PMDD Symptoms

PMDD Symptoms: All 11 Signs and How to Tell If It's You

By Leila Martyn, Founder of MyOva

PMDD (premenstrual dysphoric disorder) has 11 recognised symptoms. Four are core mood symptoms: sudden mood swings, irritability or anger, low mood or hopelessness, and anxiety or tension. The other seven are losing interest in things, trouble concentrating, exhaustion, appetite changes or cravings, sleeping too much or too little, feeling overwhelmed, and physical symptoms like bloating and breast tenderness. To count as PMDD, you need at least five of them, including at least one core mood symptom. They show up in the week or two before your period, ease within a few days of it starting, and are mostly gone the week after [1, 2].

You're not imagining it. If you feel like a calm, capable person for three weeks and someone you barely recognise for one, there's a name for that pattern, and it isn't "just PMS". A 2024 Oxford-led meta-analysis of more than 50,000 people found that 3.2% met criteria for a confirmed PMDD diagnosis, and 7.7% for a provisional one [3]. Below I'll go through all 11 symptoms, what an episode can feel like, when symptoms start, and how to track them so your GP takes you seriously.

This guide is all about symptoms. If you want to know how PMDD differs from bad PMS, read PMDD vs severe PMS. For treatment options and what the evidence says, see our PMDD support guide. And if the second half of your cycle is a mystery, start with the luteal phase explained.

If you're struggling right now

If you're having thoughts of suicide or harming yourself, you don't have to wait for your period to pass. Call Samaritans free on 116 123 (24 hours), call NHS 111, or call 999 or go to A&E if you're in immediate danger. PMDD is a real, medical condition, and help is available.

What are the 11 symptoms of PMDD?

In short: Four core mood symptoms plus seven others. A diagnosis needs at least five, with one or more core mood symptoms, before most periods.

The 11 symptoms come from the DSM-5, the diagnostic manual psychiatrists use worldwide. PMDD was moved into its own category in 2013 after a major review of the evidence [1, 4]. Here's the full list, with the clinical wording translated into how it tends to show up in real life.

The four core mood symptoms (you need at least one)

  1. Mood swings. Sudden sadness, tears out of nowhere, or feeling crushed by a comment you'd normally shrug off. The DSM-5 specifically mentions increased sensitivity to rejection [1].
  2. Irritability or anger. A short fuse, snapping at people you love, or more arguments than usual. Many women describe this as rage, not mild annoyance.
  3. Low mood or hopelessness. Feeling down, hopeless, or turning on yourself with harsh thoughts about your worth.
  4. Anxiety or tension. Feeling keyed up, on edge, or braced for something bad without knowing what.

The seven other symptoms

  1. Losing interest in work, friends, hobbies or things you normally enjoy.
  2. Trouble concentrating. Brain fog, rereading the same email three times, losing your train of thought.
  3. Exhaustion. Lethargy, getting tired easily, or a flat-battery feeling that sleep doesn't fix.
  4. Appetite changes. Overeating or strong cravings, often for sugar or carbs.
  5. Sleep changes. Sleeping far more than usual, or struggling to sleep at all.
  6. Feeling overwhelmed or out of control, like ordinary life is suddenly too much.
  7. Physical symptoms such as breast tenderness or swelling, joint or muscle pain, bloating or weight gain.
DSM-5 rule What it means in practice
At least 5 of the 11 symptoms One or two symptoms on their own point more towards PMS.
At least 1 core mood symptom PMDD is mainly a mood condition. Physical symptoms alone don't count.
Present in the final week before your period Symptoms follow your cycle, not your diary.
Ease within a few days of bleeding, minimal the week after There's a clear symptom-free window each month.
In most cycles over the past year One awful month isn't enough on its own.
Causes real distress or gets in the way of life Work, relationships or daily functioning take a hit.
Confirmed by daily ratings over at least 2 cycles Memory isn't enough. A symptom diary is the evidence.

Source: DSM-5 criteria for premenstrual dysphoric disorder [1], summarised in plain English.

The NHS uses a shorter list, but it lines up: feeling depressed, hopeless, anxious or worried, angry or irritable, losing interest, feeling overwhelmed and having suicidal thoughts, plus breast tenderness, joint and muscle pain, tiredness, sleep problems and bloating [2].

What does a PMDD episode feel like?

In short: Many women describe feeling like a different person for a week or two: flooded with rage, despair or dread, then back to themselves.

A checklist can't capture what PMDD is like to live with. The most common thing women tell me is some version of "it's like someone else takes over". For most of the month you're fine. Then, often around the same point each cycle, the floor drops out.

It can look like this:

  • A small comment from your partner feels like proof that nobody actually likes you.
  • You're suddenly certain you should quit your job, end your relationship or move house.
  • You cancel plans because people feel like too much, then feel guilty and alone.
  • Your thoughts turn dark and harsh, and they feel completely true at the time.
  • A few days into your period, the fog lifts and you look back thinking, "who was that?"

Mind, the mental health charity, describes feeling upset or tearful, for example if you feel others are rejecting you, and coming into conflict with the people around you [5]. That rejection sensitivity is one of the most painful parts, because it hits the relationships you need most.

The relief at the end is part of the pattern too. That symptom-free stretch after your period is what separates PMDD from ongoing depression or anxiety. And it's often why women doubt themselves: "I feel fine now, so maybe I made it up." You didn't. Your body is trying to tell you something, and the pattern is the message.

Suicidal thoughts are a symptom, not a weakness

A 2021 meta-analysis found women with PMDD were nearly four times more likely to have suicidal thoughts and around seven times more likely to have made a suicide attempt than women without it [6]. If dark thoughts arrive with your cycle, tell your GP, even if they've passed by your appointment. In a crisis, call Samaritans on 116 123, NHS 111 or 999.

When do PMDD symptoms start and stop?

In short: PMDD symptoms usually start 1 to 2 weeks before a period, after ovulation, and ease within a few days of bleeding starting.

The NHS says PMDD symptoms usually start around 1 or 2 weeks before each period and improve a few days after your period starts [2]. That window is the luteal phase, the stretch between ovulation and your period, when progesterone rises and then falls.

Every woman's timing is a little different. Some notice a short dip around ovulation, then a bigger crash in the last few days before bleeding. Others feel it build steadily for two weeks. What matters is that it repeats in the same part of your cycle, month after month.

Because PMDD is linked to ovulation, symptoms usually disappear when you're not ovulating. Mind notes it's unlikely you'll get symptoms during pregnancy [5], and they stop after menopause. That's an important clue that your cycle is the trigger, not your personality. If your cycles are irregular, as they often are with PMOS (PCOS) or in perimenopause, the timing can be harder to spot. That's exactly when tracking earns its keep.

Why does PMDD cause these symptoms?

In short: Hormone levels are usually normal in PMDD. The brain reacts differently to the normal rise and fall of oestrogen and progesterone.

This is the bit nobody explains, and it changes everything. Women with PMDD don't usually have "too much" or "too little" of a hormone. The research on this is actually pretty clear: it's a different sensitivity to normal hormone changes.

In a landmark study published in the New England Journal of Medicine, Schmidt and colleagues switched off the menstrual cycle using medication. Women with severe premenstrual symptoms felt better. When oestrogen or progesterone was added back, their symptoms returned, while women without premenstrual symptoms felt no change on the same hormones [7]. Same hormones, completely different response.

Later work from the US National Institutes of Health found differences in how a gene complex in cells from women with PMDD responds to sex hormones [8]. Other research points to allopregnanolone, a brain chemical made from progesterone that acts on the brain's calming GABA system. In PMDD, the brain seems to respond unusually to its rise and fall across the cycle [9].

Why does that matter? Because "your hormones are normal" from a blood test doesn't rule out PMDD, and it never meant it was all in your head. Hormonal literacy isn't complicated, it's just rarely taught.

What are the physical symptoms of PMDD?

In short: Bloating, breast tenderness, joint and muscle pain, headaches, tiredness, sleep changes and food cravings are the most common physical PMDD symptoms.

PMDD is mostly a mood condition, but your body joins in. Mind lists breast tenderness or swelling, muscle and joint pain, headaches, bloating, changes in appetite such as overeating or cravings, and sleep problems [5]. The NHS adds feeling more tired than usual [2].

Physical symptoms often make the mood symptoms heavier. It's hard to feel steady when you're puffy, sore, wired at 2am and running on biscuits. A few things that tend to help the physical side:

  • Eat little and often. The NHS suggests smaller, more frequent meals every 2 to 3 hours for premenstrual symptoms [10]. It can take the edge off cravings and energy crashes.
  • Move, gently or hard. A 2020 review of 15 randomised trials found exercise may help premenstrual symptoms, though the authors noted some uncertainty [11].
  • Protect your sleep. Keep regular wake-up times in your luteal week, even if nights are rough. Our guide to why you can't sleep before your period goes deeper.
  • Go easy on alcohol and caffeine in the days before your period, when sleep and anxiety are already fragile.

If evenings are the hardest part of your luteal week, a wind-down ritual can help you mark the end of the day. Ours happens to be chocolate.

MyOva Magnesium Nightcap chocolate drink
Evening wind-down
Magnesium Nightcap

A hot chocolate with magnesium, which contributes to normal psychological function and to the reduction of tiredness and fatigue, plus vitamin B6, which contributes to the regulation of hormonal activity. Contains chamomile: not suitable if you're allergic to plants in the daisy family. Not suitable in pregnancy or breastfeeding. Speak to your GP first if you take medication.

How do I know if I have PMDD?

In short: There's no blood test for PMDD. It's diagnosed by tracking symptoms daily for at least two cycles and showing they follow your period.

Searching "PMDD test" or "do I have PMDD quiz" is a good first step, and online questionnaires can tell you whether it's worth a conversation. But no quiz or blood test can diagnose PMDD. The DSM-5 requires daily ratings over at least two symptomatic cycles [1], and the NHS suggests keeping a symptom diary for at least two cycles to share with your GP [2].

This is what I wish someone had told me: your diary is your evidence. It turns "I just feel awful sometimes" into a pattern a doctor can't wave away.

Quick self-check

Ask yourself these questions. If you answer yes to most, it's worth tracking properly:

  • Do mood symptoms show up in the week or two before most periods?
  • Do they ease within a few days of bleeding starting?
  • Do you have a week or more after your period when you feel like yourself?
  • Do you recognise at least five of the 11 symptoms above, including one of the first four?
  • Do they affect your work, relationships or how you cope day to day?

How to track PMDD symptoms in 5 steps

  1. Use a structured diary. The Daily Record of Severity of Problems (DRSP) is a validated tool that rates each PMDD symptom from 1 to 6 every day [12]. IAPMD, the international PMDD charity, has free trackers and an app.
  2. Rate every day, not just bad days. The good days prove the pattern. Do it at the same time each evening, in under two minutes.
  3. Mark day 1 of each period. That's the anchor your GP will line everything up against.
  4. Note what life threw at you. A big work week or poor sleep matters, so jot it down. It helps separate cycle effects from life effects.
  5. Track at least two full cycles, then take it to your GP along with any patterns you've noticed.

Could it be something else?

In short: Yes. Depression or anxiety that worsens before periods (PME), thyroid problems and perimenopause can look like PMDD. A symptom-free week is key.

Your diagnosis is a starting point, not a verdict. Getting the label right matters because it changes what helps. The main lookalikes are:

  • Premenstrual exacerbation (PME). If you live with depression, anxiety or another condition all month, and it gets worse before your period, that's PME rather than PMDD [13]. The giveaway is that you don't get a symptom-free week. PME is just as real and just as worth raising.
  • Severe PMS. Mostly physical symptoms, with milder mood changes. Our PMDD vs severe PMS guide walks through the differences.
  • Thyroid problems. An underactive thyroid can cause tiredness, low mood and changes to your periods. A simple blood test can check. See our thyroid health guide.
  • Perimenopause. Mood swings, anxiety and poor sleep in your 40s can come from fluctuating hormones, with or without PMDD.

Some people can have more than one of these at once. That's why your diary and an honest conversation with your GP matter more than any checklist.

Is PMDD more common with ADHD?

In short: It seems to be. In a Dutch study of 209 women at an ADHD clinic, more than 45% self-reported symptoms suggestive of PMDD.

If you have ADHD and your focus, emotions and coping fall apart before your period, you're far from alone. A study of 209 women attending an ADHD clinic in the Netherlands found that more than 45% reported symptoms suggestive of PMDD [14]. These were self-reported symptoms, not confirmed diagnoses, so the true figure may be lower. But it's a strong signal.

Part of the challenge is overlap. Poor concentration, emotional swings and feeling overwhelmed are already part of ADHD for many women, so a luteal-phase dip can feel like your ADHD medication "stops working". Tracking both conditions side by side helps you and your clinician see what's cyclical. If you're on ADHD medication, don't change your dose yourself. Bring your diary to your prescriber.

Do PMDD symptoms change in perimenopause?

In short: They can feel worse or less predictable as hormone swings grow and cycles become irregular, then stop after menopause when ovulation ends.

Perimenopause is the run-up to menopause, when hormone levels swing more widely and cycles become erratic. If your brain is sensitive to hormone changes, more chaotic changes can mean a rougher ride. A US study that followed 436 women through the menopause transition for five years found those with PMS at the start were more than twice as likely to report depressed mood, and more likely to report hot flushes and poor sleep [15].

Irregular cycles also make PMDD harder to spot. When you don't know when your period is coming, you can't easily link a dark week to it. Keep tracking anyway: even with irregular cycles, a pattern of symptoms clearing after bleeding is a useful clue.

The light at the end: once periods stop for good after menopause, PMDD symptoms stop too. In the meantime, our complete guide to perimenopause explains what's changing and what helps.

When should you see a GP about PMDD symptoms?

In short: See a GP if you think you might have PMDD, ideally with a symptom diary. Get urgent help straight away for thoughts of suicide or self-harm.

The NHS says to see a GP if you think you might have PMDD [2]. You don't need to wait until you have a perfect diary. Book in now, and start tracking while you wait. Take with you:

  • Your symptom diary, or notes on when symptoms start and stop.
  • Which of the 11 symptoms affect you most, and how they affect work, family and relationships.
  • Any history of depression, anxiety or ADHD, and any medication or contraception you use.
  • What you'd like to talk about, such as talking therapies, medication or hormonal options.

The NHS lists antidepressants, the combined pill, and talking therapies such as CBT among the treatments for PMDD, with specialist options if those don't help [2]. Our PMDD support guide goes through the evidence for each one.

If you've been brushed off before, you're in good company, and it's not OK. Our guide on advocating for yourself at the GP has scripts you can use, and they work for PMDD too.

Where do supplements fit?

Let's be clear: no food supplement treats PMDD, and anything that claims to deserves a hard pass. Food supplements can't replace medical care. What they can do is help fill nutritional gaps, using only the wording UK law allows for each nutrient. It's not a magic fix. But it gives your body what it's often missing, alongside the basics and any treatment your GP recommends.

MyOva Cycle Support food supplement
Daily food supplement
Cycle Support

With vitamin B6, which contributes to normal psychological function and to the regulation of hormonal activity, alongside ashwagandha, L-theanine, chamomile, turmeric, broccoli extract, rhodiola and 5-HTP. It isn't a treatment for PMDD. Contains 5-HTP and ashwagandha: don't take it with antidepressants or other medication that affects serotonin without speaking to your GP first, and avoid it if you have a liver condition. Not suitable in pregnancy or breastfeeding.

A note on vitamin B6: The NHS advises not taking more than 10 mg of vitamin B6 a day from supplements unless a doctor advises it [16]. Cycle Support provides 1 mg a day and Nightcap 5 mg, so check your total if you take other products containing B6.

Frequently asked questions

What are the 11 symptoms of PMDD?
Mood swings, irritability or anger, low mood or hopelessness, anxiety or tension, loss of interest, trouble concentrating, tiredness, appetite changes or cravings, sleeping too much or too little, feeling overwhelmed, and physical symptoms such as bloating and breast tenderness [1]. A diagnosis needs at least five, including one of the first four.

Can PMDD make you feel like a different person?
Yes, many women describe it that way. Symptoms like rage, despair and rejection sensitivity can feel overwhelming in the week or two before a period, then lift within a few days of bleeding starting [2, 5]. That on-off pattern is typical of PMDD.

Is there a test for PMDD?
No. There's no blood test or scan for PMDD, and hormone levels are usually normal [7]. It's diagnosed by recording symptoms daily for at least two cycles and showing they follow your period [1, 2]. Online quizzes can help you decide whether to track.

When do PMDD symptoms start?
Usually around 1 or 2 weeks before your period, after ovulation, and they ease a few days after your period starts [2]. Some women notice a short dip around ovulation too. Tracking shows your personal pattern.

Does PMDD get worse with age?
It can feel harder to manage in perimenopause, when hormone swings get bigger and cycles become unpredictable [15]. Symptoms stop after menopause, once ovulation ends. If things are changing in your 40s, it's worth reviewing with your GP.

The bottom line

PMDD symptoms are specific and recognisable: four core mood symptoms and seven others, arriving in the week or two before your period and lifting soon after it starts. Hormone levels are usually normal. It's your brain's response to them that's different, which is why PMDD was never a character flaw. You're not imagining it. Learn the 11 symptoms, track two cycles, and take that evidence to your GP. And if the dark days ever feel unsafe, reach out for help right away.
