A practical daily diary for premenstrual mood changes, including timing, symptom-free days, daily-life impact, and questions for a clinician.
If your mood changes seem linked to your menstrual cycle, record symptoms daily across the whole cycle, including days when you feel well. Note period dates, emotional and physical symptoms, and how they affect everyday life. Bring the record to a clinician. A diary can support assessment for premenstrual dysphoric disorder (PMDD); it cannot diagnose it on its own.
What matters most
The NHS describes PMDD as severe emotional and physical symptoms before a period. A clinician needs to understand both the symptoms and their timing. An especially difficult Tuesday, or an app's predicted period date, cannot provide that picture alone.
The NHS suggests a symptom diary for at least two menstrual cycles. That is a useful record to bring, not a waiting period before you are allowed to ask for help. Book an appointment while you track if your symptoms are affecting you.
Write on days that feel ordinary too. If you only log the hardest days, the record cannot show whether symptoms ease at other points. If your periods are irregular or absent, record actual dates and tell your clinician; do not force your experience into an assumed 28-day cycle.
PMDD means premenstrual dysphoric disorder. The concern is a recurring pattern of significant symptoms around the menstrual cycle with meaningful disruption to daily life. The NHS describes emotional symptoms such as marked irritability, anxiety, low mood, and mood changes, alongside physical symptoms. A symptom list alone cannot establish the diagnosis; timing, severity, impact, and alternative explanations all matter.
The Royal College of Obstetricians and Gynaecologists recommends recording symptoms across at least two consecutive cycles. Write down the easier stretch as carefully as the difficult one. A record of relief can be as informative as a record of distress. This is not a request to endure severe symptoms without help while gathering evidence.
That phrase is too simple. A controlled study of ovarian suppression and hormone add-back found that changes in hormone levels, rather than continuously elevated levels, triggered symptoms in a selected group with PMDD. It helps explain why sensitivity to change is studied. It does not mean a consumer hormone test can confirm PMDD, or that you should manipulate hormones yourself.
Those possibilities can overlap in how they feel, and a clinician should assess them. ACOG explains that other conditions can resemble PMS or worsen around menstruation. That is one reason a whole-cycle diary is more useful than a collection of bad-day notes.
You do not have to decide which label fits before the appointment. “I have anxiety throughout the month, but it feels much worse before bleeding starts” gives useful information without making a diagnosis. So does “I feel substantially better during part of the month.”
Do not use the following template as a PMDD test. It has no diagnostic cutoff. If your clinician recommends a standardized daily rating instrument, use that instrument and its instructions rather than substituting your own score.
Premenstrual exacerbation, often shortened to PME, describes an existing condition that becomes worse before menstruation. For example, depression may remain present throughout the month and intensify premenstrually. PMDD assessment considers a different pattern, including improvement outside the symptomatic window. Real presentations can be complicated, which is why a clinician needs the whole timeline.
The ISPMD consensus on diagnostic measurement emphasizes prospective ratings and distinguishing core premenstrual disorders from exacerbations of another condition. A review of prospective studies of PME also found variation across disorders and research methods. Do not assume a treatment studied for PMDD will automatically address ongoing depression, anxiety, or another condition that worsens with the cycle.
A useful appointment question is: “Which symptoms are present all month, which change around bleeding, and what would that mean for treatment?” You do not need to decide the answer first. If you have an existing diagnosis, include it and ask how the two parts of the picture should be assessed together.
Use an easy time cue, such as your evening meal. Record what happened today, not what you expect your cycle to make happen.
| Field | Useful detail | Example |
|---|---|---|
| Date and bleeding | Actual start/end dates; spotting if relevant | Bleeding began today |
| Emotions | Irritability, sadness, anxiety, sensitivity | Irritable and tearful |
| Intensity | Consistent words or your clinician's scale | Moderate; more intense than usual |
| Physical symptoms | Pain, bloating, breast tenderness, headache | Headache in the afternoon |
| Sleep and energy | Brief, separate observations | Interrupted sleep; low energy |
| Daily-life impact | What became harder or impossible | Left a meeting; canceled plans |
| Context | Illness, stress, medication changes | Deadline; prescription changed last week |
You can record “none today” for a symptom. That is data too. Keep the wording stable enough that you understand it next month, but do not spend time debating whether a feeling is exactly a two or a three.
A low mood rating can hide very different experiences. “Sad but able to work” and “unable to get out of bed” deserve different notes even if the number is the same. Include the impact you want your clinician to understand.
The Daily Record of Severity of Problems, or DRSP, is a standardized daily rating instrument studied for reliability and validity. It covers symptoms and interference with activities. If your clinician recommends it, ask for the correct form, instructions, and an appropriate language version. A translation you find online is not necessarily a validated translation.
The Carolina Premenstrual Assessment Scoring System, C-PASS, was developed to apply diagnostic criteria to at least two months of daily DRSP ratings. Its study found that retrospective impressions were poor predictors of a diagnosis based on daily records. That helps explain why a clinician may ask for daily ratings even when you are already confident that there is a cycle-related pattern.
Our template is deliberately simpler. It helps organize a conversation but cannot calculate a PMDD diagnosis. Do not combine its personal intensity words with a DRSP cutoff or count a period app's predicted “luteal days” as confirmed observations. If a standardized form feels too demanding, ask for help completing it rather than silently changing the scoring system.
This is a fictional illustration, not a typical cycle or a diagnostic rule:
A useful summary is “I noticed a similar sequence in two cycles, with a clearer stretch of relief between difficult periods.” A less useful conclusion is “My chart proves PMDD.” The first invites assessment; the second asks the diary to do something it cannot do.
Now imagine the low mood continues throughout the month. Record that honestly too. Do not edit away persistent symptoms to make the chart resemble an example. Bring both the cyclical changes and the ongoing difficulty to your appointment.
Leave missed days blank or mark them “not recorded.” If you write a retrospective note, label it as memory. Do not convert remembered distress into precise scores for every missing date.
Note starting, stopping, or changing hormonal contraception, other prescribed medicines, and major changes in health or routine. Record the event without assuming it explains your symptoms. Never stop or alter prescribed treatment to create a “cleaner” baseline.
If tracking becomes distressing, shorten the entry to a few key observations and discuss a manageable approach with your clinician. The diary should serve you, not turn your month into a test you have to pass.
If your cycle is irregular, keep actual dates and describe uncertainty. If hormonal contraception, pregnancy-related changes, or another health issue affects bleeding, tell the clinician. A calendar prediction cannot resolve those differences. Continue prescribed treatment unless your prescriber recommends otherwise.
You can add one sentence about unusual context: a night shift, an infection, bereavement, or a medication change. The purpose is to prevent an important circumstance from disappearing into a symptom average. It is not to dismiss a recurring pattern as “just stress.” Both the pattern and the context can deserve attention.
You can use mood check-ins and journal notes to record your experience and the daily-life context above. Cycle-related features, where available, may help organize dates. A general mood app is not the same as a validated PMDD assessment instrument, and a predicted cycle phase is not a diagnosis.
You can also use a notebook or the specific form your clinician provides. Choose the format you can maintain and feel comfortable sharing. Cycle and mental-health notes are sensitive; review device access, backup settings, and exactly what you are sending before sharing a record.
Bring the diary, a medication list, and a brief description of the hardest days. Useful questions include:
ACOG's treatment guideline covers multiple approaches; choosing among them requires individual assessment. Viral advice about supplements or combinations of over-the-counter medicines is not a substitute for that assessment. Ask a clinician or pharmacist before trying a new product, especially alongside prescribed medicines.
For organizing the visit, use our therapy and appointment notes guide. If your concern is low mood beyond the premenstrual window, our depression guide provides additional context.
Tracking should lead toward care when needed, not become an endless substitute for it. ACOG's guideline covers several options, and the choice depends on symptoms, health history, preferences, contraception needs, and other conditions. The following evidence explains questions to bring, not a prescription to follow.
A 2024 Cochrane review found that SSRIs probably reduce premenstrual symptoms. Adverse effects also matter. Ask how benefits and tolerability would be monitored in your case, and what to do if problems arise.
A Cochrane review of drospirenone-containing pills found possible benefit, with low-quality evidence for key outcomes and more withdrawals due to adverse effects. Ask whether your health history and contraception needs make this an appropriate option.
A meta-analysis of cognitive behavioral interventions found possible benefits. A structured psychological treatment is different from completing a writing exercise on your own. Ask what the sessions would involve and which difficulties they would address.
A review of exercise trials found improvement in PMS symptoms, with substantial variation and study limitations. Ask what activity is realistic as a complement to care, especially when symptoms already make daily tasks difficult.
The exercise evidence concerns PMS and should not be presented as proof that exercise alone treats severe PMDD. Likewise, a medication's average trial result cannot tell you whether it will suit you personally. Bring questions about unwanted effects and what to do if symptoms worsen.
The RCOG patient guidance suggests continuing symptom records for a period after starting treatment to help assess the response. Agree on what to record and when to review it. Daily functioning, side effects, and safety matter alongside symptom scores.
Contact a healthcare professional when symptoms disrupt your life or feel difficult to manage. If you feel at risk of harming yourself or unable to stay safe, seek urgent local mental-health or emergency care immediately. Do not wait for another cycle or another journal entry.
No. You can book now and bring whatever information you have. Daily records across cycles can assist assessment, but severe symptoms deserve timely care.
No. Predicted period dates do not establish symptom timing or daily-life impact, and an app cannot rule out other explanations. Diagnosis needs clinical assessment.
Yes. Better days help show the course of symptoms. Recording only difficult days leaves an important part of the picture missing.
