PMDD in Its Earliest Signs: What We Missed as Teenagers
I got my period at 13. And not long after that, something shifted.
Not in a way anyone could clearly name, but not subtle either. Something in me felt sharper, more reactive, harder to manage. By 14, my mum was already taking me to the gynecologist, trying to understand what was happening. Because something clearly was. But no one had an answer.
There were weeks where I felt grounded, capable, like I knew who I was. And then there were weeks where everything felt harder. I was more reactive, more emotional, overwhelmed by things I couldn't explain. Then it would pass, and I'd return to myself.
So I did what most teenagers do. I assumed it was just me.
April is PMDD Awareness Month, and every year I come back to the same thought: we're still having this conversation too late.
For many of us, these patterns didn't start in adulthood. They started early. And no one was looking for them.
What I see now, working with women
Years later, after my own experience, and now working closely with women every day, there's a moment I witness over and over again.
A pause. A reflection. And then:
"I think this was already happening when I was a teenager."
Not in a way that would have been easy to label at the time. But in patterns that become obvious in hindsight.
Emotions that felt disproportionate to the situation. Conflict in relationships that seemed to appear from nowhere. A strong urge to withdraw, followed by a quiet return to feeling like themselves again.
This is the piece that so often gets missed because PMDD isn't constant. It follows a rhythm. Symptoms tend to show up in the one to two weeks before a period and ease once bleeding begins.¹ But if no one teaches you to look at your cycle that way, those shifts don't look cyclical. They look personal.
When patterns get mistaken for personality
This is where things quietly start to take a toll.
When you don't understand what's happening, you fill in the gaps with your own explanation.
"I'm too sensitive.”I overreact."I can't handle things like other people can."
I carried that belief for 17 years. And I see it in so many of the women I work with now, capable, thoughtful, self-aware women who spent years trying to fix themselves, without ever being shown that their symptoms followed a pattern.
On average, PMDD can go unrecognized for close to 20 years.² That's two decades of misunderstanding your own experience.
Why this gets missed in teenagers
Teenage years are already a time of emotional intensity. Hormones are shifting, identity is forming, and everything feels heightened. So when PMDD shows up during that time, it blends in.
Mood swings feel expected. Irritability gets brushed off. Overwhelm is normalized.
But PMDD isn't just about emotional ups and downs; it's about timing and intensity. It's the difference between having a hard day and feeling like a completely different person for a predictable window of time each month.
Most teenagers don't have the awareness or the support to track that. They're not being taught to connect their mood, their thoughts, or their reactions to their cycle. The menstrual cycle isn't framed as something to understand. It's something to "deal with."
So these patterns stay invisible.
Research suggests that in women experiencing PMDD, the brain may respond differently to normal hormonal fluctuations in areas linked to emotion and stress.⁴ What a teenager is feeling may be very real, very intense, and very confusing, especially when it comes and goes without explanation.
And when no one names it, it becomes personal.
Something is wrong with me. I need to fix myself.
When in reality, it might be something that simply needs to be understood.
Why earlier awareness matters
PMDD is estimated to affect around 3–8% of women.³ It's not rare. But awareness in younger years is still limited, and part of that gap starts with what we're not taught.
Most teenagers aren't given a real understanding of their menstrual cycle beyond the basics. They're not taught how hormones can influence mood, perception, or emotional regulation. So when emotional intensity shows up, it gets filtered through a familiar narrative, door slamming, tears, irritability, and dismissed as typical teenage behavior.
Because of that, something patterned gets written off as something personal.
PMDD isn't moodiness. It follows a rhythm. But if no one teaches you to look for that rhythm, you don't make the connection. You experience the shift without context. And without a framework to understand what's happening, you default to self-blame.
Earlier awareness doesn't mean labeling every teenager. It means asking better questions:
Is there a pattern to these emotional changes?
Do they show up before the period and ease after?
Do they feel cyclical rather than constant?
Even that level of curiosity can change how someone understands themselves. It can reduce shame, build self-trust, and shorten years of confusion.
What I wish someone had told me
Not a diagnosis. Not a label. Just this:
"This might not be who you are. It might be your cycle."
That one shift, from self-blame to curiosity, can change everything.
Your body isn't working against you. It's communicating. We just weren't taught how to listen yet.
A different starting point
For some women, PMDD brings intrusive thoughts, deep despair, and even suicidal ideation. When it goes unrecognized for years, that risk can grow, not because someone is weak, but because they've been trying to make sense of something incredibly intense without the right framework or support.
Misdiagnosis. Dismissal. Self-blame. Over time, that takes a real toll on how someone sees themselves. For many, it's not just about the symptoms; it's about the identity damage that builds when you believe, for years, that something is fundamentally wrong with you.
This is why earlier awareness matters so much. Not just to reduce confusion, but to protect how someone relates to themselves.
If you're a parent, a caregiver, or simply looking back at your younger self, this is where things can shift. Not through having all the answers, but through paying attention. To patterns. To timing. To shifts that don't feel so random when you zoom out.
Because this is often where the story actually begins.
When we catch it earlier, when we start to name it, even quietly, we can change what comes next.
Less confusion. Less self-blame. More understanding. More self-trust. And in some cases, a real reduction in suffering and risk.
You don't have to spend years figuring yourself out the hard way. You can meet yourself here instead.
And that can change the entire trajectory.
