The 90-Day Runway: What to Change Before You Start Trying

You haven't stopped contraception. You haven't told anyone, possibly not even him, not properly. But you've been reading. Late, phone tilted away, the way you read things you're not ready to say out loud. And somewhere in it you found the number ninety.

And now you're lying there doing arithmetic, wondering whether you've already missed it.

You haven't.

Let's take some of the weight out of that number, because it's a more useful idea than it is an urgent one.

Where the number comes from

The version that gets repeated: eggs take about ninety days to mature, so the three months before you conceive shape the egg you eventually release.

That's close enough to sound convincing, and incomplete enough to be worth correcting.

For sperm, ninety days is a genuinely useful number. It takes a little over two months to produce a sperm cell, with further maturation before it is ready for ejaculation. So the sperm involved in a conception three months from now are, quite literally, being made now. That number is real, and almost nobody tells him.

For eggs, the biology is less tidy. Follicle development begins much earlier than three months before ovulation. The final months are an important part of that journey, but they are not the whole story.

So, not a ninety-day egg. Not a deadline. Just a meaningful stretch of a much longer process.

Which is really why the runway is worth having. Three months is long enough to change what's worth changing, and short enough that you'll actually see it through.

Not magic. Just a sensible length of time to work with.

The unglamorous hour

Before the supplements, before any of it, go and see your GP and say you're thinking about a pregnancy in the next few months.

It is the least interesting hour of the whole ninety days and easily one of the most valuable.

Some medications are better changed before rather than after, including a few you'd never suspect. Some conditions are easier to steady now. Some vaccines can't be given once you're pregnant, which makes this the window rather than a nice idea. And your own history, your cycles, your family, anything that's happened before, changes the advice you should be given, sometimes considerably.

Bring every medication and supplement you take, prescription or otherwise. And don't stop a prescribed medicine because you're planning a pregnancy without talking to the person who prescribed it.

That last part is the real reason to go early. Generic advice only gets you so far. Your history is what changes the details.

Before you reach for the prenatal

This is usually the point where someone hands you a list.

Take this. Avoid that. Buy the prenatal. Start now.

Some of that advice is genuinely important. Australian guidance recommends folic acid before conception, and iodine is routinely recommended for women who are pregnant, breastfeeding or planning a pregnancy. Those recommendations exist for good reasons.

But the interesting thing about preconception care is that it isn't actually identical from one woman to the next.

Some women need a higher folic acid dose than the standard recommendation. Some need to think about thyroid function. Some are managing endometriosis, PCOS or a history of pregnancy loss. Some are taking medications that change the conversation entirely.

Which is why the most useful thing you can do isn't necessarily buying a supplement.

It's finding out what applies to you.

The ninety-day runway is valuable because it creates space for that. Space to have the appointment. Space to ask the questions. Space to make changes gradually instead of reacting once a pregnancy test turns positive.

And while there are a handful of nutrients that deserve specific attention, preparation isn't really about chasing a single vitamin. It's about building a pattern you can sustain.

More protein. More variety. More plants. More meals that look recognisably like food.

Not because perfection improves fertility. Because nourishment tends to work best when it becomes ordinary.

That's the layer we've always cared about.

Fertile Femme was never designed to replace medical advice, folic acid or any recommendation your healthcare team gives you. It's simply a way of making wholefood nourishment easier during the months before conception, the period where most women are trying to prepare well but still have jobs, commutes, children, deadlines and ordinary lives.

The runway isn't about finding the perfect supplement.

It's about arriving at pregnancy already looking after yourself.

The month worth front-loading

Do these early and the rest of the runway is easier.

Alcohol is the first. Australian guidance is that women planning a pregnancy don't drink. Not a moral position. Simply that no safe level has been established and pregnancy is often not recognised immediately.

Smoking and vaping are worth addressing early too, for both of you.

Coffee can stay. Once pregnancy is possible, think in milligrams rather than cups and keep total caffeine below 200 mg a day.

The rest is embarrassingly ordinary.

Sleep, while there's still no baby to blame.

Move your body regularly. Very high training loads combined with not eating enough can disrupt menstrual function, so the goal isn't to stop exercising. It's to do an amount you can properly fuel.

And see the dentist, which nobody thinks of and which is easier now than it will be in eight months.

His ninety days

If there's a man in this, the ninety days apply to him more literally than they do to you.

Repeated or prolonged heat exposure to the testes can affect sperm production. Think frequent very hot baths, spas or regular high-heat exposure.

Smoking matters. Alcohol matters. Weight and metabolic health matter. Some medications matter a great deal and are worth a conversation.

And if you do end up needing a fertility assessment, his side of the equation should be looked at from the beginning too.

Male factors contribute to a substantial share of fertility difficulties. A semen analysis is one of the standard first-line tests when fertility is being investigated, and his GP can organise it.

The point isn't to test every man before a couple starts trying.

It's not to spend a year investigating only one half of the couple.

What we'd put on your plate

Once the recommendations and appointments are handled, the rest is unglamorous and entirely within reach: eat enough, eat real food, and eat in a way you can actually maintain.

Protein regularly through the day.

A genuinely wide range of plants rather than the same four vegetables on rotation.

Iron-rich foods alongside foods containing vitamin C, because vitamin C helps your body absorb non-haem iron.

Fats from whole sources. Nuts, seeds, olive oil.

And enough food overall to support what you're asking your body to do, because chronic under-eating, particularly alongside heavy training, can disrupt ovulation.

Wholefood is where we've put our attention. Not as an ideology, but because food brings fibre, a complex food matrix and a broad mix of nutrients together.

Fertile Femme lives in that layer. Kale, spirulina, beetroot, baobab, acai, pumpkin seed, flax, sunflower, quinoa, lucuma and more. A food-based blend made to keep nourishment simple across ninety days when you are also, presumably, going to work.

What it isn't is a substitute for medical advice, folic acid or iodine where they're recommended.

Those are specific nutrients at specific doses doing specific jobs.

Fertile Femme is the food underneath them.

What you're allowed to ignore

The runway attracts noise. Some of it you can put down.

Detoxes and cleanses, for one. Your liver and kidneys already have that job, and restricting food before conception is precisely backwards.

Every plastic in the house, for another. Reasonable to reduce where it's easy; not worth giving it the enormous share of your attention it tends to demand.

The belief that you've already left it too late.

Starting today beats starting next month, and next month beats not starting.

The window isn't a deadline.

And the idea that you have to be perfect for ninety consecutive days.

Nobody is.

Seventy per cent for three months will serve you better than immaculate for nine days and abandoned by the second week.

When to ask for more

The usual Australian guidance is to see your GP after twelve months of trying if you're 35 or younger, or after six months if you're 36 or older.

Go sooner if your cycles are irregular or absent, or if you already know about something that may affect fertility, such as endometriosis.

Previous pregnancy losses, reproductive surgery, known male-factor concerns or other medical history may also change when your doctor recommends investigating.

Asking early isn't giving up on doing this naturally.

It's just information, and information tends to help.

The runway is the point

Here's what the ninety days really give you.

They give you something to do before the part where you can only wait.

The trying itself is largely out of your hands, and that is the part women find hardest. Not the effort. The powerlessness.

The runway isn't like that.

You can book the appointment. You can ask the questions. You can eat properly, sleep more, stop drinking, and get him to look after his side of the equation too.

None of it is a promise, and anyone offering you a promise is selling you something.

But it's yours to do.

And for now, that's enough.
