How do I know if I have PMDD?
You might have PMDD if severe mood symptoms, such as depression, hopelessness, anger, anxiety or mood swings, show up in the week or two before your period, disrupt your life, and lift within a few days of bleeding, nearly every cycle. Only a doctor can diagnose it, usually after you track symptoms daily for at least two cycles.
PMDD can bring suicidal thoughts. If you have thoughts of harming yourself, please reach out now: call your local emergency number, or in the US call or text 988. In the UK, Samaritans are on 116 123.
The pattern doctors look for
PMDD (premenstrual dysphoric disorder) isn't diagnosed by a blood test. It's diagnosed by timing and severity. Using criteria from the DSM-5, a doctor looks for:
- At least five symptoms in the final week before your period, in most cycles over the past year
- At least one mood symptom: marked mood swings or sensitivity to rejection; marked irritability or anger; depressed mood or hopelessness; or marked anxiety or tension
- Other possible symptoms: less interest in usual activities, trouble concentrating, tiredness, appetite changes or cravings, sleeping too much or too little, feeling overwhelmed or out of control, and physical symptoms like breast tenderness or bloating
- Symptoms that improve within a few days of your period starting and are minimal or absent in the week after
- Real distress or interference with work, school, relationships or daily life
- Confirmed by daily ratings over at least two cycles

Why tracking two cycles matters
Memory blurs. Daily ratings show whether symptoms truly switch on before your period and off after it, which separates PMDD from depression or anxiety that's simply worse before periods (PME). Rate each symptom every evening, mark your period, and bring two cycles to your appointment. Our PMDD self-check is a good first step; it can't diagnose, but it helps you describe what's happening.
Lulu builds a PMS chart from your daily one-tap check-ins and exports it as a CSV, so you can show the pattern instead of trying to remember it.
What happens next
PMDD is very treatable. Options include SSRIs (which can work within days for premenstrual symptoms, and can be taken all month or just in the luteal phase), some combined pills, CBT, and lifestyle changes. See PMDD treatment and PMDD support.
Frequently asked questions
