Chromosomal Miscarriage: Improve Your Chances of Pregnancy
A chromosomal miscarriage might have been explained to you as an unlucky mistake in an embryo's genetic instructions. It's often described as the thing that means you're doomed in the future.
I'm here to tell you that's not necessarily the case. But for me to get there, I need to go through some really important information, so please, don't skip ahead, read on...
Chromosomal development starts before we think about fertility
Did you know, the story of how your chromosomes develop begins decades before you even become pregnant?
And some fascinating new research is revealing just how complicated that process really is. Spoiler alert, I've taken that research and worked with ladies who after multiple chromosomal miscarriages, fell pregnant first time after working with me, and carried full term to have a beautiful and healthy baby.
But before we get to that, understand this first.
In 2026, researchers published a study in Nature analysing genetic data from more than 139,000 IVF embryos.
They were investigating how chromosomes exchange genetic material and separate so that an egg ends up with the correct number.
And they found an important connection between those genetic exchanges and the likelihood of chromosome errors.
Read the 2026 Nature research.
Now, here's the interesting bit.
Your eggs don't simply sit in your ovaries, fully prepared, waiting for a sperm to arrive.
Their chromosomes began pairing up and exchanging genetic material while you were still developing in your own mother's womb.
Some of the connections formed during that process then have to be maintained for decades, until an egg eventually matures and its chromosomes separate.
Think about that for a moment.
A biological process that began before you were born is still playing a part in your fertility today.
And throughout their development, your eggs are surrounded by ovarian cells that communicate with them and help support their growth and maturation.
A 2025 scientific review from the University of Edinburgh explored these relationships, including the importance of cellular energy, oxidative stress, chromosome stability and communication between the egg and its surrounding cells. Bear with me, this is important.
Essentially the science says, there's a lot more going on in egg development than simply how many eggs you have left.
Does this mean we've discovered how to prevent every chromosome error? We're not there yet.
But science is learning an extraordinary amount about the processes involved in egg development, and why some eggs are more likely than others to develop with the correct chromosome number.
Think of the egg like a car: even with good fuel and regular maintenance (cellular energy, healthy communication between ovarian cells and balanced oxidative stress), ageing and wear on its internal parts (chromosome connections) can affect how reliably everything works.
Now, if you've experienced a miscarriage due to chromosomal abnormalities, I imagine you're understandably, less interested in the science for its own sake than in one very important question.
What does all this mean for our chances of having a healthy baby next time?
That's exactly we'll explore together now.
Because understanding what happened to one pregnancy is valuable.
But understanding your wider fertility picture, what may be influencing it and what deserves attention before your next pregnancy?
That's where you can use this conversation to potentially change your future.
What causes chromosomal miscarriage?
Let's start with what probably happened.
Normally, an egg contributes 23 chromosomes and a sperm contributes another 23.
Together, they provide the genetic instructions needed for the embryo to develop.
But sometimes, when chromosomes separate during egg or sperm formation, an error occurs. Like when you're weighing flour for a cake — a little too much or too little can change how it turns out. With chromosomes, an extra or missing copy can affect whether the embryo develops normally.
An embryo might receive an extra chromosome, a missing chromosome or an abnormal arrangement of genetic material. And depending on which chromosomes are affected, normal development may become impossible.
According to the American Society for Reproductive Medicine's 2026 guidance, approximately 50–60% of first-trimester miscarriages are caused by embryonic aneuploidy, meaning an abnormal number of chromosomes.
So if this happened to you, it is one of the most common explanations for early pregnancy loss. I know that doesn't make this easier, but it's easy to feel isolated in this situation, and you are absolutely not.
But I also want to ask you something.
Do you actually know which chromosome abnormality was found?
Because an embryo with an extra chromosome — called a trisomy — isn't necessarily telling us the same story as an embryo with an unbalanced chromosome rearrangement.
One may have arisen through a random error.
The other could, in some circumstances, point towards an inherited genetic rearrangement.
And if your pregnancy tissue wasn't tested, a chromosomal explanation may have been suspected rather than confirmed.
Why does this matter?
Because your previous result can tell us something about the risks that deserve consideration before another pregnancy. And that's the area that I work in - it's much more useful than being left with the explanation that it was simply bad luck.
Can chromosomal abnormalities be prevented?
Here's something I want you to understand about egg development.
Think of chromosomes as instruction manuals moving along a production line. The egg contains the machinery that separates them into the correct sets. If that machinery isn't working properly, an egg can end up with an extra manual or one missing — and that can affect how the embryo develops.
That cell needs energy in order to do its job of separating into the correct sets. Its internal structures must work together. And as the egg grows, it communicates with the surrounding cells that support its development like a factory making Teddy bears. It needs electricity to run, machines that work properly and people helping along the way. If something goes wrong, the finished bear might have a 1 arm, or an extra leg.
Researchers are investigating how those processes change with age and how aspects of cellular function may influence egg development. Now a point here, when we talk about age, we're not talking just about years, we're talking about the health age of a cell, because we can be the same amount of years old as someone next to us, but if I've had masses of oxidative stress for example, and the lady next to be hasn't then her cell will be 'younger'.
And, that's exciting, because it opens up new possibilities for understanding reproductive health. To be honest, this is what I've been doing for years, but it's so exciting now that the scientific research is now catching up.
One chromosomally abnormal embryo doesn't mean all your future embryos will be abnormal.
Every egg is different. It develops in a different environment (or at least we can make that so) it has a different set of stressors affecting it. And it is implanting into a different quality environment too if we do our jobs right.
Think back to our little egg factory. If the machinery has the energy it needs, the production line is running smoothly and the support team (the surrounding ovarian cells) is doing its job, we're giving that egg the conditions it needs to develop.
And if your next egg produces a healthy embryo, wouldn't you also want to make sure your body has everything it needs to support that pregnancy?
We can't change the chromosomes of the baby you've lost. But that doesn't mean your future is set in stone. And that's why looking at your wider fertility health can be so valuable.
Because your next pregnancy is a new pregnancy, and its development involves more than chromosomes alone.
So here's what I'd love you to consider.
Has anyone helped you understand your overall fertility picture, or has the conversation stopped at the chromosome result?
How to avoid chromosomal abnormalities in pregnancy
If you've been searching for how to avoid chromosomal abnormalities in pregnancy, I imagine you're hoping there's something you can do differently next time.
And that makes perfect sense.
I have two separate questions.
Is there anything we need to understand about your risk of producing another chromosomally abnormal embryo.
That involves age, the specific chromosome abnormality and whether there's any reason to investigate an inherited genetic issue.
The second question is just as important for your overall fertility journey.
If you conceive an embryo with the potential to develop normally, is there anything in your health or reproductive history that deserves attention before that pregnancy begins?
Let's look at why I ask that.
Your next pregnancy involves more than the embryo
You now understand why your next pregnancy involve more than the embryo. But here's where the recent research is also exciting (I'm sorry, I get excited when Western science catches up).
Scientists are discovering more about the environment supporting pregnancy
In 2025, researchers published a study in Science Advances examining endometrial biopsies from 924 women.
They were looking at how the uterine lining prepares itself for pregnancy through a process called decidualisation. They discovered patterns of weakened or stalled preparation were associated with a greater risk of recurrent miscarriage. This is HUGE.
Read the 2025 endometrial research.
Now, think about that. If your uterine lining isn't preparing properly, what sort of welcome is a healthy embryo getting? It needs somewhere it can implant, establish a connection with your blood supply and begin developing a placenta. So even when the embryo has the right chromosomes, the environment it arrives in still matters.
But it does show why scientists are investigating the wider reproductive environment instead of looking exclusively at embryo genetics.
And it's incredibly encouraging that there is now science backed data backing up what I've been doing for 16+ years.
We're learning more about how different parts of reproduction work together.
Which brings me back to you.
What if your chromosome result explained what happened to one pregnancy, but other details in your history were still relevant to your next one?
Knowing now about the way that the system interacts, do you think it's likely that the last time was one random chromosome error?
If you've experienced repeated losses, fertility problems or other relevant symptoms, wouldn't you want to know whether those things can be improved at their root cause level?
That's why your history matters so much.
Can you have a successful pregnancy after a chromosomal abnormality?
Yes, absolutely.
And there's a good biological reason to be hopeful.
An error affecting one egg doesn't automatically mean the next egg will have the same error. You see that now.
So a successful pregnancy after a chromosomal abnormality is entirely possible.
In fact, most of my ladies who experience an isolated chromosomal miscarriage go on to have a healthy pregnancy.
But what about your individual chances?
Let's imagine two women.
One is 29. She's conceived naturally, had one miscarriage and testing showed a sporadic trisomy.
The other is 41. She's experienced several miscarriages, has been struggling to conceive and is now considering IVF.
Both have experienced a chromosomal miscarriage.
But would you expect them to have the same chance of a successful pregnancy, or need exactly the same advice?
Of course not.
Their fertility histories and genetic will be different regardless of years on the calendar.
And the questions that deserve answering will be different too.
The first lady may have no reason to undergo additional fertility investigations.
The second may benefit from a structured recurrent miscarriage assessment and a proper discussion of her reproductive options.
So when someone tells you that you'll probably be fine next time, wouldn't you want to understand what that means for you, rather than the average woman? Because an average is pulled from a large scale.
Reassurance is lovely. I get it.
But do you want blind reassurance? Or is understanding your actual circumstances far more useful when you're deciding what to do next?
Age, egg quality and chromosomal abnormalities
Let's return to something we touched on earlier.
Your eggs began developing long before you were born.
And over time, the mechanisms responsible for maintaining chromosome connections and separating chromosomes accurately become more vulnerable to errors.
That's one of the reasons the risk of embryo aneuploidy increases with maternal age.
But egg quantity and the chromosome status of an individual egg are not the same.
Have you ever been told your eggs must be poor quality because your AMH is low?
AMH primarily gives us information about ovarian reserve (the number you have left, not their quality) and thus likely response to ovarian stimulation. It doesn't directly tell us whether an individual egg has the correct number of chromosomes.
A woman with low AMH can still produce a chromosomally normal embryo.
And someone with reassuring AMH can still experience a chromosomal miscarriage.
So if you've been told your egg quality is poor, I want to know what that conclusion was based on.
Was it your age?
Your AMH?
The number of eggs collected during IVF?
Embryo development?
Or actual genetic testing?
Because these results tell us different things. That's what we uncover in the Free Fertility Analysis
What about improving egg quality?
This is where research into cellular health, energy metabolism and the ovarian environment becomes fascinating.
Scientists are exploring how the egg and its surrounding cells work together, and whether particular biological processes could eventually become targets for treatment. Like the factory we mentioned earlier.
What we know is there are sensible things we can do for preconception health, including identifying relevant nutritional deficiencies, reviewing medical conditions and addressing established lifestyle risks. Because your body will be different to someone else's, notice I say relevant, because we need to identify what your body needs. Not generic answers.
Supporting general health isn't the same as reversing the chromosome changes associated with ageing.
We're not asking, "How do I improve my egg quality?" but,
"What do MY actual results suggest, and is there anything RELEVANT that I should be addressing before trying again?"
Especially if time is an important factor in your fertility journey.
If you're preparing for IVF, you may also find my guide to preparing for egg retrieval useful.
What if all my embryos are aneuploid?
If you've been through IVF and every embryo tested has been reported as aneuploid, I imagine the question running through your mind is:
"Does this mean I'll never make a healthy embryo?"
But let's look at what the result actually tells us.
It tells us about the embryos tested in that particular cycle.
And the number of embryos tested makes a considerable difference.
If two embryos were tested and both were abnormal, that's two results.
If you've had 15 embryos tested over several cycles and every one was abnormal, that's a different amount of information.
But all of these were getting themselves all nicely developed in an sub-optimal environment. Until you change that, why would you expect a different result?
That's why, I don't particularly mind if you've had 7 rounds with every single result being a chromosomal abnormality - because nothing had changed in terms of improving the environment. IVF doesn't touch the environment...it just puts egg and sperm together.
So rather than immediately assuming your next cycle will be the same, wouldn't it make sense to see what we can improve?
And if some embryos were reported as mosaic or inconclusive, those findings shouldn't be treated as identical to other aneuploid results.
Think of it like checking a batch of cakes by tasting a tiny piece of each. If some pieces taste right and others don't (mosaic), or the sample doesn't give you a clear answer (inconclusive), you can't assume the whole cake is faulty. That's why these embryos shouldn't then automatically be treated as completely aneuploid.
Balanced translocation, miscarriage and pregnancy
This is a good example of why understanding the exact chromosome abnormality matters.
A balanced translocation happens when parts of chromosomes exchange places without an overall loss or gain of genetic material. Think of swapping two chapters between different instruction manuals. All the information is still there, just in a different place, so everything may work perfectly well — until those instructions need to be divided up to create a new set.
Someone can carry this rearrangement and be perfectly healthy. But when they produce eggs or sperm, that arrangement can sometimes result in embryos receiving too much or too little genetic material.
Which then leads to miscarriage.
Can you have a healthy pregnancy with a balanced translocation?
Yes.
But the chances depend on the specific rearrangement.
Some couples have healthy pregnancies naturally.
Others consider IVF with preimplantation genetic testing for structural rearrangements, known as PGT-SR.
And genetic counselling can help explain the available options.
If your pregnancy involved a structural chromosome abnormality, has anyone explained whether you or your partner should have chromosome testing?
Because that could be a much more relevant next step than simply adding another fertility supplement.
Can you see how understanding the actual finding changes the conversation?
Can IVF prevent chromosomal abnormalities?
IVF allows eggs to be fertilised in a laboratory and embryos to be observed during their early development.
In some circumstances, it also allows genetic testing before an embryo is transferred.
But IVF doesn't correct chromosome errors that occurred in the egg, sperm or developing embryo.
Its potential advantage is that it can provide additional information and reproductive options.
For some couples, particularly those with an inherited chromosome rearrangement or other fertility problems, that may be useful.
But experiencing one sporadic chromosomal miscarriage doesn't automatically mean IVF is necessary.
So if you're considering IVF after a miscarriage, what is the specific problem you're hoping IVF will help you solve?
And has anyone explained why it's likely to be beneficial in your circumstances?
Does PGT-A prevent chromosomal miscarriage?
PGT-A examines sampled cells from IVF embryos to look for abnormalities in chromosome number.
That information can help clinics prioritise embryos reported as euploid — meaning they have the expected number of chromosomes.
And in some IVF settings, this can reduce the risk of miscarriage following embryo transfer.
But there's an important distinction.
Reducing miscarriage risk and improving your overall chance of taking home a baby aren't necessarily the same thing.
The UK's Human Fertilisation and Embryology Authority rates PGT-A positively for reducing miscarriage risk for most fertility patients.
But it rates the treatment negatively for improving the chance of having a baby for most patients.
Why?
Because PGT-A helps select between embryos. It doesn't repair chromosomes, and testing may reduce the number of embryos available for transfer. PGT-A helps your clinic choose which embryos to transfer. It checks a small sample of cells from each embryo for chromosome abnormalities, rather than fixing anything that's wrong.
So why might you end up with fewer embryos to transfer? Because embryos reported as chromosomally abnormal may be ruled out, even though they were previously available for transfer. And because the test only examines a few cells, some results aren't completely clear-cut, particularly with mosaic embryos.
ASRM's 2026 guidance also concludes that PGT-A has not been shown to improve live-birth rates compared with trying to conceive without IVF in the specific setting of recurrent pregnancy loss.
So before agreeing to PGT-A, I'd want to ask your clinic:
"Are we doing this to reduce the chance of another aneuploid embryo transfer, to improve our overall chance of a live birth, or because we want more information about our embryos?"
Because those are different objectives.
Now there is a valid logical argument rather than me just quoting the research, that surely you are at least playing the odds against chromosomal abnormalities? But, if you're doing that, why not, reduce the number of eggs that have a chance of chromosomal abnormalities by improving the environment in which they develop, thus, as we've seen, reducing the risk of these abnormal cells developing the first place?
We've talked a lot about eggs.
But your partner contributes half the embryo's nuclear genetic material.
And his reproductive health is part of the picture too. Some chromosome errors originate from sperm. Either partner can carry an inherited structural chromosome rearrangement.
Research has found associations between elevated sperm DNA fragmentation and recurrent miscarriage. It's a huge thing.
Now, sperm DNA fragmentation isn't the same thing as an embryo having an abnormal number of chromosomes.
And an elevated result doesn't establish that sperm 100% caused a particular miscarriage.
But in selected cases of unexplained recurrent miscarriage or recurrent miscarriage alongside infertility, ASRM's updated guidance says sperm DNA fragmentation testing may be considered.
So if you've experienced repeated miscarriages, has your partner's reproductive health been considered alongside yours?
Because it's important that the fertility conversation involves both of you. It takes two to tango as they say.
Not that every man needs additional specialist testing. But as we're looking at the wider picture, we shouldn't overlook relevant information simply because the woman is the one experiencing the miscarriage.
And if your partner's semen analysis came back normal, there's something else worth understanding. Can sperm cause miscarriage even when his results look fine? Here's what the research says about sperm DNA fragmentation and recurrent pregnancy loss.
What can I do after a miscarriage due to chromosomal abnormalities?
Now, let's bring all of this back to your situation.
Because we've looked at some fascinating research.
We've explored why chromosome errors happen, why one abnormal embryo doesn't predict every future pregnancy, and why other aspects of reproductive health may still matter.
But I'm guessing you're now wondering something.
"How do I know which of these things actually matters for me?"
Knowing that something can affect fertility isn't the same as knowing whether it's affecting yours.
Let me explain.
Imagine two women with the same miscarriage diagnosis
Both have been told that their miscarriage involved a chromosome abnormality.
The first woman has regular cycles, no known medical problems, no previous fertility difficulties and a confirmed sporadic trisomy.
Her history may be reassuring.
She may not need additional fertility investigations beyond discussing her result and receiving appropriate preconception advice.
Now imagine the second woman.
She's experienced several miscarriages. She's had difficulty conceiving. She has unusually heavy bleeding and a history of surgery involving her uterus.
Would you approach those two women in exactly the same way?
I wouldn't.
In the second woman's case, I'd want to know whether the uterine cavity had been assessed, because certain abnormalities can affect future pregnancy outcomes.
That doesn't mean her uterus caused the chromosomal miscarriage.
But her wider history contains additional information that deserves consideration.
And if a relevant problem were found, her specialist might have a treatment or management option worth discussing.
Can you see why looking at the full history is so different from simply responding to a diagnosis?
What if your fertility results were pieces of the same puzzle?
Perhaps you've already had several blood tests.
You've had scans.
Maybe you've been through IVF and have pages of embryo reports.
You've been told one result is normal, another is borderline, something else is nothing to worry about.
But has anyone helped you understand how those results fit together?
For example, if you've been told your thyroid result is normal, was it assessed in the context of your symptoms and medical history?
If you're taking supplements, do you know what each one is meant to address?
If your periods have changed, does your history suggest they need investigating?
If you've had unsuccessful IVF cycles, what actually happened at each stage?
And if you've had recurrent pregnancy loss, have the appropriate medical and genetic investigations been considered?
These are the questions that turn information into something useful.
Because what I see so often is women collecting more and more fertility information without becoming any clearer about what to do.
One person recommends supporting egg quality.
Another talks about inflammation.
Someone else tells you to change your diet, improve your gut health or take another collection of supplements.
And soon you're trying to do absolutely everything.
Doesn't it make more sense to establish what is important for YOU?
That's what I care about.
This is where Fertility Bandwidth™ comes in
My approach starts by looking at your wider fertility picture.
Not just the most recent diagnosis.
I want to understand your history, previous results, but also the clusters of symptoms that your body speaks to us in every day. It's easy to ignore these things because they're not a 'diagnosis' but they are important. Because they're signals of your e.g. nutritional or metabolic health. And that's important for avoiding chromosomal miscarriage.
Perhaps a diagnosed uterine condition, relevant hormonal findings or questions about your previous IVF treatment. It might be that your eyesight tells us something, or how whether you have brittle nails. Seemingly random things are all indicators of how your body is working. And then we can combine it with test results and figure out what on earth is going on under the surface to cause the chromosomal abnormalities you've been struggling with. Once we know that, we can go about setting a robust plan to change that environment for the better.
The point is that your next step should come from your own information, not somebody else's fertility checklist.
That's what I mean by looking at your fertility bandwidth.
I don't assume every system in your body is under pressure. I don't assume anything for that matter. Together we understand whether there are clinically relevant demands on your reproductive health, whether those demands are modifiable and where support might actually be worthwhile.
Think of your body like a house where several things need attention. You wouldn't have the plumber, electrician, builder and decorator all working in the same room at once. It would be chaos!
Instead, you work out what needs attention first, deal with that, and then move on to the next job.
That's how we approach Fertility Bandwidth. We identify your priorities, make manageable changes step by step, and see how your body responds before deciding what comes next — rather than throwing everything at it at once.
There's also an enormous difference between making ten changes in the hope that one might help and understanding why a particular change is relevant to your situation. If you had a car that's running badly, would you replace the battery, tyres, spark plugs and engine just in case one of them was the problem?
What difference does that make for you?
Imagine knowing which questions you should be asking your clinic.
Which results are genuinely reassuring.
Which areas of your health deserve further discussion.
And which things you've been worrying about probably don't deserve any more of your time or money.
Wouldn't that feel like a much more sensible way to approach your next pregnancy?
That's why I created the Free Fertility Analysis.
We look at your fertility circumstances as an individual and recognise which areas of your history and health may deserve closer consideration.
And if you decide you need more individualised support, you'll have a clearer understanding of why and you can do with that information what you choose. You're not tied into anything by taking the free analysis.
START MY FREE FERTILITY ANALYSIS
What should I look at before trying to get pregnant again?
Before you try again, there are a few things I'd really like you to understand.
What does your previous miscarriage tell you?
Do you know which chromosomal abnormality was involved?
Was it confirmed through testing?
Does it appear to have been a random error, or is there a possible inherited risk?
And has anyone explained what that means for another pregnancy?
Is there anything else in your history that deserves attention?
Have you experienced more than one loss?
Have you struggled to conceive or experienced unsuccessful IVF cycles?
Are there diagnosed conditions or relevant symptoms that warrant assessment?
Or does your history suggest that this was an isolated event, with no reason to undertake more investigations?
ASRM defines recurrent pregnancy loss as two or more pregnancy losses and recommends a structured, individual approach.
This can include assessing miscarriage chromosome results and the uterine cavity, with other investigations selected according to the circumstances. But the goal is to find useful answers, not simply perform more tests.
And if you change the environment as we've seen throughout, wouldn't the results of those tests be different too?
What can you usefully do for your health before pregnancy?
This is where sensible preconception care matters.
Adequate nutrition, recommended folic acid, reviewing medication, avoiding smoking and addressing relevant medical conditions are all worthwhile generic suggestions.
If there's a confirmed nutritional deficiency or medical issue, understanding how to manage it may also be important.
And your partner's health belongs in the conversation.
The objective isn't to create the perfect body though. We're trying to identify whether there is what we can improve before your next pregnancy with the aim of this then being a different outcome.
So, what is your actual next step?
Do you need genetic counselling?
A discussion about recurrent miscarriage evaluation?
A closer review of your previous IVF results?
Or is trying again with appropriate preconception care the most sensible option?
If you don't know the answer, wouldn't it be worth improving your internal fertility environment before investing more time, money and emotion in another approach?
Frequently asked questions about chromosomal miscarriage
Can you have a successful pregnancy after a chromosomal miscarriage?
Yes. Many women have healthy pregnancies after a chromosomal miscarriage. The chance of another loss depends on factors including maternal age, the specific chromosome abnormality and previous pregnancy history.
Does a chromosomal miscarriage mean my eggs are poor quality?
Not necessarily. One chromosomally abnormal embryo doesn't establish that every egg is abnormal. Age influences chromosome-error risk, while tests such as AMH provide different information about ovarian reserve.
Can improving the ovarian environment reduce chromosomal abnormalities?
The ovarian environment plays an important role in egg development, and researchers are investigating how cellular function and communication influence egg maturation. However, clinical studies have not established that a particular lifestyle or supplement intervention reliably prevents embryo aneuploidy.
Can you miscarry a chromosomally normal embryo?
Yes. Chromosomally normal embryos can still miscarry. Sometimes another medical or developmental issue is identified, particularly following recurrent loss, while other losses remain unexplained.
What treatment is available for miscarriage due to chromosomal abnormalities?
There isn't one treatment for every chromosomal miscarriage. A sporadic chromosome error may require no specific treatment before another pregnancy. Inherited structural rearrangements may warrant genetic counselling and discussion of reproductive options. Other diagnosed health conditions are assessed and managed separately where relevant.
Fertility Bandwidth advocates for improving the environment in which the eggs develop (and are put back into post IVF) so that you're cutting down your risks.
Read: IVF Preparation
Should I wait three months before trying again?
Not automatically. After an uncomplicated early miscarriage, many women can try again once symptoms have resolved and they feel ready. Individual medical circumstances, complications or planned investigations may change the advice, so discuss timing with your healthcare professional.

Your next pregnancy deserves a clearer picture
Here's what I find so encouraging about where fertility research is heading.
We're learning more about the extraordinary processes involved in egg development, why chromosomes sometimes separate incorrectly and how different parts of the reproductive system contribute to pregnancy.
Some of those discoveries are already helping us understand infertility and miscarriage more scientifically than we've ever been able to in the past.
Others may eventually lead to new ways of testing or treating particular problems.
But right now, there's something really useful we can already do.
We can stop treating one fertility result as though it tells us everything about a woman's chances of having a healthy baby.
If you've already experienced the heartbreak of miscarriage, wouldn't you rather approach your next pregnancy knowing that the decisions you're making are relevant to you?
That's what I want to help you discover.
Not another enormous list of fertility rules.
Not another collection of things to worry about.
A clearer understanding of your own fertility, what deserves your attention and where the right support could make a meaningful difference.
If that sounds like the kind of approach you've been looking for, let's start with your own fertility picture.
