PMDD, business doubt and what to do when your business suddenly feels like a terrible idea

It can start before you've even got out of bed.

You switch off your alarm. Maybe (definitely) hit snooze. Again.

And before your feet have touched the floor, your brain has already started building its case.

What if today is another day like yesterday? And the day before that?

You pick up your phone.

There they are.

Another woman celebrating her elusive £10k month.

Someone else has a waiting list of clients desperate to join whichever offer she's promoting.

Another coach appears to have sold out her latest programme approximately seventeen minutes after announcing it.

And your business?

Nothing.

There's no amount of Flash Dust Magnets that can hide the stagnation.

And suddenly, that doesn't feel like a quiet week in business.

It feels like evidence.

Evidence that you're not good enough.

That everyone else has figured out something you haven't.

That this isn't working.

Maybe the universe is trying to send you a sign.

It felt like this last month too, didn't it?

Maybe this time you should listen.

And then comes the really painful one:

Why would anyone want to buy from me when I can't even practise what I preach?

Before long, you've travelled from:

Sales are quiet.

to:

What if nobody ever buys from me again?

I'm such a failure.

Maybe I should just give up.

The short answer

If you experience PMDD or severe premenstrual symptoms, the days before your period can coincide with significant changes in mood and your ability to function day to day. For some of us, that can affect not only how we work in our businesses, but how we see them.

That doesn't mean every concern you have during your luteal phase is wrong, and neither does it mean every thought needs immediate action.

My approach is to create space between the thought and the decision:

Capture it, check the context, compare it with evidence over time, then choose what deserves action.

Because a thought can feel completely convincing without requiring you to rebuild your website before lunch.

First, what is PMDD?

Premenstrual dysphoric disorder, or PMDD, is a condition that causes severe emotional and physical symptoms before a period.

According to the NHS, symptoms usually begin around one or two weeks before a period and improve within a few days after it starts. They can include depression or hopelessness, anxiety, irritability, feeling overwhelmed or out of control, fatigue, sleep problems and reduced interest in things you normally enjoy.

These symptoms can be intense enough to make working, socialising and maintaining relationships difficult.

That's important, because PMDD isn't simply "feeling a bit moody before your period".

And there's evidence of an impact on work.

One multinational study found that employed women with moderate-to-severe PMS/PMDD had significantly greater work-productivity impairment than women with no perceived symptoms or mild PMS. Participants in the moderate-to-severe group reported an average of 5.6 days per cycle with at least a moderate reduction in productivity or efficiency in daily routine, compared with 1.1 days in the comparison group.

That study wasn't specifically about entrepreneurs, and it grouped moderate-to-severe PMS and PMDD together, so I don't want to pretend it tells us something it doesn't.

But it does demonstrate something important:

Severe premenstrual symptoms can have a meaningful effect on work and functioning.

So what happens when the woman experiencing them is also the person responsible for the business?

PMDD can hit differently when you're self-employed

When you're running your own business, there isn't necessarily somebody else to pick things up when your capacity drops.

You're potentially:

the CEO
the salesperson
the marketing department
the strategist
the service provider
the finance department
customer support
and the person who remembered at 10.47pm that nobody replied to Sandra's email.

If you don't sell, there are no sales.

If you don't follow up, the enquiry goes cold.

If you don't attend the networking event, nobody attends in your place.

If you cancel client work, there can be a direct financial consequence.

If you disappear from your marketing because being visible suddenly feels unbearable, potential clients don't necessarily know why.

And if you're questioning the entire business while all of this is happening, the impact can go far beyond having a few less productive days.

For me, it definitely has.

When business doubt becomes expensive

My experience of PMDD and business hasn't just meant feeling less productive.

It has had real consequences.

I've spent more than I care to admit on coaching, courses, programmes, memberships and self-study PDFs.

You name it, there's a strong probability that I've bought it.

Because in those moments I can genuinely believe that somebody else has the answer I'm missing.

They know how to make this work and I don't.

And in those moments all I needed to do was open PayPal, press a few buttons and somehow their knowledge will transfer directly into my brain through some kind of business success osmosis.

Spoiler:

This is not how PayPal works.

I've completely rewritten my website more times than I can remember.

I've scrapped offers.

I've pivoted my business.

I've cancelled plans.

Ignored messages.

Skipped networking events.

Stopped selling.

Questioned decisions that felt amazing just a few days earlier.

And the comparison?

It can be brutal.

When you're already questioning whether you're good enough, social media provides an almost unlimited supply of people who appear to be doing better than you.

Their launch sold out.

Another £10k month.

Another waiting list.

Another "I wasn't even going to share this but..." followed by something that makes you want to launch your phone into the garden.

Meanwhile, you're looking at your own business thinking:

See? Proof.

And sometimes the urge to make the feeling stop doesn't even look like a business decision.

Maybe a glass of wine will quieten the noise for an hour.

Maybe some new makeup will make me feel better.

Maybe a new dress.

Maybe a bit of late-night online shopping.

I've had to recognise something uncomfortable:

When my perception of myself changes, my behaviour can change with it.

Some of those decisions can still be sitting on my credit card long after the feeling that drove them has gone.

And that's one reason I've become so interested in what happens when PMDD meets entrepreneurship.

Because reduced capacity is one thing, but making expensive, strategic or difficult-to-reverse decisions because your business suddenly looks completely different to you is another.

Does PMDD change the way you think?

This is where I want to be extremely careful.

It would be very easy to turn this into:

"Never trust your luteal brain."

I don't believe that's helpful, and the research doesn't support such a sweeping statement.

A recent systematic review examined cognition and behaviour across the menstrual cycle in people with PMDD. Across the studies reviewed, evidence of changes in objective cognitive performance was limited and inconsistent. Research into cognitive processes and content suggested that negative attentional bias may play an important role in the psychological experience of PMDD.

In normal every day language?

Researchers are studying how PMDD relates to thinking, attention and behaviour.

But there isn't good evidence for me, as a coach, to tell you that you're incapable of thinking rationally during your luteal phase.

And I'm glad.

Because I don't want the answer to PMDD in business to be:

Trust yourself for part of the month and assume you're an unreliable liability for the rest.

That's not self-trust.

A feeling can be real without being the whole story

This distinction has become hugely important to me.

Nobody bought your offer today.

Information.

"Nobody will ever buy this because I'm rubbish at business."

Interpretation.

Someone unsubscribed from your email list.

Information.

"Everyone is sick of hearing from me."

Interpretation.

You posted something and it got three likes.

Information.

"Nobody cares what I have to say and I should stop posting."

Interpretation.

You had a quiet sales week.

Information.

"My entire business model is broken and I need to spend £2997 on somebody else's programme immediately."

VERY expensive interpretation.

Ask me how I know 🤦‍♀️

The goal isn't to suppress the interpretation.

It's to notice that:

Feeling certain about something isn't the same as having evidence for it.

But don't dismiss every luteal thought either

This matters just as much.

I don't want us replacing:

Everything I think is true.

with:

Nothing I think in luteal is true.

Sometimes there might be something underneath the discomfort that genuinely deserves your attention.

Maybe an offer isn't working.

Maybe you're overcommitted.

Maybe your pricing needs reviewing.

Maybe a client relationship isn't right.

Maybe the way you've built the business requires more capacity than you realistically have.

Maybe social media genuinely is draining far more from you than it's giving back.

Maybe you've been ignoring something for weeks and your tolerance for ignoring it has suddenly disappeared.

So I don't think the answer is:

Ignore the thought.

I think it's:

Don't automatically obey the thought. Don't automatically dismiss it either. Investigate it.

And that's where I've started using a different approach.

The Luteal Decision Filter

When a thought arrives that sounds something like:

I should quit.

I need to completely change my niche.

I need to scrap this offer.

I should delete my website.

I need that programme.

I should drop my prices.

This whole thing is embarrassing.

...I don't need to resolve it immediately.

Instead:

1. CAPTURE

Write the thought down exactly as it arrives.

Don't make it more reasonable.

Don't coach yourself out of it.

Just capture it.

"Nobody wants my coaching. I need to change my entire business."

Fine.

There it is.

Now we have something to examine instead of something ricocheting around your brain.

2. CHECK

What happened immediately before the thought?

A quiet sales day?

A difficult client interaction?

A scroll through Instagram?

Someone else's launch?

Exhaustion?

Poor sleep?

An unexpected bill?

A negative comment?

Or seemingly nothing?

If you track your cycle, check where you are in it too.

This isn't about using your cycle to invalidate yourself.

It's context.

3. COMPARE

Now look for evidence across time.

Did you feel the same way two weeks ago?

Has this concern appeared repeatedly across several cycles?

What does your business data say?

Have potential clients genuinely rejected the offer?

Have you tested it properly?

Are people enquiring but not buying?

Or have you posted about it twice, heard nothing and concluded civilisation has delivered its final verdict?

This is where tracking your business alongside your symptoms becomes interesting.

Memory is a terrible spreadsheet.

Patterns are much easier to recognise when they're written down.

4. CHOOSE

Then choose what the thought deserves.

Maybe you discard it.

Maybe you investigate it.

Maybe you run a small test.

Maybe you ask for support.

Maybe you make the change.

The important bit is:

The intensity of the feeling doesn't get to decide the size of the action.

A huge feeling doesn't automatically require a huge business decision.

A £2,997 example

Here's a real one.

A few months ago I saw a programme.

It looked brilliant.

It was about building business assets, evergreen marketing, masterclasses and creating a business less dependent on social media.

It cost £2,997.

And I wanted it.

Badly.

Old me could easily have interpreted that feeling as:

This is what I'm missing.

The person delivering it knows something I don't.

This could finally make my business work.

I NEED to find the money.

Instead, I stopped.

I looked at what I was attracted to.

Was it the programme itself?

Or had it shown me something I wanted to build?

Turns out I wanted the business model.

Assets.

Searchable content.

A proper email ecosystem.

Evergreen ways for women to discover my work.

Less dependence on the bloody algorithm.

Once I separated the thing I wanted from the person selling it, the decision became much easier.

The programme might be excellent.

That doesn't mean I need to buy it.

So instead of spending £2,997, I'm building the assets.

Including this one.

Hello. 👋

Consistency isn't the same as sameness

I wish somebody had told me years ago that running a business with PMDD didn't mean I had to abandon my mental health in favour of an online guru who has "consistency" as their word of the year. Every year.

I thought successful business owners were consistent.

So I tried to be consistent.

Post consistently.

Sell consistently.

Show up consistently.

Network consistently.

Create consistently.

Follow the strategy consistently.

And when I couldn't maintain exactly the same energy, confidence, capacity and visibility throughout the month, I assumed the problem was me.

So I tried another strategy.

Changed another offer.

Rewrote another page.

Tried harder.

And wondered why running my business felt so bloody difficult.

What I'm learning is that sustainable consistency doesn't have to mean doing the same thing, at the same intensity, every single day.

For me, it means understanding my patterns.

Building around them where I can.

Creating safeguards for the days when my perception of myself and my business changes.

Doing some things ahead of time.

Letting some things wait.

And learning that:

A difficult day doesn't always require an immediate business solution.

Sometimes I need to change something.

Sometimes I need more evidence.

Sometimes I need support.

And sometimes I need to leave the website, the offer and the PayPal app the fuck alone until tomorrow.

Build the business before you need the buffer

This is where cycle-aware business planning becomes much more interesting to me than simply assigning particular tasks to particular phases.

It's not:

"You're ovulating! Quick! Film seventeen Reels!"

No thank you.

It's designing a business with enough resilience that everything doesn't collapse when your capacity changes.

That might mean:

• having lower-capacity tasks ready for difficult days;

• creating content ahead of time when writing feels easier;

• building an email list so your entire visibility strategy isn't dependent on showing your face every day;

• having follow-up systems;

• leaving space around launches;

• building financial buffers where possible;

• creating client boundaries;

• having a plan for cancellations;

• tracking patterns in confidence, capacity, selling and decision-making;

• deciding in advance which kinds of decisions deserve a waiting period.

This is the work that absolutely fascinates me.

Not forcing women with PMDD to become better at overriding themselves.

What if I think I have PMDD?

This article isn't a diagnostic tool and business coaching isn't medical treatment.

If you're experiencing severe emotional or physical symptoms before your period, particularly if they're affecting your work, relationships or everyday life, speak to a healthcare professional.

The NHS recommends seeking help if you think you may have PMDD and says keeping a symptom diary for at least two menstrual cycles can be helpful when speaking to your GP.

And PLEASE take severe mental-health symptoms seriously.

Suicidal thoughts can occur with PMDD. If you're experiencing suicidal thoughts or you're concerned about your immediate safety, seek urgent professional help rather than trying to solve it as a productivity or business problem.

Your business can wait.

So, which version of you should you trust?

I don't think the answer is follicular you.

And I don't think the answer is luteal you.

I think the goal is to build enough self-awareness, evidence and safeguards that neither version has to make every decision alone.

Listen to the thought.

Capture it.

Check the context.

Compare it with the evidence.

Then choose what deserves action.

PMDD shouldn't mean giving up on ambition.

It doesn't mean accepting that you'll never build a consistent business.

And it certainly doesn't mean handing over your self-trust to whoever happens to have the best Instagram funnel that week.

It means recognising that your capacity and perception may change, and building a business robust enough to accommodate that reality.

The goal isn't to build a business that requires you to override yourself in order to succeed.

It's to build one that can still work when you don't feel like the version of yourself who built it.

Frequently asked questions

Can PMDD make you want to quit your business or job?

PMDD can cause severe emotional symptoms and can significantly affect everyday functioning, including work. Some people also describe major cyclical changes in how they perceive their work or business.

That doesn't mean every desire to leave a job or business is caused by PMDD. If the same concern keeps returning, it deserves investigation. The aim is not to dismiss the thought because of where you are in your cycle, but to avoid treating urgency as proof.

Can PMDD affect business decisions?

PMDD can significantly affect mood and functioning. Research into cognition and behaviour is developing, but current evidence doesn't justify assuming that every decision made during the luteal phase is irrational.

For significant, expensive or difficult-to-reverse decisions, creating space between the thought and the action can help you look at context and evidence before deciding what to do.

Should I avoid making big decisions during my luteal phase?

I don't use a blanket "never make decisions in luteal" rule.

Instead, I prefer safeguards for major decisions. Capture the thought, check what's happening, compare it with evidence across time and then decide what deserves action.

That's the basis of my Luteal Decision Filter: Capture, Check, Compare, Choose.

How can I run a business with PMDD?

Start with your individual pattern rather than a generic cycle-syncing schedule.

Track where PMDD has the greatest effect on your business. That might be confidence, capacity, selling, visibility, client delivery, decision-making or something else entirely.

Then you can begin building buffers, systems, lower-capacity options and safeguards around the parts of your business that need them most.
