Hormonal migraines: birth control, HRT and the estrogen drop beyond your period

Short answer

Hormonal migraines are migraine attacks set off by a change in sex hormones — most often a drop in estrogen. Your period is the best-known example, but the same drop happens in the pill-free week of combined birth control, when you stop estrogen-containing medicine, after giving birth, and during the swings of perimenopause. The international headache classification has a name for it: estrogen-withdrawal headache, which starts within 5 days of stopping estrogen that you took daily for 3 weeks or longer and settles within 3 days (2).

Hormones can also be part of the answer. Steadier hormone levels — for example, birth control without a hormone-free week, or HRT patches and gels rather than tablets — are options some doctors use; results vary. The one rule that changes everything is aura: the CDC classes estrogen-containing birth control as an unacceptable health risk for people with migraine with aura, because of stroke risk (5). HRT is different: migraine with aura does not rule out HRT (8).

If your migraines follow your pill packet or your HRT, you are not imagining it and you are not overreacting: brains prone to migraine appear to react more strongly to falling estrogen (4).

Note: This article explains research and guidelines. It is not medical advice. Do not start, stop or switch birth control or HRT because of this article — talk to your doctor first. Call emergency services for a sudden, extremely painful headache, weakness on one side of the body or face, trouble speaking, or vision loss (1).

What are hormonal migraines?

"Hormonal migraine" is not one formal diagnosis. It is an everyday name for migraine attacks that line up with hormone changes. Doctors use more precise labels:

This guide focuses on the parts the menstrual migraine guide only touches: birth control, stopping and starting estrogen, HRT and aura. If your attacks come only with natural periods, start with that guide.

Hormonal headaches vs hormonal migraines

People often search for "hormonal headaches." Hormone shifts can trigger both migraine and other headaches, but migraine has its own pattern: a throbbing headache, often on one side, with nausea or strong sensitivity to light and sound, usually lasting between 4 hours and 3 days (1). If you are not sure which you have, our guide is it a headache or a migraine? walks through the differences.

Why the estrogen drop matters more than the level

The key idea in hormonal migraine is not "too much" or "too little" estrogen. It is how fast estrogen falls.

A 2016 study in Neurology followed 114 women with a history of migraine and 223 women without, measuring hormone markers in daily urine samples across a cycle. Peak estrogen levels were the same in both groups. What differed was the fall after the peak: in the 2 days after the luteal peak, the estrogen marker dropped by about 40% in women with migraine versus about 30% in women without (4). The authors suggest that the timing and speed of estrogen withdrawal may be a marker of a vulnerable nervous system.

That one idea explains most hormonal migraine patterns:

• Before a period, estrogen falls at the end of the cycle.

• In the pill-free or placebo week, estrogen from the pill stops abruptly.

• When you stop estrogen — the pill, patch, ring or HRT — levels fall.

• After birth, estrogen drops steeply within days (12).

• In perimenopause, estrogen swings up and down unpredictably, so drops come at odd times (9).

High estrogen can matter too. A 2018 review by headache specialist Anne MacGregor notes evidence for estrogen "withdrawal" as a trigger of menstrual attacks of migraine without aura, while high estrogen levels can trigger migraine aura (17). That is one reason a new aura after starting an estrogen-containing medicine needs a doctor's attention.

Can birth control cause migraines?

It can — and it can also help. Which way it goes depends on the method, how it is taken and whether you have aura.

How combined birth control can trigger attacks. Combined pills, patches and rings contain estrogen and a progestin. In the classic 21/7 schedule, you take hormones for 3 weeks and then have a week off or a week of placebo pills. That break is a built-in estrogen drop, and many women with migraine notice attacks in that week. ICHD-3 describes estrogen-withdrawal headache as usually happening "during the pill-free interval of combined oral contraception" (2).

How birth control can help. Because the trigger is the drop, doctors may look at ways to keep hormone levels steadier — for example, shortening or skipping the hormone-free interval, or switching to a method without estrogen. EMAS lists contraceptive pills among the hormonal options used to stabilize hormone levels (9), and the European consensus on stroke risk places progestogen-only pills, implants and injections in its lowest-risk group (6). Skipping the hormone-free week is only an option for people who can use a combined method at all — not for migraine with aura (see the next section). Whether either is right for you is a decision to make with your doctor, who will weigh your blood pressure, smoking, clotting risk and other health factors.

What "started birth control and now I get migraines" can mean. A new headache pattern in the first months on a new method is worth reporting. A new aura after starting an estrogen-containing method needs a call to your doctor promptly, because aura changes which methods are suitable (see the next section).

Questions to log if you suspect your birth control

1. Which method, brand and schedule you use (21/7, 24/4, continuous).

2. Which day of the pack, patch or ring cycle each attack starts.

3. Whether attacks cluster in the hormone-free or placebo days.

4. Whether you had aura: visual zigzags, blind spots, tingling, trouble finding words.

5. Any missed pills, late patch changes or ring removals before an attack.

Two or three cycles of this record usually tell your doctor more than any single appointment can.

Migraine with aura and birth control: the stroke question

This is the safety point every woman with migraine should know.

What the guidelines say. In the 2024 US Medical Eligibility Criteria for Contraceptive Use, the CDC rates combined hormonal contraception (the combined pill, patch and ring) as category 4 — "an unacceptable health risk" — for people with migraine with aura. For migraine without aura, the same methods are category 2, meaning the benefits generally outweigh the risks. Progestin-only pills, the implant, the injection and both hormonal and copper IUDs are category 1 — no restriction — for migraine with or without aura (5).

Categories: 1 = no restriction; 2 = advantages generally outweigh risks; 4 = unacceptable health risk. Source: CDC, checked November 10, 2026 (5).

Why. Migraine with aura is itself linked to a higher risk of ischemic stroke. A consensus statement from the European Headache Federation and the European Society of Contraception reported a pooled relative risk of 2.3 for migraine with aura, and noted that combined hormonal contraception may raise that risk further (6). The same panel stressed that the absolute risk in young women is low — about 2.5 ischemic strokes per 100,000 women per year among young women not using hormonal contraception — and that the quality of evidence is low (6). Low absolute risk is why most women never have a stroke; a higher relative risk is why guidelines avoid adding estrogen for women with aura.

What this means in practice.

• If you have migraine with aura and use a combined pill, patch or ring, do not stop it suddenly on your own — that can lead to an unplanned pregnancy and an estrogen-withdrawal attack. Book an appointment soon and ask about switching.

• If you have never told your prescriber you get aura, tell them. Many people do not realize the visual zigzags before a headache count.

• If you develop aura for the first time while using estrogen, contact your doctor promptly.

• Searches for the "best birth control for migraines with aura" usually lead to the methods in category 1 above, but the right choice still depends on your health, preferences and other risks.

Stopping, starting or switching hormones

Any change in hormones can shift your migraine pattern for a while.

• Stopping the pill, patch or ring. Estrogen falls, and ICHD-3 notes that headache or migraine can develop within 5 days and resolve within 3 days (2). After that, your natural cycle returns, and with it any menstrual pattern you had before.

• Starting a new method. The first 2–3 months are often unsettled. Track rather than judge too early — unless you get a new aura or a very different headache, which needs a call.

• Stopping HRT. Estrogen withdrawal applies to HRT too: ICHD-3 lists stopping "a course of replacement or supplementary estrogen" as a cause of estrogen-withdrawal headache (2). Ask your doctor about how to stop.

• After pregnancy. The steep postpartum drop in estrogen is linked with migraine returning in the first weeks after birth (12).

HRT and migraines

Hormone replacement therapy (HRT, also called menopausal hormone therapy) is where the advice is often confused with birth control advice. They are not the same.

Migraine, including migraine with aura, does not rule out HRT. The Migraine Trust puts it plainly: "Having migraine, including migraine with aura, does not mean that you can't take HRT" (8). The European Menopause and Andropause Society (EMAS) states that migraine aura, with or without headache, is not a contraindication to estrogen replacement (9). The reason is the type and dose of estrogen: HRT uses natural estrogen at lower doses than the synthetic estrogen in combined birth control (8).

Patches, gels and sprays are usually preferred. The Migraine Trust says doctors usually recommend HRT patches, gel or spray rather than tablets for women with migraine, because these give more stable hormone levels (8). EMAS adds that transdermal delivery is less likely to have a negative effect on migraine than oral therapy (9), and a 2024 clinical review notes that small studies link worsening migraine with oral estrogen, while transdermal estrogen appears neutral (10). NHS notes separately that HRT patches, sprays and gels do not increase the risk of blood clots, and that HRT tablets — but not patches, gel or spray — slightly increase stroke risk (7).

The progestogen part matters too. If you have a womb, HRT includes a progestogen. The same review notes one randomized trial in which cyclical HRT had a greater adverse effect on migraine than continuous combined HRT, while adding that data on different progestogens are limited (10).

Results vary. Some women find HRT helps their migraine, and others find it makes it worse (8). If attacks change after starting or adjusting HRT, keep a log and talk to the prescriber rather than stopping suddenly.

For the wider menopause picture, see perimenopause and menopause treatment: what works.

Does migraine go away after menopause?

Often it improves. NHS notes that migraine often improves after the menopause (1), and the Migraine Trust says it is common for attacks to become less severe and less frequent at this time — but not always, and continuing or worsening migraine is more likely after surgical menopause (8). In the years before, during perimenopause, migraine may worsen because estrogen levels fluctuate (9).

How to track a hormonal migraine pattern

Hormonal patterns are hard to see from memory, especially on birth control, where your "period" may be a withdrawal bleed or absent. ICHD-3 recommends diary records over at least three cycles to confirm menstrual migraine (3). A simple method:

1. Mark your hormone events: pill-pack day 1, first placebo or hormone-free day, patch or ring changes, any bleeding, HRT starts, stops and dose changes.

2. Log every attack: start date and time, how bad (0–10), aura yes or no, how long it lasted.

3. Log what you took and whether it worked.

4. Add the everyday context: sleep the night before, skipped meals, alcohol, stress, travel.

5. Review after 3 cycles: do attacks cluster within a few days of a hormone drop? Are hormone-linked attacks longer or harder to treat?

6. Bring the record to your doctor before changing anything.

If you do not bleed on your birth control, track by the pack or patch schedule instead. Our migraine headache diary guide has a template.

Living with hormonal migraines: the questions people ask next

How long do hormonal migraines last?

NHS says migraine attacks usually last between 4 hours and 3 days (1). Many women find hormone-linked attacks among their longest. By definition, an estrogen-withdrawal headache resolves within 3 days of starting (2). NHS advises urgent advice for any attack lasting longer than 72 hours (1).

What helps hormonal migraines?

Two strategies: treat the attack, and reduce the drop. Acute treatment is the same as for other migraine and is something to plan with your doctor (see migraine treatment). Reducing the drop can mean a different birth control schedule or method, or a steadier HRT route such as a patch or gel — always with your prescriber (6, 8).

Can the progestin-only pill cause migraines?

Any hormone method can change your headache pattern in the first months. Progestin-only methods do not contain estrogen and are category 1 for migraine with and without aura in the CDC criteria, so they are not restricted for stroke-risk reasons (5). If headaches start or worsen, log them and tell your prescriber.

I have migraine with aura — what birth control can I use?

The CDC lists progestin-only pills, the implant, the injection and hormonal and copper IUDs as category 1 (no restriction) for migraine with aura, and estrogen-containing pills, patches and rings as category 4 (5). Your doctor will help you choose among them.

What is the best HRT for migraine sufferers?

There is no single best product. The Migraine Trust says doctors usually recommend patches, gel or spray over tablets for women with migraine (8), and reviews favor steady, continuous regimens over cyclical ones (10). Your prescriber will match the regimen to your symptoms and risks.

Before you blame yourself

When attacks keep landing on the same days of your pack, or after a change in HRT, it is easy to think your body is "overreacting" or that you are too sensitive. The research suggests something more specific: in one study, women with migraine had a faster estrogen fall after the cycle's peak than women without migraine, even though their hormone levels were the same (4). That is a difference in how your system responds, not a failing.

Before you blame yourself, look at what your record already shows. Do attacks start within 1–5 days of a hormone drop? Do they come with shorter sleep in the same week? Pick one lever you control — for example, protecting your sleep and meal times in the 3 days around your hormone-free week — and keep it for 1–2 cycles. Any change to the hormones themselves is a conversation with your prescriber, using the record you have built.

When to see a doctor

Contact your doctor promptly if you:

• develop aura for the first time, especially while using estrogen-containing birth control or HRT;

• notice your aura changing — lasting longer, or with weakness, numbness or speech problems;

• have a new headache pattern after starting or changing a hormonal method;

• regularly get migraine before or during your period or bleed (1).

See a GP or doctor if attacks are severe or getting worse, happen more than once a week or are difficult to control (1).

Get urgent advice if an attack lasts longer than 72 hours, if aura lasts more than 1 hour, or if you are pregnant or have just had a baby (1).

Call emergency services for a sudden, extremely painful headache; problems speaking or remembering; vision loss or double vision; drowsiness or confusion; a seizure; a very high temperature with signs of meningitis; weakness on one side of the body or face; or a headache after a recent head injury (1).

How to bring this up with your doctor

• Lead with aura. Say clearly whether you get aura and what it looks like. It decides which hormonal options are suitable for you.

• Bring 3 cycles of records: pack or patch days, bleeding, attack days, aura and what you took.

• Ask by name: "Could my migraines be estrogen-withdrawal attacks?" "Would a continuous schedule or a progestin-only method make sense for me?" "For HRT, would a patch or gel suit my migraine better than tablets?" "Is continuous combined HRT an option for me?"

• Mention other risk factors honestly: smoking, blood pressure, clotting history, family history of stroke.

• If you feel dismissed, say: "My migraines follow my hormone changes and affect my work. I would like a plan for both the attacks and the hormone side, or a referral to a headache specialist or menopause clinic."

How Welltory helps — and what it cannot do

What it cannot do. Welltory is a general wellness product, not a medical device. It does not measure hormones, it does not diagnose migraine or tell you which birth control or HRT to use, and it cannot predict an attack — our review of whether a smartwatch can predict a migraine explains why.

What it can do is keep the context around your hormone changes and attacks in one place:

• Tag what happened. If you use an iPhone with an Apple Watch or Oura ring, the Today screen flags stress stretches and asks "What happened?" — tap a tag or type a few words: "migraine," "placebo week day 2," "new patch," "started HRT gel."

• Sleep, resting heart rate and activity from your watch or ring. You can connect Apple Health, Health Connect and other sources.

• A quick heart rate and HRV reading with your phone camera. It is a spot reading, not continuous monitoring; follow the measurement guide and the tips for accurate HRV readings.

• Looking back at patterns. On iOS, My Patterns shows how your measurements relate to what you log, so you can look at the days around each hormone change.

• A log for your doctor. You can export your data as a CSV file from the web app. Patterns are links to discuss with your doctor, not proof of a trigger.
