Trying to Conceive After a Caesarean

A caesarean does not make you less fertile

Start here, because it worries people unnecessarily. Having had a caesarean does not damage your ovaries, and it does not usually affect your tubes. Your ability to conceive is essentially unchanged. Any difficulty conceiving after a caesarean is far more likely to relate to your age, your cycles, or the same factors that affect anyone.

What a caesarean does affect is the next pregnancy and birth, and that is where planning pays off.

How long to wait

The scar in your uterus — not the one you can see, the one in the muscle beneath — needs time to heal and regain strength before it carries another pregnancy and, potentially, labour. This is the main reason a longer interval is advised after a caesarean than after an uncomplicated vaginal birth.

The interval also directly affects your birth options. A short gap between a caesarean and the next birth is one of the factors that can make a planned vaginal birth after caesarean less likely to be recommended. If a VBAC matters to you, the spacing decision and the birth decision are linked, and worth discussing together.

Your own recommended interval depends on why you had the caesarean, whether the wound healed well, whether you had an infection, and your age. Ask for it rather than adopting a number from the internet.

Your birth options next time

You should be offered a genuine choice and a proper discussion of both routes.

Planned vaginal birth after caesarean (VBAC)

Most people who have had one caesarean with a standard low transverse incision are candidates. The majority who attempt it give birth vaginally. The principal risk that shapes the conversation is scar rupture, which is uncommon but serious, and is why VBAC is recommended in a unit with immediate access to emergency caesarean and continuous monitoring in labour.

Planned repeat caesarean

Predictable and scheduled, with the trade-offs of major abdominal surgery: longer recovery, and increased risks in any subsequent pregnancies. Recovery with a toddler already at home is a real practical consideration that is often underweighted.

The RCOG's patient information on birth after previous caesarean sets out both in detail. Your individual chance of a successful VBAC depends on why you had the first caesarean, whether you have ever given birth vaginally, and how this pregnancy progresses.

The placenta issue, which is the real reason to plan

Each caesarean increases the chance in later pregnancies that the placenta implants low in the uterus (placenta praevia) or grows abnormally deeply into the scar (placenta accreta spectrum). The RCOG covers both in its patient information on placenta praevia, placenta accreta and vasa praevia.

These conditions are uncommon, but they are serious, and the risk rises with each additional caesarean. This matters most for people planning larger families. The practical implications are straightforward:

• Tell your midwife at booking that you have had a caesarean, and how many.
• Expect a scan to check the position of the placenta.
• If the placenta is low or lies over the scar, you will be monitored more closely and your birth planned carefully in advance.

This is a reason for good antenatal care, not a reason to avoid another pregnancy.

Before you conceive

• Ask for your notes or a debrief from the last birth if you do not know exactly what happened and why.
• Get scar pain, numbness or an overhang assessed if it is bothering you.
• Rebuild core and pelvic floor strength — abdominal surgery plus pregnancy is a substantial hit.
• Check iron levels if you bled heavily.
• Start folic acid before trying, on advice appropriate to you.
• If the birth was traumatic, address that before the next pregnancy rather than during it.

Scar problems that can affect conception

Uncommonly, a caesarean scar heals with a small defect or pouch in the uterine wall. This can cause prolonged brown bleeding after periods and, in some cases, is associated with difficulty conceiving. If you have persistent post-period spotting since your caesarean, mention it — it is investigable and treatable, and it is easily dismissed as unimportant if you do not raise it specifically.

When to seek advice

See your GP before trying if you had a classical (vertical) uterine incision, more than two caesareans, a wound infection or complicated healing, a very short interval since surgery, or if you are unsure what type of incision you had. And see them if you have been trying for a year, or six months if you are over 35, as you would after any birth.

How many caesareans is too many

There is no fixed maximum, and this is one of the most common questions asked. What is true is that risks accumulate with each one — adhesions inside the abdomen, and the placenta problems described above. Surgery becomes progressively more difficult where there is scar tissue from previous operations.

This is a discussion to have with an obstetrician who knows your history, ideally before conceiving, rather than a number to look up. For most people planning two or three children it is not a limiting factor.

If your last caesarean was an emergency

The reason for the first caesarean strongly predicts what happens next time. A caesarean for a one-off situation — a breech baby, a placenta praevia, fetal distress in that particular labour — has different implications from one for a labour that did not progress. Knowing which category you are in changes the conversation about a vaginal birth next time, and it is the first thing to establish at a debrief.

Scar recovery worth attending to first

• Numbness around the scar is normal and often improves slowly over a year or more.
• Scar massage, once fully healed, can help with tethering and sensitivity.
• An overhang where tissue sits over the scar is common and can trap moisture; keep it clean and dry.
• Persistent pain, tenderness or a pulling sensation beyond a few months should be assessed rather than accepted.
