Anxiety that spikes before your period is a common PMS symptom and can be severe in PMDD. What's behind it, how to track it, and which treatments help.
For a week or so every month, your chest is tight, small decisions feel huge, and a message from your manager reads like a threat. Then your period arrives and, before long, you feel like yourself again. It's easy to blame yourself for overreacting, until you notice it lands at the same point in every cycle.
Anxiety that gets worse before your period is a recognised symptom of premenstrual syndrome (PMS). The NHS lists feeling upset, anxious or emotional among the common symptoms. When it's severe enough to disrupt your life, it may be premenstrual dysphoric disorder (PMDD), which is treatable.
It's Your Sensitivity to Hormones, Not Your Levels
The NHS says the cause of PMS isn't fully understood. It may come from changes in hormone levels across the cycle, and some women are more affected by these changes than others.
Research on PMDD points the same way. At the US National Institute of Mental Health, women with PMDD had normal hormone levels but were abnormally sensitive to normal changes in sex hormones. When researchers switched off estrogen and progesterone, symptoms went away, and they came back when the hormones were added back.
That's why diagnosis rests on tracking your symptoms rather than on a hormone blood test. Researchers are still working out exactly what happens in the brain. Be wary of anyone selling a precise mechanism, or a supplement built on one.
PMS or PMDD
PMDD is a more severe form of PMS. The NHS describes its symptoms as much more intense, with a much bigger impact on everyday life. They can include feeling very anxious, angry, depressed or suicidal. NIH puts it at 2 to 5 percent of women of reproductive age.
If premenstrual anxiety stops you working, damages relationships or leaves you feeling hopeless, that's beyond ordinary PMS. There's more on telling them apart in the difference between PMDD and PMS.
Track It for Two Cycles
The most useful thing you can do this month is start a diary. The NHS suggests tracking symptoms for at least 2 menstrual cycles and taking the diary to your GP.
Each day, note the date, whether you're bleeding, and rate anxiety, mood, irritability and sleep from 0 to 3. The pattern to look for is symptoms that build in the second half of your cycle and ease once your period starts.
The diary also shows whether the anxiety is only premenstrual, or there all month and simply worse before your period. Your GP will want to know which. The wider picture is covered in how your cycle affects anxiety.
Treatments for Premenstrual Anxiety That Help
For milder symptoms, the NHS suggests regular exercise, plenty of sleep and lowering stress with things like yoga or meditation. Cutting back on alcohol and not smoking help too.
If that isn't enough, a GP may offer the combined contraceptive pill, cognitive behavioural therapy or antidepressants. For PMDD, Mind notes that SSRI antidepressants can be taken daily throughout the whole month or just during your luteal phase. That's the stretch between ovulation and your period.
The pill can help by controlling or stopping periods. Mind says the evidence is mixed and it's usually tried for three months. For severe PMDD that hasn't responded to anything else, specialists may use injections that bring on a temporary menopause.
Supplements such as magnesium are often suggested online for premenstrual anxiety. The NHS says there's not much evidence that they work. Check with a GP or pharmacist first, especially if you take other medicines.
Knowing the anxiety is hormonal doesn't always make it stop, and knowing why you're anxious without being able to stop it is its own frustrating experience. If the pattern shifts in your 40s, perimenopause and anxiety may be part of the picture.
When to Get Help Now
PMDD can bring suicidal thoughts. The NHS says to call 999 or go to A&E if you have PMDD symptoms and feel suicidal. You can also call Samaritans free on 116 123 in the UK at any time, or call or text 988 in the US.
See a GP soon if premenstrual anxiety is affecting your work or relationships, or if you dread the second half of every month. Take your diary with you.
Frequently Asked Questions
Is It Normal to Have Anxiety Before Your Period?
Yes. Feeling anxious, upset or emotional in the weeks before a period is a common PMS symptom. If it's severe or makes daily life hard, talk to a GP, as it could be PMDD.
How Do I Know If It's PMDD or PMS?
PMDD is a more severe form of PMS, with symptoms such as intense anxiety, anger, depression or suicidal thoughts that seriously disrupt your life. Tracking your symptoms for at least two cycles helps a GP see the pattern. NIH research suggests PMDD involves unusual sensitivity to normal hormone changes, not abnormal hormone levels.
Can the Pill or Antidepressants Help Premenstrual Anxiety?
They can. A GP may offer the combined contraceptive pill. For PMDD, SSRI antidepressants can be taken all month or only in the second half of the cycle. CBT is another option that helps some people.
