PMS, PMDD and Migraines: Why Headaches Come Before Your Period

Medically reviewed by Mark Strehlow, MD, Medical Director — September 2026

Headaches before a period are common. For more than half of women who get migraines, attacks cluster around their period, a pattern called menstrual migraine. The usual trigger is the normal drop in estrogen just before bleeding starts, not an abnormal hormone level. Headache is also a common symptom of premenstrual syndrome (PMS) and its severe form, premenstrual dysphoric disorder (PMDD), but whether PMDD makes migraine itself more likely isn’t settled. A diary kept for two or three cycles shows your own pattern. One safety point matters most: if your migraines come with aura, birth control that contains estrogen isn’t advised.

What are PMS and PMDD?

PMS is a set of physical and emotional symptoms in the days before a period that ease once it starts. More than 90% of women notice some premenstrual symptoms, such as bloating, headaches, moodiness or food cravings. About 20% to 30% have symptoms that meet the medical criteria for PMS.

PMDD affects up to 5% of women of childbearing age. It causes severe irritability, depression or anxiety in the week or two before a period, and the symptoms usually go away two to three days after the period starts. Other symptoms include panic attacks, crying spells, trouble concentrating, feeling out of control, and physical symptoms such as cramps, bloating, breast tenderness and headaches. Some women with PMDD have thoughts of suicide.

If PMDD brings thoughts of suicide or of hurting yourself, call or text 988 (988 Suicide & Crisis Lifeline), or chat at 988lifeline.org. If you’re in immediate danger, call 911.

No lab test can detect PMS or PMDD. Doctors diagnose them from daily symptom ratings kept for at least two cycles, which should show symptoms before the period and relief after it.

Are headaches a symptom of PMS?

Yes. Headache is one of the most common PMS symptoms, and PMS can also make existing migraines worse. A premenstrual headache may be an ordinary headache or a migraine. Migraine pain is usually throbbing or pounding, often on one side of the head, and it can come with nausea, vomiting and sensitivity to light or sound.

What is menstrual migraine?

Headache specialists use two definitions:

  • Pure menstrual migraine: attacks happen only in the window from two days before your period to the third day of bleeding, in at least two out of three cycles. This form is rare.
  • Menstrually related migraine: attacks happen in that window in at least two out of three cycles, and at other times too.

Menstrual attacks are often more severe and longer than other migraines, and they bring more sensitivity to light.

Why it happens. Estrogen falls quickly in the last days before a period. In a study that tracked hormones and headaches in 38 women with migraine, attacks were more common in the days of falling estrogen around the period, and less common while estrogen was rising.

Why a diary matters. In a study of 607 women, their own sense of whether they had menstrual migraine was often wrong when checked against a diary. Noting headache days and period days for two or three cycles shows the real pattern, and when to act.

PMDD and migraines: is there a link?

Possibly, but the evidence is thin and mixed.

  • In a small study of 21 women with migraine, cycles with worse PMS symptoms also had more headache.
  • In a population study of 126 women with migraine, premenstrual symptoms were just as common in women whose migraines were tied to their period as in women whose migraines weren’t.
  • In a 2026 study of about 600 women with migraine, PMDD was found in 5.6% of those with menstrual migraine and 1.9% of those without, a difference that could have been due to chance. Women with PMDD did report a heavier headache burden.

What PMS, PMDD and menstrual migraine clearly share is timing: all three follow the normal hormone changes of the cycle. If you have both PMDD and migraines, each deserves its own treatment.

Is it a hormone imbalance?

Usually not, in the sense of abnormal hormone levels. Research at the National Institutes of Health found that women with PMS have an abnormal response to normal hormone changes, and menstrual migraine follows the normal fall in estrogen before every period. That’s why blood tests of estrogen and progesterone don’t diagnose PMS, PMDD or menstrual migraine, and why treatment targets the symptoms and the timing of the hormone drop, not “rebalancing” hormone levels.

What helps

  • Treat attacks early. For menstrual migraine, a fast-acting triptan (a prescription migraine medicine) taken early in the attack, combined with an anti-inflammatory painkiller (an NSAID), may be enough. Ask your clinician which medicines suit you.
  • Short-term prevention around your period. If your periods are regular, your clinician may suggest taking naproxen or a long-acting triptan for a few days around your period. These are off-label uses, not FDA-approved ones, so they need a clinician’s advice.
  • Magnesium. The American Migraine Foundation says daily magnesium has been shown to help prevent menstrually related migraine, especially attacks before the period. Check with your clinician before starting it.
  • Treat PMS or PMDD itself. The American College of Obstetricians and Gynecologists (ACOG) recommends SSRI antidepressants, taken every day or only in the second half of the cycle, combined birth control pills, and cognitive behavioral therapy. Exercise may also help. For severe PMDD that doesn’t respond, medicines that temporarily switch off the ovaries (GnRH agonists) are an option before surgery is considered.
  • Hormonal birth control, if it suits you. Taking combined birth control pills continuously, without the monthly break, can reduce menstrual migraine by avoiding the estrogen drop. That’s only an option if estrogen is right for you. See the next section.
  • Watch how often you use painkillers. Using them too often can cause more headaches (medication-overuse headache). This can happen with over-the-counter painkillers on 10 to 15 days a month, or triptans on more than 9 or 10 days a month. If you need them that often, ask your clinician about prevention.

Estrogen, birth control and migraine with aura

An aura is a warning phase before a migraine, such as temporary blind spots, zigzag lines or flashing lights. It often starts 10 to 15 minutes before the headache.

If you have migraine with aura, the CDC’s contraception guidelines class birth control that contains estrogen (the combined pill, patch and ring) as an unacceptable health risk. Migraine with aura raises the risk of ischemic stroke, and estrogen-containing contraception adds to it. Progestin-only methods (the mini-pill, implant, shot and hormonal IUD) and the copper IUD carry no restriction for migraine.

If you have migraine without aura, including menstrual migraine, the same guidelines generally allow estrogen-containing birth control: the benefits usually outweigh the risks.

Tell your prescriber if you have aura, if your aura is new, or if it changes.

Menopausal hormone therapy is different. It uses lower, body-level doses of estradiol, not the ethinyl estradiol in birth control. UK headache specialists say migraine with aura doesn’t rule it out, and suggest the lowest dose that controls symptoms, given through the skin as a patch or gel. US sources are more cautious: the American Migraine Foundation notes that experts disagree. If you have aura and are considering hormone therapy, decide with a clinician who knows your history.

Perimenopause: worse before better

In the years before menopause, periods and hormone swings become less predictable, and migraines may become more frequent or more painful. After menopause, many women find their attacks ease or stop as hormone levels settle. If perimenopause is also bringing low mood that won’t lift, read about depression during perimenopause.

When to get urgent care

Call 911 or go to the nearest emergency room if a headache comes on suddenly and is explosive or violent.

Get medical help right away if a headache:

  • is the worst you’ve ever had
  • comes with slurred speech, a change in vision, trouble moving your arms or legs, loss of balance, confusion or memory loss
  • comes with fever, a stiff neck, nausea and vomiting
  • follows a head injury

See a doctor soon if you’ve just started getting headaches, especially after 50, or if aura symptoms start suddenly, last longer than an hour or don’t fully go away.

Where Rock Creek Wellness fits

We’re a hormone and longevity clinic, not a headache clinic. For migraine, your primary care doctor, gynecologist or a neurologist is the right place to start, and your gynecologist or primary care doctor can diagnose and treat PMS and PMDD.

Where we can help is perimenopause. If your cycles, sleep, mood or headaches are changing in your 40s, we start with an evaluation of your symptoms, your health history, including migraine and any aura, and your medicines. Comprehensive blood testing looks for other causes of symptoms, such as thyroid problems. If hormone therapy may suit you, your provider goes through the benefits and the risks with you. If something points outside our care, we’ll tell you and help you take the next step.

Common questions

Can PMDD cause headaches?
Yes. Headaches are among the physical symptoms of PMDD, along with cramps, bloating and breast tenderness. Whether PMDD makes migraine itself more likely isn’t settled.

Will hormone therapy help my migraines?
Hormone therapy isn’t recommended as a migraine treatment on its own. Some women do better with a patch because it gives steadier hormone levels. If you have migraines, especially with aura, talk it through with your clinician before starting.
