Strength of evidence
Strong evidence
Meta-analyses and systematic reviews (n up to 8,532) link PMDD to roughly double to seven-times the odds of suicidal ideation and attempts versus no PMDD. A crossover trial shows restoring estradiol and progesterone blunts the perimenstrual spike in suicidal ideation, supporting hormone withdrawal as a driver.
Are you safe right now?
Before anything else, answer this as plainly as you can: do you have a plan to hurt yourself, or access to something you could use to carry it out. If the answer is yes, or you're not sure, treat this as an emergency. Get help now, not after you finish this page.
If you're safe enough to keep reading, know what's happening to you has a name and a pattern. In a small study of women with recurring suicidal thoughts, the sharpest rise in suicidal thinking came in the days right before a period started, with little change the rest of the month [6]. That doesn't make the thoughts less real. It does mean there's a reason, and a window where they tend to ease.

Who can you call or text right now?
Crisis lines exist for exactly this moment, and using one isn't an overreaction. In the US, call or text 988 any time, day or night. In the UK, call Samaritans on 116 123. Outside those countries, call your local emergency number, or look up a crisis line where you live.
Beyond a hotline, think of one person you could text right now: a partner, a friend, a sister, a parent. You don't need the right words. "I'm not okay and I need you to stay on the phone with me" is enough.
For a longer list of lines by country and what to say when you call, see PMDD crisis lines and helplines. Save that page, or write the numbers down somewhere you'll see them next month too.
What can you do in the next 10 minutes?
Once you've reached someone, or decided you're safe enough for now, the next ten minutes are about putting distance between you and the thought.
Move rooms if you can, and put anything you could use to hurt yourself somewhere you can't easily reach it. Hand it to someone else if there's someone nearby. Turn on a light, put on a show or music you know, and stay out of the dark alone.
Set a timer for 20 minutes. You don't have to decide anything beyond staying put until it rings. For practical, physical steps when your body won't settle, see how to calm down fast. Getting to morning is the only goal tonight.
Why does PMDD bring suicidal thoughts?
PMDD is a different reaction to the normal rise and fall of estrogen and progesterone, not a sign of abnormal hormone levels. In a crossover trial, giving people estradiol and progesterone through the days before a period blunted the usual perimenstrual spike in suicidal ideation, which suggests the hormone drop itself is part of what drives it [1].
The numbers are stark. Across a meta-analysis of over 8,500 women, PMDD was linked to roughly double the odds of suicidal ideation, suicide plans and suicide attempts compared with women without it (Journal of Affective Disorders, 2021) [5]. Another review found women with PMDD were almost seven times more likely to report suicidal ideation than women without it, though the increase in suicide attempts in that review wasn't statistically significant (Journal of Women's Health, 2021) [3]. In one study of women with a confirmed PMDD diagnosis, nearly 40% reported current suicidal thoughts in the late luteal phase, the week before bleeding starts (BMC Women's Health, 2022) [2].
Depression, hopelessness and feeling like a burden to people around you tend to rise together with suicidal thinking in that same week [4]. None of this means the thoughts aren't serious. It means they follow a pattern doctors can see, test for and treat. For the full research picture, see PMDD and suicidality: the research.
How do you make a safety plan for next cycle?
A safety plan is just a plan you make before you need it, written down while you're thinking clearly, not in the middle of a bad night.
A simple one has a few parts:
- Warning signs: the thoughts, days of your cycle or situations where this tends to start.
- People to call: at least two names and numbers, saved where you'll find them fast.
- What to remove or lock away: anything you could use to hurt yourself, given to someone else or stored somewhere less reachable.
- One thing that's helped before: a place, a person, a song, a message you've written to yourself for this exact moment.
Tracking your cycle alongside your mood for two months gives you, and a doctor, real data instead of guesswork, and it's part of how a PMDD diagnosis gets confirmed rather than assumed. Read more about PMDD and how it's diagnosed. For a plan you can fill in now, before your next luteal phase starts, use a PMDD safety plan you can build today.
Which treatments reduce PMDD suicidality?
Guidelines point to a few treatments that reduce PMDD symptoms overall, though a doctor decides what fits your history. SSRIs can work for PMDD, and some people take them only in the luteal phase rather than every day. Certain hormonal contraceptives can help by evening out the swings in estrogen and progesterone. Cognitive behavioral therapy gives you tools for the thoughts themselves, separate from the hormone pattern.
A recent systematic review of PMDD suicidality research found no studies yet that tested treatments specifically for reducing suicidal thoughts in PMDD, as opposed to PMDD symptoms generally (Administration and Policy in Mental Health, 2026) [7]. That's a real gap, so tell whoever treats you about the suicidal thoughts specifically, beyond the mood swings or cramps.
Finding a PMDD specialist covers how to find someone who treats this specifically.

Study, 2026
How do women with PMDD process emotions differently in their brains?
Women with PMDD show increased activity in emotion-processing brain networks, especially during the luteal phase, and this baseline difference even appears in the follicular phase and relates to symptom severity.
Strong study design
Case-control study, 2026
Do women with PMS handle emotions differently at different times of the cycle?
Yes. Women with PMS tend to use emotion coping strategies that make symptoms worse (like dwelling on negative thoughts) and fewer strategies that help (like accepting difficult thoughts). These patterns change across the menstrual cycle.
Strong study design
Systematic review, 2025
Do people with PMDD and severe PMS have difficulties with emotion regulation?
People with PMDD and severe PMS may have difficulties identifying emotions and choosing how to handle them, particularly using rumination (replaying upset thoughts) in the late-luteal phase. Evidence remains limited.
Strong study design
Systematic review, 2025
Does teaching adolescent girls about their menstrual cycle and health help reduce period pain and PMS?
Yes. A systematic review of five good-quality studies shows that psychoeducation (structured teaching) significantly reduced period pain and PMS symptoms and improved emotional wellbeing in adolescent girls.
Strong study design
Randomised trial, 2007
Does paroxetine work better if taken daily or just during your luteal phase for PMDD?
Daily paroxetine had an 85% response rate and was most effective overall, while luteal-phase-only paroxetine worked equally well for irritability and mood swings but was weaker for depression and physical symptoms. This well-designed study provides reliable results.
Strong study design
Survey study, 1994
How many different ways do researchers measure PMS in clinical trials?
Researchers use many different measurement tools across studies. 65 different questionnaires were found in 350 trials of PMS drugs, making it hard to compare whether treatments actually work.

Questions people ask
Can PMDD cause suicidal thoughts?+
PMDD is strongly linked to suicidal thoughts in the week before a period. Reviews find roughly double the odds of suicidal ideation compared with people without PMDD (Journal of Affective Disorders, 2021). PMDD suicidal thoughts usually track the hormone drop before bleeding and ease within days of the period starting, which doesn't make them less serious.
Why do I feel suicidal a week before my period?+
Suicidal thinking before a period tends to track the drop in estrogen and progesterone in the final cycle week. In a crossover trial, restoring those hormones blunted the usual rise in suicidal ideation (Translational Psychiatry, 2022), suggesting the hormone drop itself, not just mood in general, drives the pattern for some people.
How common is suicidal ideation during the luteal phase?+
In one study of women with confirmed PMDD, almost 40% reported current suicidal thoughts in the late luteal phase, the week before a period (BMC Women's Health, 2022). Rates varied widely across other studies, from roughly a quarter to the majority of participants with PMDD (Administration and Policy in Mental Health, 2026).
What should I do right now if I'm having suicidal thoughts before my period?+
If you're thinking about ending your life, call or text 988 in the US, call Samaritans on 116 123 in the UK, or call your local emergency number now. Then put distance between yourself and anything you could use to hurt yourself, and text one person you trust.
Can treatment reduce PMDD suicidal thoughts?+
SSRIs, some hormonal contraceptives and CBT can reduce PMDD symptoms overall, and a doctor decides what fits your history. No study has yet tested a treatment specifically for PMDD suicidal thoughts rather than PMDD symptoms generally, so tell your doctor about the thoughts directly, not only the mood or physical symptoms.
