PMS and Hormonal Imbalance: How Do You Know Which One You Have?

Quick Answer: How Do You Know If It’s PMS or a Hormonal Imbalance?

Start with timing.

If your symptoms predictably appear after ovulation or in the days before your period and improve once menstruation begins, that pattern is much more characteristic of PMS or PMDD. (Office on Women's Health)

If symptoms happen throughout the month, your periods have become irregular or absent, you have persistent hair, weight, fertility, thyroid-like or metabolic changes, or something about your cycle has clearly changed, I want to look deeper.

And sometimes?

You can have both.

That is why I don't start with the label.

I start with the pattern.

If you missed it, start with Part 1: PMS vs Hormonal Imbalance: What’s the Difference?

“Carola, I Know Something Is Wrong With My Hormones.”

I hear some version of this all the time.

A woman comes to me and says:

“I know my hormones are off.”

She might be bloated.

Her breasts hurt.

She's exhausted.

She can't stop eating sugar before her period.

She cries over something that normally wouldn't bother her.

She's snapping at her husband.

She's suddenly anxious.

Her period is heavier.

Maybe she's passing clots.

Maybe she feels amazing for two weeks and then doesn't recognize herself for the other two.

And she wants to know:

Is this PMS?

Is this a hormonal imbalance?

Is my estrogen high?

Is my progesterone low?

Is it my thyroid?

Do I need hormone testing?

This is where I think women deserve more than a symptom checklist from the internet.

Because I don't start by telling her:

“Your estrogen is too high.”

I don't automatically tell her:

“You have low progesterone.”

And I definitely don't order every hormone test available just because she says she feels hormonal.

I start with her cycle.

The First Thing I Want to Know: When Do You Stop Feeling Like Yourself?

This question tells me so much.

Not:

“Do you have anxiety?”

But:

“When does the anxiety begin?”

Not:

“Are you bloated?”

But:

“When does the bloating appear?”

Not:

“Are you irritable?”

But:

“Are you irritable all month, or does something change after ovulation?”

Imagine this pattern:

You feel pretty good during the first half of the month.

Then something shifts.

Your appetite increases.

You want sugar.

Your breasts get sore.

You feel swollen.

You're more sensitive.

Your patience gets shorter.

A few days before your period, it peaks.

Then your period comes.

And within a day or two you think:

There I am.

That timing matters enormously.

Now imagine something completely different.

You're exhausted every day.

Your hair has been falling out for six months.

You're freezing when everyone else is comfortable.

Your periods are suddenly 45 days apart.

Or you've stopped getting them.

You're gaining weight without understanding why.

You don't feel better when your period arrives.

That makes me think beyond classic PMS.

Same woman.

Some overlapping symptoms.

Completely different pattern.

That is why timing comes before guessing.

PMS and Hormonal Imbalance: What Your Pattern May Be Telling Us

If you notice...	It makes me want to ask about...
Symptoms consistently appear before your period	PMS or PMDD pattern
Symptoms improve shortly after bleeding begins	Premenstrual pattern
You feel relatively well during the rest of the month	PMS/PMDD becomes more likely
Symptoms persist throughout the entire month	Broader investigation
Periods have become irregular or disappear	Ovulation, pregnancy, thyroid, PCOS, perimenopause or other causes
Acne plus irregular cycles and increased facial/body hair	Androgen excess/PCOS evaluation
Persistent fatigue, hair changes or temperature intolerance	Thyroid, iron and other possible contributors
Suddenly much worse PMS in your late 30s or 40s	Perimenopause may be part of the picture
Very heavy bleeding or significant clots	Bleeding deserves proper medical evaluation
Severe depression, anxiety, rage or hopelessness before your period	PMDD needs to be considered
Symptoms began after stopping birth control, pregnancy or breastfeeding	A major hormonal transition may be relevant

This table does not diagnose you.

It tells us where to ask the next question.

That distinction is important.

The 8 Questions I Ask Before I Order Hormone Testing

If you were sitting across from me, these are the things I would want to understand first.

1. When Do Your Symptoms Start?

Three days before your period?

Seven days?

Ten?

Two weeks?

Or are they there every single day?

This is probably the most important question in this entire article.

Because PMS is fundamentally cyclical.

2. What Happens When Your Period Arrives?

Do you feel relief?

Does the anxiety disappear?

Does your mood suddenly lift?

Does your appetite normalize?

Do you feel like yourself again?

That sudden return can be an enormous clue.

I have spoken with women who tell me:

“The minute my period comes, I feel sane again.”

I pay attention to that.

3. Are Your Periods Predictable?

A reasonably predictable menstrual pattern gives us different information from:

• Skipped periods

• Increasingly long cycles

• Very short cycles

• Months without menstruation

• Cycles that have suddenly become unpredictable

If the cycle itself is changing, I don't want to call everything PMS and stop there.

4. Are You Ovulating?

This is where progesterone becomes interesting.

Progesterone rises after ovulation.

So when somebody tells me:

“You have low progesterone,”

one of my first thoughts is:

Did she ovulate?

Because if we don't understand ovulation, we're already trying to interpret progesterone without half the story.

5. What Does Your Bleeding Look Like?

I want to know:

How many days?

Light?

Heavy?

Flooding?

Spotting?

Clots?

Has it changed?

Are you becoming weak or dizzy?

Have you become iron deficient?

I do not believe women should have to become menstrual detectives every time they stand up from a chair.

I did that for years.

Checking seats.

Checking clothes.

Planning what I could wear.

Knowing where the bathroom was.

Carrying enormous pads.

Passing clots.

Bleeding for eight days.

Eventually you can become so accustomed to something that you stop asking whether it should be happening.

Familiar does not automatically mean normal.

And heavy bleeding is not something I would casually reduce to:

“That's estrogen dominance.”

There are multiple possible causes of abnormal bleeding, and it deserves proper evaluation. (CDC)

6. What Happens Outside the Premenstrual Window?

This is one of the easiest ways to prevent ourselves from blaming everything on PMS.

Are you losing hair throughout the month?

Freezing all the time?

Exhausted every day?

Having persistent acne?

Growing new facial hair?

Experiencing fertility problems?

Having heart palpitations?

Feeling anxious every day rather than only before menstruation?

Those symptoms may make me widen the investigation.

7. What Changed?

I love this question.

Because bodies don't exist in a vacuum.

Did you:

• Stop birth control?

• Start birth control?

• Have a baby?

• Stop breastfeeding?

• Enter your late 30s or 40s?

• Begin a new medication?

• Experience prolonged stress?

• Stop sleeping?

• Lose or gain significant weight?

• Dramatically change your exercise or diet?

Sometimes the timeline gives us an enormous clue.

8. How Severe Is This?

There is a very big difference between:

“I'm slightly more emotional before my period.”

and:

“For five days every month I become someone I do not recognize.”

If premenstrual mood symptoms are severe enough to disrupt work, parenting, relationships or your ability to function, I don't want that dismissed as:

“Everyone gets PMS.”

PMDD deserves to be considered.

And if you experience suicidal thoughts or feel that you may harm yourself, that requires urgent professional support.

---

So Do You Actually Need Hormone Testing?

Not necessarily.

This surprises women.

Especially in functional medicine, where it can sometimes feel like the answer to every symptom is:

Order more labs.

I love laboratory testing.

I use it.

But a test should answer a question.

Not simply produce twenty-five numbers for us to stare at.

If your symptoms show a beautifully clear premenstrual pattern, one of the most valuable things you can do first may cost almost nothing:

Track them.

For two or three menstrual cycles, write down:

• Cycle day

• Bleeding

• Flow

• Clots

• Mood

• Anxiety

• Irritability

• Depression

• Energy

• Sleep

• Cravings

• Appetite

• Bloating

• Breast tenderness

• Headaches

• Acne

• Pelvic pain

• Cervical mucus

• Libido

Now instead of saying:

“My hormones are crazy.”

you can say:

“My symptoms consistently begin around eight days before my period, become severe three days before bleeding and disappear by Day 2.”

That is useful information.

---

Can You Have Horrible PMS Even If Your Hormone Tests Are Normal?

Yes.

And I want women to understand this because normal laboratory results can make you feel incredibly dismissed.

PMS and PMDD are not simply diagnosed by finding one hormone that is dramatically too high or too low.

Hormones naturally change throughout the menstrual cycle.

Your brain and nervous system also respond to those hormonal transitions.

So it is possible to experience severe cyclical symptoms even when a routine hormone result falls within a laboratory reference range.

That does not mean:

“Nothing is wrong.”

And it does not mean:

“It's all in your head.”

It means one laboratory number may not answer the question you're asking.

---

How Do I Know If My PMS Is From Low Progesterone?

You don't know from symptoms alone.

This is one of those answers that is less exciting than an Instagram infographic, but much more useful.

Breast tenderness does not prove low progesterone.

Anxiety doesn't prove low progesterone.

Bloating doesn't prove low progesterone.

Irritability doesn't prove low progesterone.

Those symptoms might make us curious about your cycle and ovulation.

But curiosity is different from diagnosis.

And this brings us back to something I wish more women were told:

Progesterone has to be interpreted in relation to ovulation.

---

Why I Don't Blindly Test Every Woman's Progesterone on Day 21

You've probably heard:

“Test your progesterone on Day 21.”

But Day 21 isn't a magical hormonal window for every woman.

Progesterone rises after ovulation.

So if one woman ovulates around Day 14 and another around Day 21, testing both women on the exact same cycle day is not capturing the same biological moment.

The question I care about is not:

“Is it Day 21?”

It is:

“When did you ovulate?”

That is the context I want before interpreting progesterone.

---

Is PMS Always Estrogen Dominance?

No.

This is another place I want to be careful.

In functional medicine, the term estrogen dominance is often used to describe an environment in which estrogenic activity is relatively high compared with progesterone.

But PMS does not automatically equal estrogen dominance.

And symptoms such as:

• Breast tenderness

• Bloating

• Heavy periods

• Headaches

• Mood changes

• Clots

do not prove it by themselves.

I want women to understand estrogen and progesterone.

I just don't want them frightened into believing every symptom means one hormone has gone rogue.

---

When I Want More Information, I Often Use DUTCH Testing

Now we get to testing.

When I want a broader functional look at hormone metabolism, one of my preferred tools is DUTCH — Dried Urine Test for Comprehensive Hormones.

Instead of relying only on one blood collection at one moment, DUTCH uses dried urine samples collected at home.

Depending on the panel, it can give us information about:

• Estrogen metabolites

• Progesterone metabolites

• Androgen metabolites

• DHEA-related markers

• Cortisol and cortisone

• Certain patterns of hormone metabolism

This is one reason I personally like urine testing.

Sometimes I don't only want to ask:

“How much hormone is circulating?”

I may also want additional information about:

“What metabolites are we seeing after the body processes these hormones?”

That gives me another layer of information.

---

Is DUTCH or Blood Testing Better for Hormonal Imbalance?

Neither test is “better” for every woman.

They answer different questions.

And this is important because I don't believe functional medicine and conventional medicine need to fight each other.

If I want appropriate thyroid testing?

Blood.

If I'm investigating specific conventional endocrine abnormalities?

Serum testing may be exactly what we need.

If I want a broader view of reproductive hormone metabolites and hormone metabolism?

That is a situation where I may choose DUTCH.

Sometimes I want one.

Sometimes the other.

Sometimes both.

I use the test that answers the question.

Not the one that's trendiest.

---

DUTCH vs Blood Hormone Testing

Blood Testing	DUTCH Dried Urine Testing
Measures circulating hormone concentrations	Measures urinary hormones and hormone metabolites
Important for many conventional endocrine evaluations	Gives additional information about hormone metabolism
Often captures one collection point	Certain panels use multiple collections
Commonly used for thyroid and many standard endocrine investigations	Can examine estrogen, progesterone and androgen metabolites
May be exactly the right test for the clinical question	May complement rather than replace serum testing

And I want to make something very clear:

DUTCH does not diagnose PMS.

DUTCH does not diagnose PMDD.

And I would never tell a woman she needs DUTCH simply because she has a bad period.

---

When I Would NOT Spend Your Money on a DUTCH Test

I actually think this is just as important as telling you when I use it.

I love having data.

But I don't believe in ordering an expensive hormone panel because:

You're bloated.

You had one terrible cycle.

You're cranky before your period.

Or TikTok convinced you that estrogen is ruining your life.

If you came to me with an extremely clear PMS pattern and had never tracked your cycle properly, I might want that information first.

If you're experiencing very heavy abnormal bleeding, I don't want DUTCH to distract us from investigating the bleeding appropriately.

If your symptoms sound thyroid-related, I want appropriate thyroid evaluation.

If you may have PCOS, infertility, amenorrhea or another endocrine or gynecological condition, you may need different testing.

Testing should clarify the picture.

Not distract us from it.

---

Can You Test Your Hormones While You're on Birth Control?

You can perform laboratory testing while using hormonal contraception, but reproductive hormone results need to be interpreted in that context.

Hormonal contraceptives alter the natural ovarian cycle and, depending on the method, may suppress ovulation.

So if I'm trying to understand your natural estrogen, progesterone and ovulation pattern, I absolutely need to know:

Are you taking hormonal birth control?

A hormone number without that context can tell a very incomplete story.

---

What If You Just Had a Baby or You're Breastfeeding?

Another completely different hormonal context.

After pregnancy, and especially during breastfeeding:

• Prolactin physiology changes

• Ovulation may be delayed or inconsistent

• Your period may not have returned

• Cycles may initially behave differently

• Sleep can be profoundly disrupted

• Your body is still moving through a major reproductive transition

That doesn't mean every symptom should be brushed away with:

“You're postpartum.”

But it does mean I don't interpret your hormones as if nothing has happened.

Context matters.

Always.

---

Why Did My PMS Suddenly Get Worse in My Late 30s or 40s?

One possibility is perimenopause.

And this can be incredibly confusing because women often expect menopause to mean:

My period stops.

But the transition can begin long before the final menstrual period.

Ovulation can become less predictable. (Office on Women's Health)

Cycle length can change.

Hormonal patterns can become more variable.

And suddenly the woman who had manageable periods for twenty years says:

“I don't know what happened to me.”

She may experience:

• Worse PMS

• Sleep disruption

• New anxiety

• Heavier or lighter periods

• Shorter or longer cycles

• Migraines

• Breast tenderness

• Changes in mood

• Changes in bleeding

So sometimes the question isn't:

“Why did I suddenly get PMS?”

It's:

“Am I entering a new hormonal stage?”

---

How Can I Tell PMS From Thyroid Symptoms?

One clue is again:

Timing.

PMS typically follows the menstrual cycle.

Thyroid dysfunction doesn't generally turn itself on seven days before your period and disappear on Day 2.

If you have persistent:

• Fatigue

• Hair changes

• Weight changes

• Temperature intolerance

• Bowel changes

• Heart-rate changes

• Menstrual changes

throughout the month, thyroid evaluation may be appropriate. (NIDDK)

This is exactly why I don't want every woman's symptoms labeled:

“Female hormones.”

Your endocrine system is bigger than your ovaries.

---

What About PCOS?

PCOS can affect ovulation and menstrual regularity and may involve androgen and metabolic changes. (Office on Women's Health)

Things that may prompt a closer look include:

• Irregular or absent cycles

• Signs of inconsistent ovulation

• Increased facial/body hair

• Persistent acne

• Fertility difficulty

• Certain metabolic changes

But having acne before your period does not automatically mean PCOS.

Once again:

Pattern before label.

---

What If My Emotional Symptoms Are Extreme?

This is where we need to talk about PMDD.

If you experience severe:

• Depression

• Anxiety

• Rage

• Irritability

• Hopelessness

• Emotional sensitivity

• Relationship disruption

• Difficulty functioning

during the premenstrual part of your cycle, and symptoms improve once menstruation begins, PMDD needs to be considered.

There is not one blood test that simply says:

PMDD positive. (Office on Women's Health)

The cyclical symptom pattern matters enormously.

And severe emotional symptoms deserve proper care.

Especially if you experience suicidal thoughts.

That is not something I want any woman trying to fix by herself with a supplement stack.

---

So How Do You Know If You Have PMS or a Hormonal Imbalance?

Here's how I would simplify the entire article:

If your symptoms switch on before your period and switch off once it begins:

Think premenstrual pattern.

If symptoms persist throughout the month:

Look broader.

If your periods are becoming irregular or disappearing:

Look broader.

If ovulation appears inconsistent:

Look broader.

If you're having heavy or abnormal bleeding:

Investigate the bleeding.

If you have hair, weight, metabolic, fertility or thyroid-like changes:

Look beyond PMS.

If your premenstrual emotional symptoms are severe:

Consider PMDD.

If you're in your late 30s or 40s and everything suddenly changed:

Think about perimenopause.

And if the story still doesn't make sense?

That is when targeted testing can become incredibly useful.

---

Before Your Next Appointment, Do This

For the next two or three cycles, keep a simple record.

You don't need a beautiful journal.

Your phone notes are enough.

Write down:

Cycle Day

Mood

Anxiety

Energy

Sleep

Cravings

Bloating

Breast tenderness

Headaches

Pain

Bleeding

Clots

Cervical mucus or other signs of ovulation

Then look backward.

Not just:

How bad did I feel?

Ask:

When did it start?

When did it peak?

When did it stop?

That pattern may tell us more than you expect.

---

What I Want Women to Stop Doing

I want women to stop thinking they have to choose between:

“It's just PMS.”

and:

“My hormones are completely broken.”

There is an enormous amount of space between those two statements.

You can have significant PMS.

You can be highly sensitive to the hormonal transitions of your menstrual cycle.

You can have a separate endocrine or gynecological condition.

You can be entering perimenopause.

You can have PMDD.

You can have more than one thing happening at the same time.

Your body does not care what label fits neatly into an Instagram square.

And neither do I.

I want the pattern that explains the woman.

---

Why This Became So Personal for Me

If you read Part 1, you already know that I did not arrive at this subject because hormones sounded interesting.

I arrived here because I lived it.

For years I believed terrible periods were simply part of being a woman.

Eventually I stopped asking:

“What can I take for this symptom?”

and started asking:

“Why is my body struggling so much every month?”

That question took me into herbal medicine, functional nutrition, endocrine health, the nervous system and the menstrual cycle.

And eventually it became part of why I formulated Hormone & PMS Support™.

Not because I believe one formula can diagnose or correct every hormonal condition.

It cannot.

And not because every woman has the exact same “imbalance.”

She doesn't.

I created it because I wanted a comprehensive botanical and nutritional formula designed to support menstrual and hormonal health rather than treating the menstrual cycle like a collection of unrelated symptoms.*

My dream behind it has always been simple:

What if your period came…

and you barely noticed it?

Not because your body stopped cycling.

Because your period stopped running your life.

---

Frequently Asked Questions About PMS and Hormonal Imbalance

Can PMS be caused by a hormonal imbalance?

PMS and hormonal imbalance can overlap, but PMS does not automatically mean hormone levels are abnormal. PMS can occur in response to the normal hormonal changes of the menstrual cycle.

How do I know if I have PMS or a hormonal problem?

Look first at symptom timing. Symptoms that predictably appear before menstruation and improve shortly after it begins fit a premenstrual pattern. Persistent symptoms, significant cycle changes or other endocrine signs warrant a broader evaluation.

Can hormone tests be normal even if my PMS is severe?

Yes. PMS and PMDD are not diagnosed simply by finding an abnormal estrogen or progesterone result. Symptom timing and severity remain important.

Does low progesterone always cause PMS?

No. Symptoms alone cannot establish low progesterone, and progesterone needs to be interpreted in relation to ovulation.

Does heavy bleeding mean estrogen dominance?

No. Hormonal patterns may affect bleeding, but heavy menstrual bleeding has multiple possible causes and should be evaluated appropriately.

Is DUTCH better than blood hormone testing?

Not universally. DUTCH provides urinary hormone and metabolite information, while serum testing is appropriate for many conventional endocrine questions. I choose testing based on the clinical question I'm trying to answer.

Is there a blood test for PMDD?

There is no single blood test that diagnoses PMDD. The timing, severity and cyclical pattern of symptoms are central to its evaluation.

---

PMS and Hormonal Imbalance: The Bottom Line

If Part 1 taught you the difference between PMS and hormonal imbalance, I want Part 2 to leave you with something more useful:

A way to think.

Don't start with:

“Which hormone is broken?”

Start with:

When do I feel different?

When do I feel better?

What is my cycle doing?

Am I ovulating?

What does my bleeding look like?

Are these symptoms cyclical or constant?

What changed?

And what question would testing actually answer?

That is how I approach hormones.

Not as random numbers.

Not as one isolated symptom.

Not as one villain hormone.

As a story.

Your menstrual cycle is giving you information every month.

The goal is to learn how to read it.

TO YOUR INVISIBLE BATTLES AND UNSEEN STRENGTH.
