How Long Should You Keep Trying When Your Fertility Tests Are Normal After 35?

By Erica Hoke, Certified Naturopathic Coach (IPHM)

Your fertility testing came back normal.

Your tubes are open.

You're ovulating.

Maybe your AMH doesn't look alarming. Your partner's semen analysis was reassuring.

And yet month after month, you're still not pregnant.

So now you're left with a question that sounds simple but really isn't:

How long should I keep trying?

If you're over 35, “just give it more time” can feel especially painful.

Because time does matter.

But that doesn't mean every woman with normal fertility testing should immediately move to IVF, either.

The real question isn't simply:

How many more months should I try?

It's:

Do I have enough information to know whether continuing the same approach still makes sense?

That's a very different question.

The Short Answer: Six Months Is a Trigger for Evaluation, Not an Expiration Date

For women 35 and older, current fertility guidelines recommend beginning an infertility evaluation after about six months of regular unprotected intercourse without pregnancy. For women over 40, evaluation and treatment may be appropriate even sooner.

That six-month point does not mean:

You only have six months to get pregnant.
Natural conception is suddenly impossible.
You automatically need IVF.
Something catastrophic happens on your 35th birthday.
You should spend those six months doing nothing except waiting.

In fact, you don't need a reproductive endocrinologist to begin getting a clearer picture of your health.

Your primary-care physician or OB-GYN can often review basic health testing such as a CBC, thyroid function and other routine labs based on your medical history. Your OB-GYN may also be able to begin parts of a fertility evaluation or order appropriate reproductive hormone testing before you ever reach an REI.

And if you already know you have irregular cycles, endometriosis, previous pelvic surgery, recurrent pregnancy loss, male-factor concerns or another condition associated with infertility, you don't necessarily need to wait six months before asking for an evaluation.

The six-month guideline means your age changes the value of time.

Instead of continuing indefinitely without understanding what may be happening, it is reasonable to begin gathering information earlier.

And once your fertility evaluation is complete, the next decision should be based on much more than the calendar.

If Everything Is Normal, Why Not Just Keep Trying?

Sometimes continuing to try naturally is completely reasonable.

But there is an important difference between:

continuing to try with an intentional plan

and

continuing to do exactly the same thing because nobody knows what else to tell you.

If a standard fertility evaluation has not identified a cause, you may receive a diagnosis of unexplained infertility.

That doesn't mean your infertility isn't real.

It means standard testing has not identified a clear explanation.

ASRM estimates that up to 30% of couples experiencing infertility may receive this diagnosis after a standard evaluation.

That's where I think women deserve a much better conversation than:

“Everything looks good. Keep trying.”

Five Questions I Would Ask Before Giving It Another Six Months

When I work with a woman who has been told everything looks normal, I don't start by telling her to stop trying naturally.

I also don't immediately hand her another giant testing list.

I start here.

1. Was Your Fertility Evaluation Actually Complete?

Women often use the phrase “I've had everything tested,” but when we look through their records, “everything” can mean very different things.

A standard fertility evaluation generally considers:

Your reproductive and medical history
Menstrual and ovulatory patterns
Uterine and pelvic anatomy
Whether the fallopian tubes are open
Male reproductive history and semen analysis
Ovarian reserve when clinically appropriate

Both partners should generally be evaluated at the same time when a male partner is contributing to conception.

That sounds obvious.

In practice, I still see women who have undergone months of evaluation while the male side received considerably less attention.

Or women who assume a particular part of their reproductive health was investigated simply because they were seeing a fertility specialist.

Before deciding to simply keep trying, I want to know:

What was actually evaluated?

Not just:

“Did somebody tell you everything was normal?”

2. Has Anyone Looked at Your Broader Preconception Health?

This is one of the biggest gaps I see in my coaching practice.

Women often assume that because they're seeing a reproductive endocrinologist, someone is also thoroughly reviewing every aspect of their overall health in preparation for conception and pregnancy.

Those are not necessarily the same job.

A reproductive endocrinologist is appropriately focused on reproductive medicine.

I'm also interested in another layer:

What does the rest of this woman's health picture look like?

Depending on her history and symptoms, I may want to know whether basic health information such as the following has even been reviewed:

CBC
Ferritin and iron status when appropriate
Thyroid function
Vitamin D when deficiency is suspected or documented
B12 and folate when diet, gastrointestinal history or other factors make them relevant
Metabolic health when there is a reason to evaluate it
Previous nutritional deficiencies
Medication history
Gastrointestinal or absorption concerns
Menstrual blood loss
Dietary restrictions

This is not because every one of these results has to reach some magical “fertility optimal” number.

And it is not because a low nutrient level automatically explains infertility.

It's because preparing for pregnancy involves a whole person—not just ovaries, tubes and sperm.

For example, iron requirements increase significantly during pregnancy, and iron depletion can exist before frank anemia appears on a CBC.

Likewise, women with known thyroid disease have specific preconception and pregnancy-management considerations.

That doesn't make either issue “the hidden cause of infertility.”

It means they deserve appropriate attention.

And this is an important distinction:

Your REI may have done an entirely appropriate fertility workup.

You may still have aspects of your broader preconception health that no one has meaningfully reviewed.

Those two things can both be true.

3. How Long Have You Actually Been Trying?

Six months means something different when you're 35 than when you're 41.

And six months of trying means something different from three years of trying.

Female fertility declines with age.

That doesn't mean age should become the explanation for every fertility problem.

I don't think it's helpful when a woman's entire story gets reduced to:

“You're older.”

But I also don't think it's responsible to pretend age doesn't matter.

When I'm thinking about how much additional time makes sense, I want to know:

Your current age
How long you've already been trying
Whether you've ever conceived
Whether there have been pregnancy losses
Whether fertility treatment has already been attempted
How your ovarian reserve has been interpreted
Whether there is a known diagnosis
What your partner's evaluation shows
Whether there are symptoms or medical-history clues that deserve attention

The question is not:

“Is 38 too old to keep trying naturally?”

The better question is:

“Given this particular 38-year-old woman's history, what would we hope to accomplish by continuing the same plan for another six months?”

If nobody can answer that, I don't think “keep trying” is much of a strategy.

4. Is There Something in Your History That Changes the Conversation?

This is another reason I don't believe in one fertility checklist for everyone.

A woman with predictable cycles, no pelvic symptoms, no history of pregnancy loss and a reassuring partner evaluation presents differently from a woman with:

Significant pelvic pain
Known or suspected endometriosis
Heavy menstrual bleeding
Irregular cycles
Thyroid disease
Previous pelvic surgery
Recurrent miscarriage
Repeated failed embryo transfers
Male-factor findings
Gastrointestinal or absorption problems
Previously documented nutrient deficiencies

Those details don't automatically diagnose anything.

But they can tell us where a more targeted question may be appropriate.

This is what I mean when I talk about individualized investigation.

I'm not looking for an excuse to test everything.

I'm looking for a reason to ask the right next question.

5. What Would Change Your Decision?

This is probably the most important question.

Imagine you decide:

“I'll keep trying naturally for another six months.”

Okay.

What happens at the end of those six months?

Do you:

Start IUI?
Consider IVF?
Seek a second opinion?
Repeat the same testing?
Investigate a specific concern?
Keep trying another six months?
Work on an identified health issue first?

If there is no defined point at which the strategy changes, “trying a little longer” can quietly become another year.

That is especially important after 35.

You don't need to make every fertility decision today.

But you do need to know what information or milestone would cause you to reconsider the plan.

When Does Continuing to Try Naturally Make Sense?

There isn't one answer that applies to every woman.

Continuing to try may be reasonable when:

Your fertility evaluation has been appropriately completed
You understand what has and has not been assessed
There isn't an urgent medical reason to move more quickly
You and your partner understand your age-related considerations
You have discussed your options with your medical team
You have decided on a defined period of time rather than indefinite waiting
You know what your next step will be if pregnancy doesn't happen

There is a world of difference between:

“I'm giving myself another three months because I understand my situation and I'm comfortable with that decision.”

and

“They told me everything was normal, so I guess I'll just keep trying.”

The first is a decision.

The second is limbo.

When Should You Reconsider “Just Keep Trying”?

I would be especially reluctant to rely on indefinite expectant management when:

You're over 35 and have already been trying for a significant period
You're over 40
Your history contains symptoms or diagnoses that may need further evaluation
You've experienced recurrent pregnancy loss
There are unresolved male-factor concerns
You've already experienced fertility-treatment failures
Parts of the original evaluation were never completed
You have significant health issues that deserve management before pregnancy
Your emotional wellbeing is deteriorating because every month feels like another round of waiting without direction

This doesn't automatically mean IVF is the answer.

It means the plan deserves another conversation.

What Does Medical Treatment Look Like for Unexplained Infertility?

For couples who truly meet the criteria for unexplained infertility, ASRM's treatment guideline generally supports an initial course of three or four cycles of ovarian stimulation with oral medication plus IUI, followed by IVF for those who are unsuccessful, although individual treatment decisions depend on age and clinical circumstances.

That is one evidence-based medical treatment pathway.

But knowing the guideline still doesn't answer every personal question.

You may still want to understand:

Whether your workup was complete
Whether your partner's evaluation deserves another look
Whether there are health issues worth addressing alongside treatment
Whether you're comfortable with the proposed timeline
Whether another medical opinion makes sense
Whether you're emotionally and practically ready for the next treatment step

Understanding those questions doesn't mean rejecting fertility treatment.

It means making an informed decision about it.

This Is Where I Think Fertility Coaching Should Be Different

I don't believe my job is to convince every woman that her doctor missed something.

I also don't believe my job is to convince every woman to avoid IVF.

And I definitely don't think my job is to give every client the same list of 30 laboratory tests.

My job is to help you see your fertility story as a whole.

When a client tells me:

“Everything was normal,”

I want to understand:

What was actually tested
What each result was designed to tell us
What her history looks like
What her partner's evaluation shows
What her broader health and nutritional picture looks like
Whether anything deserves appropriate medical follow-up
What has already been tried
What questions remain unanswered
And—most importantly—what information would actually change her next decision

Sometimes I see an obvious gap.

Sometimes I see something in the general health picture that deserves attention from her physician.

Sometimes I conclude that her fertility evaluation really was quite comprehensive.

All three answers are valuable.

Because we're not looking for a reason to keep testing.

We're looking for clarity.

The Question Isn't “How Long Can I Keep Trying?”

Biologically, you can continue trying.

That's not really what you're asking.

You're asking:

“At what point does continuing without changing anything stop being the best choice?”

And after 35, I think that deserves an actual answer.

Not fear.

Not pressure.

Not a promise that some hidden lab will solve everything.

And not another vague:

“Give it time.”

Your next step should be based on your age, your history, your completed evaluation, your partner's evaluation, your broader health picture and what you would actually do differently with more information.

That's a plan.

Still Not Sure Whether You Should Keep Trying or Change Course?

If your fertility testing looks normal but you're still not pregnant, you don't necessarily need another huge testing list.

You may need someone to help you identify what is already known, what is genuinely unanswered and what deserves your attention next.

Quick Answers

How long should I try to get pregnant after 35 before seeing a fertility specialist?

Professional fertility guidelines recommend evaluation after approximately six months of regular unprotected intercourse without pregnancy for women 35 and older. Women over 40 may warrant more immediate evaluation.

You don't have to wait until that point to schedule a preconception visit with your OB-GYN or primary-care provider, especially if you have health concerns, irregular cycles or known fertility risk factors.

If all my fertility tests are normal, should I just keep trying?

Not automatically. Normal testing may result in a diagnosis of unexplained infertility. Your age, total time trying, completeness of the evaluation, your partner's evaluation, reproductive history and treatment goals should all help determine whether continued trying, further evaluation or treatment makes sense.

Can I have unexplained infertility even if all my tests look normal?

Yes. Unexplained infertility refers to infertility in which a standard evaluation has not identified a clear cause.

Does a normal fertility workup mean my overall health is optimized for pregnancy?

No. A standard infertility evaluation is primarily designed to assess reproductive factors such as ovulation, anatomy, tubal patency and semen, with additional evaluation guided by medical history.

It is not necessarily the same thing as a comprehensive preventive or preconception health assessment.

Should I have CBC, ferritin, thyroid, vitamin D and B12 checked?

If it has been more than a year since you've had a preventive or well-woman visit, I would start there.

Current women's preventive-health recommendations call for at least one preventive-care visit each year, and pregnancy planning is an especially good reason to make sure your routine health care is current.

That does not mean every woman needs CBC, ferritin, thyroid, vitamin D and B12 tested every year.

It means your primary-care physician or OB-GYN should have an opportunity to review your general health, medical history, medications, diet, menstrual history, previous laboratory results and pregnancy plans and decide which testing makes sense for you.

For a woman trying to conceive, I would particularly want to know whether there is a reason to review things such as:

CBC
Iron/ferritin
Thyroid
Vitamin D
B12/folate
Metabolic health

The reason might be something as simple as heavy periods, fatigue, a restrictive diet, thyroid history, gastrointestinal problems or a previously documented deficiency.

You don't need every test. But you should not assume your REI's fertility workup replaced your annual physical and broader preconception-health review.

Does trying naturally longer hurt my chances of IVF later?

You were born with the lifetime supply of eggs you will have, and reproductive potential changes with age. Delaying treatment therefore carries different implications at 36 than at 41.

That doesn't mean every month of natural trying is a mistake.

It means the decision should be made intentionally with your age, ovarian reserve, reproductive history, length of time trying and treatment options in mind.
