Having preeclampsia in a previous pregnancy changes how you approach the next one. It is natural to feel a mix of hope and apprehension when you see a positive test, or even when you are still at the planning stage. What happened before stays with you, and it is completely reasonable to want answers before you find yourself back in unfamiliar territory.

The good news is that a previous diagnosis is not a verdict. It is information, and in pregnancy care, information is one of the most useful things you can have.

This fact sheet is for women who have been through preeclampsia before and explains what a subsequent pregnancy might look like. It covers the conversations to have before you conceive, through to the monitoring and management involved.

What is my actual risk of pre-eclampsia happening again?

Recurrence is possible, but it is not inevitable. Research consistently shows that the majority of women who experienced preeclampsia in a previous pregnancy do not develop it again. That said, a prior history remains one of the strongest individual risk factors, and your risk is meaningfully higher than that of someone with no history of the condition.

How high that risk is depends on several factors, including how severe your previous preeclampsia was, how early in the pregnancy it developed, whether it was early-onset (before 34 weeks) or late-onset, and whether any underlying health conditions contributed. Women who had severe or early-onset preeclampsia generally carry a higher recurrence risk than those who developed a milder form later in pregnancy.

This variation is exactly why individual risk assessment matters more than population averages. Your situation is specific to you, and understanding your personal risk profile is the foundation of good planning.

“A previous diagnosis of preeclampsia tells us something important about how your body responded to pregnancy. It is not a prediction of what will happen next time, but it is information we take seriously from the very first appointment.” — Teresa Clapham, Chief Sonographer, QUFW

Before you conceive: conversations worth having

One of the most valuable things you can do is speak with your GP or obstetrician before you start trying to conceive. This is not always top of mind, but it can make a real difference to how your next pregnancy is managed.

The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) recommends that women with a history of preeclampsia be reviewed prior to a subsequent pregnancy to identify and address modifiable risk factors. This pre-conception conversation is a chance to revisit what happened in your previous pregnancy, identify any underlying conditions that may have contributed (such as hypertension, kidney disease, diabetes, or autoimmune conditions), and explore whether anything can be optimised before you fall pregnant again.

For some women, this means getting a chronic condition better controlled. For others, it may simply mean having an early referral pathway in place so that care begins promptly from the moment a pregnancy is confirmed. Either way, starting that conversation early puts you in a stronger position.

How does risk screening differ in my next pregnancy?

The first trimester combined screening for preeclampsia, typically performed at your 13 to 14 week scan, still applies in a subsequent pregnancy and remains a valuable tool. What changes is the weight your history carries within that screening.

A prior history of preeclampsia is factored into the risk calculation alongside your blood pressure readings, blood test markers (including PAPP-A and PlGF), and uterine artery Doppler measurements. Because your previous experience is already a significant risk factor, you may be more likely to receive a high-risk result than someone without that history. This is not the screening working against you. It is the screening working as intended, by accounting for your full picture rather than treating you as a first-time case.

It is also worth understanding that a high-risk result is not a diagnosis. Many women who screen as high-risk go on to have healthy pregnancies without developing preeclampsia. The purpose of early screening is to personalise your care and enable timely intervention where it is needed.

“When a woman comes to us having had preeclampsia before, the 13-week scan carries extra meaning. We are not starting from zero. Her history shapes every measurement we take and every result we interpret.” — Teresa Clapham, Chief Sonographer, QUFW

Is Aspirin suitable for preeclampsia?

If you have a prior history of preeclampsia, low-dose aspirin will very likely be recommended as a preventative measure in your next pregnancy. For women who have been through preeclampsia before, the reasoning behind this recommendation often lands differently. You already know what it is trying to prevent.

RANZCOG and the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) both support the use of low-dose aspirin for women at increased risk of preeclampsia. The recommended dose is 100 to 150mg taken at night, commenced before 16 weeks of pregnancy and continued until 34 to 36 weeks gestation.

Evidence shows that starting aspirin before 16 weeks can reduce the risk of early-onset preeclampsia by up to 62 to 82%, depending on the study. It will not eliminate risk entirely, but it is one of the most effective tools currently available.

Aspirin is considered safe in pregnancy for most women, but always confirm with your treating doctor before commencing, particularly if your circumstances have changed since your last pregnancy, or if you have any known allergies or medical contraindications.

What does a preeclampsia monitoring plan might look like?

Women with a prior history of preeclampsia are typically managed as higher-risk from the outset of a new pregnancy. In practical terms, this means your care will likely include more touchpoints than a standard low-risk pregnancy.

You can expect some or all of the following, depending on your individual circumstances and your treating team’s recommendations: earlier referral to an obstetrician or maternal-fetal medicine specialist, regular blood pressure monitoring throughout the pregnancy, urine testing for protein at antenatal appointments, blood tests to monitor kidney and liver function, additional growth scans in the second and third trimester to assess your baby’s development, and placental function assessment, including Doppler studies, particularly if growth concerns arise.

“More monitoring can feel overwhelming, especially when you are already carrying anxiety from a previous pregnancy. But I always remind women that what we are doing is watching closely so that we can act early. That is a genuinely protective thing.” — Teresa Clapham, Chief Sonographer, QUFW

This level of monitoring can feel intensive, and it is worth acknowledging that more appointments and more testing can themselves become a source of stress. It helps to reframe closer monitoring not as a sign that something is already wrong, but as a deliberate strategy to catch any changes early, when options are broader and outcomes are generally better.

What happens if I get preeclampsia again?

For some women, preeclampsia will develop again despite best efforts at prevention and monitoring. If that happens, earlier detection usually means more options and a more managed response.

Having been through it before, you are also better equipped than most. You are more likely to recognise early symptoms, more likely to know when to escalate a concern, and more likely to have a care team who is already prepared and monitoring closely. None of that eliminates the difficulty, but it does change the experience in meaningful ways.

SOMANZ guidance emphasises that women with recurrent preeclampsia benefit from specialist involvement early in pregnancy, and that a clearly documented management plan, established before symptoms develop, leads to better outcomes for both mother and baby.

“Women who have had preeclampsia before often come in with better questions, sharper instincts, and a clearer sense of when something feels off. That experience, as hard as it was to go through, genuinely matters in the next pregnancy.” — Teresa Clapham, Chief Sonographer, QUFW
