PMS or PMDD? Premenstrual Symptom Identifier
A private quiz that reads your premenstrual symptoms — which ones, when in your cycle, how severe, and how much they get in the way — to tell whether they look like ordinary PMS or the more severe, mood-dominated pattern of premenstrual dysphoric disorder (PMDD). It's a starting point, not a diagnosis, and nothing you enter leaves your device.
This reads your symptom pattern — it's a starting point, not a diagnosis. PMDD is confirmed only by daily tracking over a couple of cycles or by a clinician. If you're having thoughts of harming yourself, call or text 988 now.

Premenstrual mood changes can bring these thoughts, and they are a treatable symptom — not a character flaw. Telling someone is the strongest next move.
This reads your symptom pattern from memory — it's a starting point, not a diagnosis. PMDD is confirmed only by prospective daily symptom charting over at least two cycles, or by a clinician. Only a clinician can diagnose PMDD, PMS, or another condition after talking with you.

PMS, PMDD, and the thing that separates them
Almost everyone who menstruates gets some premenstrual symptoms — bloating, tender breasts, irritability, low mood, cravings — in the days before a period, easing once it starts. That's PMS, and for most people it's a bothersome-but-manageable part of the cycle.
PMDD — premenstrual dysphoric disorder — is the smaller, more severe end of that same spectrum. What sets it apart is that it's mood-dominated: it takes at least one marked mood symptom (irritability or anger, depression or hopelessness, anxiety or tension, or marked mood swings), five or more symptoms in total, and — the part that matters most — clear interference with work, relationships, or daily life. It's uncommon, real, and treatable.
The single most important clue is timing. Both PMS and PMDD live in the week or two before the period and fade within a few days after it starts, with a symptom-free stretch in the week that follows. Symptoms that run all month long, or that arrive during or after the period, aren't this pattern — they point toward something else, like depression, anxiety, or a condition that simply flares premenstrually. This tool reads for that timing first.
Side by side
PMS vs. PMDD, at a glance
A quick map of how the two compare — same premenstrual timing, different severity, focus, and what it takes to confirm each. The criteria here paraphrase the recognized DSM-5 definition of PMDD alongside ACOG and Office on Women's Health guidance.
| PMS | PMDD | |
|---|---|---|
| How common | Very common — most people who menstruate get some symptoms | Uncommon — affects a small share (roughly 1 in 20 or fewer) |
| Timing | Days before the period, easing once it starts | The week or two before, easing within a few days after it starts, minimal the week after |
| Main symptoms | A mix of physical and emotional changes, often mild-to-moderate | Mood-dominated: marked irritability, depression, anxiety, or mood swings, plus others |
| Symptom count | Any number; no formal threshold | Five or more symptoms, including at least one marked mood symptom |
| Effect on life | Bothersome but usually manageable | Clear interference with work, relationships, or daily life |
| How it's confirmed | Clinical picture; no daily charting needed | Prospective daily symptom charting over at least two cycles |
These are typical distinctions, not a scoring rule — and where you fall can move from cycle to cycle. Only prospective daily tracking or a clinician can tell PMS and PMDD apart with confidence.
How PMDD is confirmed
A quiz can start the conversation — daily tracking confirms it
This is the part no questionnaire can shortcut. PMDD is confirmed by prospective daily symptom charting across at least two menstrual cycles — not by a one-time recall of how things have felt. Here's what that looks like and why it matters.
Rate symptoms every day
Each day, note your main symptoms — mood, irritability, anxiety, energy, physical symptoms — and mark the days of your period. A paper calendar, a notes app, or a period-tracking app all work; clinicians often use a structured diary called the Daily Record of Severity of Problems.
Over at least two cycles
One cycle can mislead. Tracking across two or more shows whether the pattern repeats, which is what the criteria require.
Look for the cyclical fingerprint
PMDD symptoms build before the period, drop within a few days of it starting, and are minimal the week after. If your symptoms are there all month, that points somewhere else.
Bring it to a clinician
A record of real days saves time and gives a clinician exactly what they need to sort out PMDD, PMS, or another cause — and to tailor treatment.
Whatever this tool suggests, the next step is the same: track it, then talk with a clinician. That's how a pattern becomes an answer.
When to get help
When to reach out — and when it's urgent
Any thoughts of self-harm
If you ever have thoughts of harming yourself or that you'd be better off dead — premenstrually or at any time — reach out now. Call or text 988 (Suicide & Crisis Lifeline), free and 24/7. In immediate danger, call 911. This doesn't wait for a score or an appointment.
Mood symptoms running your life
Premenstrual irritability, anxiety, or depression that disrupts your relationships, work, or daily life is worth a clinician's attention — that level of interference is exactly what separates PMDD from ordinary PMS.
Symptoms that don't fit the pattern
If low mood, anxiety, or irritability are there most of the month rather than just before your period, that points away from PMS and PMDD and toward something a clinician should evaluate directly.
You just want an answer
You don't have to be sure it's PMDD to ask for help. If the pattern is distressing, that alone is reason enough to start tracking and talk with a clinician.

Where this comes from
The distinction this tool reads — cyclical, premenstrual timing that eases after the period; at least one marked mood symptom; five or more symptoms in total; and clear interference with daily life — paraphrases the recognized DSM-5 criteria for PMDD (no copyrighted text is reproduced) alongside ACOG's and the Office on Women's Health's patient guidance on PMS and PMDD, and MedlinePlus. The confirmation standard — prospective daily symptom charting over at least two cycles — and the crisis resource (988 Suicide & Crisis Lifeline) follow that same guidance. We don't diagnose; we read a pattern and point toward tracking and a clinician.

Good to Know
PMS, PMDD & telling them apart: frequently asked questions
How PMS and PMDD differ, how this tool reads the pattern, why a quiz can't diagnose PMDD, how to track your symptoms, how PMDD is treated, and how private this is.
What's the difference between PMS and PMDD?
Both are premenstrual — the symptoms show up before a period and settle once it starts — but they differ in severity and focus. PMS (premenstrual syndrome) is the very common mix of physical and emotional changes most people who menstruate feel to some degree, and it's usually manageable. PMDD (premenstrual dysphoric disorder) is the smaller, more severe end of the same spectrum: it's mood-dominated, with at least one marked mood symptom like irritability, depression, anxiety, or mood swings, five or more symptoms in total, and clear interference with work, relationships, or daily life. Think of it as a difference of degree and impact rather than two unrelated things — and where someone falls can shift from cycle to cycle, which is why tracking matters.
How does this tool decide PMS versus PMDD?
It paraphrases the recognized criteria for PMDD (from the DSM-5) alongside ACOG and Office on Women's Health guidance. It asks four things: when your symptoms happen relative to your period, which mood symptoms you get, which other symptoms come along, and how much they interfere with your life. To point toward PMDD, the pattern has to be clearly cyclical (before the period, easing after), include at least one marked mood symptom, reach five or more symptoms in total, and clearly disrupt daily life. If it's cyclical but milder, that reads as PMS; if the symptoms aren't clearly tied to your cycle, that points somewhere else worth checking. It's a pattern read from your memory, not a diagnosis.
Can this tool diagnose PMDD?
No — and no single questionnaire can. PMDD is confirmed by prospective daily symptom charting across at least two menstrual cycles: rating your symptoms each day so the cyclical pattern (or its absence) shows up clearly. Clinicians often use a structured daily diary for this, such as the Daily Record of Severity of Problems. A one-time quiz like this reads a snapshot from memory, which is a useful starting point for a conversation but can't confirm or rule out PMDD on its own. Treat a result here as a reason to start tracking and to talk with a clinician, never as a diagnosis.
How do I track my symptoms to confirm the pattern?
Keep a short daily rating of your main symptoms — mood, irritability, anxiety, energy, physical symptoms — through at least two full cycles, noting the days of your period each time. What you're looking for is the cyclical fingerprint: symptoms that build in the week or two before your period, drop off within a few days of it starting, and are minimal in the week after. If that pattern is clear and the mood symptoms are marked and disruptive, that supports PMDD; if the symptoms are there all month, that points to something else. A paper calendar, a notes app, or a period-tracking app all work — and bringing that record to a clinician saves time and gives them exactly what they need.
How is PMDD treated, and when should I see a clinician?
PMDD is treatable, and the options differ somewhat from everyday PMS care. A clinician might discuss certain antidepressants (SSRIs, sometimes taken only in the premenstrual phase), hormonal approaches like specific birth control pills, and lifestyle and stress measures — tailored to you. See a clinician if premenstrual mood symptoms are disrupting your relationships, work, or daily life; if they're getting worse; if you're weighing whether it's PMDD, depression, or something else; and always promptly if you ever have thoughts of harming yourself. You don't need to be certain it's PMDD to ask for help — the pattern being distressing is reason enough.
