How to Track Migraines Across Your Cycle

To see whether your migraines follow your cycle, log each attack and each period day for at least three months. Mark the two days before and the first three days of bleeding, and look for a repeating pattern. Take the log to a doctor.

This guide is general information, not medical advice.

Why the cycle matters

Migraine is more common in women than men, and for many the attacks cluster around hormone changes. The drop in estrogen just before a period is a known trigger for some. Hormonal shifts in puberty, pregnancy, postpartum, and perimenopause can also change the pattern, improving it for some and worsening it for others.

Doctors sometimes describe two patterns:

• Menstrual migraine. Attacks happen only around the period, usually within 2 days before to 3 days after the first day of bleeding.
• Menstrually related migraine. Attacks happen around the period and also at other times.

Many women have the second type. Tracking tells you which one fits.

Menstrual attacks can be longer and harder to treat than others, which is part of why finding the pattern is worth it.

What to log

Keep it simple so you will actually do it. Each day, record:

1. Period. First day of bleeding, and each day it lasts. Mark spotting as well.
2. Headache or migraine. Yes or no, start time, how long it lasted.
3. Severity. 0 to 10.
4. Symptoms. Nausea, light or sound sensitivity, aura (flashing lights, blind spots, tingling), dizziness.
5. Medicine. What you took, the dose, the time, and whether it helped within two hours.
6. Possible triggers. Sleep, stress, skipped meals, alcohol, caffeine, weather, strong smells.
7. Hormonal factors. Birth control, missed pills, changes in treatment.
8. Impact. Did you miss work, school, or plans?

You do not need to log everything on bad days. Write the basics and add detail later.

A simple tracking table

Date	Cycle day	Period?	Migraine?	Severity 0-10	Aura?	Medicine and result	Notes
Mar 2	27	No	Yes	7	No	Ibuprofen at 9 am, helped some by 11	Slept 5 hours
Mar 3	28	No	Yes	8	No	Triptan at 7 am, gone by noon	Period due
Mar 4	1	Yes	No	0	No	None

Cycle day 1 is the first day of full bleeding. Counting from that day makes patterns visible across months.

Paper, app, or calendar

All work. What matters is that you will use it.

• Paper calendar. Color dots: red for period, purple for migraine. A pattern shows up in a glance.
• Notes app. Fast to open, easy to copy and share.
• Dedicated headache or cycle app. Often creates charts and doctor-friendly summaries. Check the privacy settings before entering personal data.
• Printed log. Good if you prefer not to use a phone in pain.

If you have trouble sticking with daily logging, how to use a habit tracker so it sticks has tricks that work for this too.

How to read your log after three months

Take a calendar for each month and highlight:

• The first day of each period
• Every migraine day

Then ask:

1. Do attacks fall in the window from 2 days before to 3 days after the first day of bleeding?
2. Does this happen in at least two out of three cycles?
3. Do other attacks happen outside that window?
4. Are the menstrual attacks more severe, longer, or less responsive to medicine?
5. Do attacks line up with the placebo or pill-free week if you use hormonal birth control?
6. Have things shifted recently, for example more frequent attacks in your 40s?

If the answer to the first two is yes, mention “possible menstrual migraine” to your doctor. It can shape treatment, since some strategies are timed around the predictable window.

Triggers beyond hormones

Hormones are rarely the whole story. Common triggers include:

• Irregular or too little sleep, or sleeping in
• Skipped meals or dehydration
• Alcohol, especially red wine
• Too much caffeine, or sudden withdrawal
• Stress, and the letdown after stress
• Bright or flickering light, strong smells
• Weather or pressure changes
• Some foods, although the evidence is mixed and often overstated

Your log can show your own pattern. If skipping lunch plus a late night always leads to an attack, that is useful to know. For ideas on steadier sleep, read how to sleep through perimenopause, which applies to anyone whose nights are shaky.

What your doctor might offer

This is a conversation, and options depend on your health, other medicines, and goals. Doctors may discuss:

• Acute treatments to use at the first sign of an attack, including over-the-counter pain relievers and prescription migraine-specific medicines
• Short-term preventive treatment around the predictable days
• Daily preventive medicines if attacks are frequent
• Adjustments to hormonal birth control, for example avoiding the hormone-free week
• Lifestyle plans for sleep, meals, and stress
• A referral to a headache specialist

Be careful with frequent use of pain relievers. Taking them more than a few days a week can lead to medication-overuse headache, which makes the problem worse. Your log will show how often you reach for them.

A note about birth control: migraine with aura is linked to a higher risk of stroke in people who take estrogen-containing contraceptives. If you have aura, tell your doctor before using or continuing one.

A checklist for your visit

• Three months of log data, printed or on your phone
• A short summary: how many attacks per month, how long, how bad
• How many fall around your period
• Every medicine you take, including birth control and supplements
• How often you take pain relief
• Family history of migraine
• Missed work or school days
• Your questions

Our guide on how to prepare for a doctor’s appointment in 10 minutes shows how to turn this into a short conversation.

When to see a doctor

Make an appointment if:

• Headaches are new, more frequent, or more severe
• Over-the-counter medicine no longer works
• You miss work, school, or plans because of attacks
• You are taking pain relievers on more than a few days a week
• You have aura and use or are considering estrogen-containing birth control
• Your pattern changes during perimenopause

Seek emergency care right away for:

• A sudden, severe “worst headache of your life”
• Headache with weakness on one side, trouble speaking, confusion, or vision loss that does not clear
• Headache with fever, stiff neck, or a rash
• Headache after a head injury
• A first-ever aura that lasts more than an hour, or any new neurological symptoms

If pain or mood is overwhelming and you have thoughts of harming yourself, call or text 988 in the US.

Making the log easier on bad days

Pain and nausea make tracking hard. Lower the effort. Use a single symbol for a migraine day on a wall calendar. Keep a pen by the bed. Ask a partner or friend to jot down times if you cannot. After the attack passes, fill in the details in two minutes. A few missing days will not ruin the pattern, so do not give up after a gap. Aim for most days, not every day.

A soft next step

If you would like a ready format for the log, the questions to ask, and a plan for the hormone-related days, Migraine and Hormones: Tracking and a Plan puts them together. It supports the conversation with your doctor, and it does not replace it.

The short version

Log every migraine and every period day for three months, noting severity, medicine, and triggers. Look for attacks in the window around the first day of bleeding. Bring the log to a doctor, mention aura and birth control, and ask about options timed to your pattern.
