following a C-section:
- Women who've had more than one C-section
- Those with a shorter gap between pregnancies
- Women with a thin or poorly healed uterine scar, assessed via ultrasound
- Those planning a VBAC, who need closer monitoring during labour
- Women with placenta praevia or accreta in a previous pregnancy
What Other Factors Should You Consider?
According to the NHS Trust, there are extra risks to think about whether you plan a vaginal birth or another C-section. The biggest one talked about is scar rupture. This happens in around 5 out of every 1000 women trying for a vaginal birth after a C-section. Scar rupture can mean the healed wound slowly thins and weakens, called dehiscence, or it can fully break apart.
If you choose a vaginal birth, doctors will closely watch your baby's heart rate through labour. This helps them spot early signs that the scar might be weakening. A repeat C-section carries its own risks too, including heavier bleeding after birth and a higher chance your baby needs extra care.
Dr Gupta highlights a few additional steps worth taking when planning a pregnancy after a C-section:
- Getting an ultrasound assessment of scar thickness before planning the next pregnancy
- Discussing birth plan options, such as repeat C-section versus VBAC, early with the doctor
- Monitoring for signs of scar-related complications throughout pregnancy
- Spacing pregnancies appropriately based on personal recovery rather than just general guidelines
- Considering overall health factors, including age, any pre-existing conditions, and how the previous pregnancy and delivery went
Why Individual Assessment Matters More Than General Guidelines
While the 12 to 18 month recommendation offers a helpful starting point, Dr Gupta's guidance makes clear that individual healing varies quite a bit. Two women with the same time gap since their C-section could have very different scar conditions, which is why an ultrasound assessment before the next pregnancy is such a valuable step. It gives doctors real, measurable information rather than relying on timing alone.

Conclusion
Most pregnant women can have a cesarean section (C-section) and become pregnant safely after the C-section, as long as they follow the guidelines for the period of healing and are closely monitored if there are any particular risk factors. Collaborating with a doctor to evaluate the health of the scar, birth plan options, and appropriate spacing will help maximise the likelihood of a successful next pregnancy.
FAQ
1. Can you have a natural birth after multiple C-sections?
In a few instances, it may be possible. However, the risk is higher with each birth by cesarean section because it is more likely to have complications associated with the scar. A physician would have to thoroughly evaluate the condition of the scars and the woman's pregnancy history before permitting a VBP after multiple cesareans.2. Does a C-section scar cause any long-term discomfort during future pregnancies?
During a later pregnancy, as the uterus expands, some women may experience slight discomfort or pulling around the scar area, especially if they have developed adhesions. This generally can be controlled, but if it remains or increases over time around the scar line, it should be brought to the attention of a doctor immediately.
