Menstrual Migraine
A pounding headache that lands like clockwork around your period? Menstrual migraine is triggered by the natural drop in oestrogen — and once you can predict it, you can plan for it.

Menstrual migraine is a migraine that is closely tied to your menstrual cycle, typically striking in the two days before a period or the first few days of bleeding. It's thought to be triggered by the natural fall in oestrogen that happens just before your period starts.
These attacks are often more intense, longer-lasting, and harder to treat than migraines at other times of the month. They usually appear as a throbbing pain on one side of the head, often with nausea and sensitivity to light and sound. Unlike many migraines, menstrual attacks less often come with an 'aura'.
The cyclical pattern is the key clue — and a real advantage, because a predictable trigger can be planned around. Keeping a simple diary that links your headaches to your cycle is the most powerful first step, both for you and for the doctor helping you find the right prevention or treatment.
Signs & symptoms
- A throbbing or pulsing headache, often on one side
- Headaches that reliably appear just before or during your period
- Nausea or vomiting during an attack
- Strong sensitivity to light, sound, or smells
- Pain severe enough to disrupt work or daily life
- Attacks that last longer and respond less well to usual painkillers
- Tiredness, irritability, or difficulty concentrating around the attack
Types
Pure menstrual migraine
Attacks happen only around the period — in the two days before or the first few days of bleeding — and at no other time of the cycle.
Menstrually-related migraine
Attacks cluster around the period but also occur at other times of the month. This is the more common pattern.
Migraine without aura
The usual form for menstrual attacks — head pain with nausea and light sensitivity, but without visual or sensory warning signs beforehand.
What causes it
- The natural drop in oestrogen just before a period
- Hormonal fluctuations across the menstrual cycle
- A personal or family history of migraine
- Skipping meals, dehydration, or poor sleep around your period
- Stress, which often peaks premenstrually
- The hormone-free week of some combined contraceptive pills
When to seek help
See a doctor if headaches regularly knock you out around your period, if usual painkillers aren't helping, or if you're reaching for pain relief on more days than not — frequent use can cause its own 'rebound' headaches. Seek urgent medical care for a sudden, severe 'thunderclap' headache, the worst headache of your life, or a headache with fever, a stiff neck, weakness, confusion, or vision loss. If you get migraine with aura, mention it before starting any oestrogen-containing contraception.

Frequently asked
Why do my migraines come with my period?
It's largely down to oestrogen. Levels fall sharply just before your period, and for some women that drop is a powerful migraine trigger — which is why attacks line up so reliably with the cycle.
Can the contraceptive pill make it better or worse?
It can do either. Some pills smooth out hormone swings and help; the hormone-free week of others can trigger attacks. Importantly, if you have migraine with aura, oestrogen-containing pills may not be safe, so always discuss this with a doctor.
Will it improve after menopause?
Often, yes. Because menstrual migraine is driven by cyclical hormone changes, attacks frequently settle once periods stop. The perimenopause transition itself can be bumpy first, as hormones fluctuate more.
Is it just a bad headache?
No — migraine is a neurological condition, not simply a strong headache. The throbbing pain, nausea, and light sensitivity can be genuinely disabling, and it deserves proper treatment rather than just pushing through.
