The Period Chronicles · The Introduction

One real month. Two real voices. The full picture.

A note before we begin

What you are about to read is not a textbook. It is not a wellness program or a content series dressed up in clinical language. It is something much simpler and much rarer than that.

It is a real encounter.

One woman tracked her cycle in real time, day by day, writing down exactly what she felt as she felt it. No editing. No performance. No waiting until she knew how the story ended. And alongside her, a physician read every word and wrote back, explaining the biology behind each moment, what was driving it, and what could help.

That is this. That is all of this.

If you have a neurodivergent brain and you experience PMDD, or if you suspect you do, this series was made for you. Not for a version of you that has it all figured out. For the version of you that is lying on the couch on day 2 wondering why you cannot function, or white-knuckling through the luteal phase hoping nobody notices, or feeling like a completely different person depending on where you are in your cycle and not being able to explain it to anyone.

By the end of this four-phase series you will be able to explain it. To yourself. To your partner. To your doctor. Because the science is clear and it is on your side, and once you see it you cannot unsee it.

Meet Natalie

In her own words

I am a neurodivergent woman living with PMDD. I am also a school counselor, a mom, and someone who has spent years trying to understand why certain weeks of the month felt almost unsurvivable while others made me feel like I could do anything.

I started tracking this cycle because I wanted to find the patterns. I wanted to know my peak days for productivity, creativity, energy, and focus instead of constantly feeling blindsided by my own brain and body. I also had a feeling my PMDD was affecting far more than just my luteal phase.

I knew Dr. Sarah would be adding the science perspective alongside my notes, but I did not realize how validating and eye-opening this process would end up being. I thought I already understood my PMDD.

I want other neurodivergent women with PMDD to experience what this process gave me: the feeling of finally being understood in a way that holds both the neurodivergent piece and the hormonal piece at the same time.

Because that combination is still so rarely talked about.

And that is what this series is really about.

Meet Dr. Sarah

In her own words

When Natalie shared her cycle notes with me, I did not read them as a clinician looking for symptoms to categorize. I read them as someone who has sat across from women like Natalie for years and watched them leave appointments feeling dismissed, undertreated, or handed a diagnosis that did not quite fit.

PMDD in a neurodivergent brain is its own thing. The hormonal fluctuations of the cycle act on a nervous system that is already wired differently. The dopamine system, the serotonin system, the sensory processing pathways — all of it responds more intensely to the hormonal shifts. And yet most of the clinical literature treats these as separate issues.

They are not separate. They are one system and this series treats them that way.

My role in this series is to read Natalie’s experience and translate it into biology without flattening it. To show you that what she felt was not random, not dramatic, and not something she needed to push through. It was her body doing exactly what bodies do, and it deserved a real clinical response.

That is what I am here to give.

How to read this series

This series follows one complete cycle, broken into four phases. Each phase is its own chapter. Each chapter has the same structure so you always know where you are.

In each free chapter you will find:

• Natalie’s journal entries for that phase, exactly as she wrote them

• Dr. Sarah’s clinical response to each entry, explaining the biology and neurochemistry in plain language

• A hormone and neurotransmitter chart showing what her body was doing during those days

• An ND spotlight comparing the neurodivergent experience to the neurotypical one side by side

• What her data told us — the patterns that emerged from that phase

In the paid companion for each phase you will find:

• Dr. Sarah’s full clinical protocol: specific supplements, food, movement, work, and sleep recommendations built from Natalie’s data

• Natalie’s video for that phase, recorded in real time

• Dr. Sarah’s video for that phase, walking through the clinical picture and drawing the hormone curves

The four phases

Phase One · Menstruation · Days 1 to 5 Both estrogen and progesterone are at their lowest. The PMDD storm lifts. The body sheds and begins to rebuild.

Phase Two · Follicular · Days 6 to 13 Estrogen rises. Dopamine climbs. The brain starts to feel like itself again. Often described as the clearest window of the month.

Phase Three · Ovulation · Around days 13 to 14 The LH surge triggers egg release. Estrogen peaks. For Natalie, this is also when the cycle turns.

Phase Four · Luteal · Days 14 to 28 Progesterone rises as estrogen stays low. For ND brains with PMDD, this is the most demanding phase of the cycle.

A word about this particular cycle

Natalie’s cycle this month was unusual in a few ways and that is part of what makes it so interesting to document.

Her luteal phase was milder than she expected. Her day 17 anger, which she describes as a reliable signature of her PMDD, did not arrive on schedule. She was also sick during parts of her menstruation and her luteal phase, which layered an immune response on top of the hormonal picture.

She is currently on sertraline, an SSRI, which may be blunting some of the luteal peaks. And she ovulated on approximately day 13 rather than the textbook day 14, which shifted her entire luteal window.

None of this makes her cycle less useful as a document. It makes it more useful. Because real cycles are not textbook cycles. Real cycles are influenced by illness, medication, stress, sleep, and a hundred other things. Watching how all of those variables interact with the hormonal picture is exactly the kind of information that ND women with PMDD need and rarely get.

Before you begin

From Dr. Sarah

A few things I want you to hold onto as you read through this series.

Your symptoms are real. They have biological drivers that are measurable, predictable, and treatable. The fact that you have not had that explained to you clearly before is a failure of the healthcare system, not a reflection of how real your experience is.

Neurodivergence and PMDD interact. They are not separate conditions running in parallel. The ND nervous system responds to hormonal fluctuations differently — more intensely, with less buffer. Understanding this changes how we approach support and treatment.

Tracking is medicine. The act of paying attention to your cycle, noticing the patterns, naming what you feel and when you feel it, is one of the most powerful clinical tools available to you. Natalie’s notes are proof of that.

You are not too much. You are a neurodivergent woman with a hormone-sensitive nervous system living in a world that was not designed with you in mind. That is not a character flaw. That is a context problem. And context problems have solutions.

From Natalie

I just want you to know that I wrote these notes in real time on hard days.

Days when my brain felt scrambled. Days when I was irrationally irritated by things like knuckle cracking. Days when I was lying on the couch at 5:30pm watching Netflix while my brain kept reminding me of all the things I was supposed to be doing instead.

I wrote them anyway.

Partly because I wanted to remember what these phases actually felt like instead of looking back later with blurry hindsight. But also because somewhere in the back of my mind, I had a feeling other neurodivergent women might recognize themselves in these experiences too.

And if that person is you, I am really glad you are here.

Begin with Phase One · Menstruation Days 1 through 5. Where the PMDD storm clears and the body begins again.
