- According to WHO, an estimated 10% (190 million) of reproductive age women worldwide have endometriosis, and severe period pain, heavy bleeding, and chronic pelvic pain are among its symptoms (WHO).
- NICE directs clinicians to tell people with suspected or confirmed endometriosis that a pain and symptom diary can aid discussions (NICE NG73).
- In a one-week study of 28 patients, ratings made at the end of the week ran higher than the average of in-the-moment ratings and showed peak reporting (van Barneveld et al., 2023).
- Endometriosis Journey keeps flare marks, daily check-ins, period dates, and medicine times in one dated history, so each flare can be read against the days around it.
A flare is easiest to describe on the day it happens. A week later the rating has drifted, the order of events has blurred, and the note has shrunk to "it was bad." A same-day entry keeps the number, the place, the timing, and what the day had to change.
This guide explains how to log an endometriosis flare the same day it happens. It covers what a two-minute entry holds, how to describe pain type, place, and timing, which cycle and body context to add, what to write when pain limits typing, how to mark a late entry, how to read a month of flares, how to bring them to a visit, and which signs call for urgent help instead of a log entry. Here a flare means a day clearly worse than your usual symptom level.
Why a same-day entry records more than a memory of the endometriosis flare
Memory rounds a flare toward its worst moment. In a one-week study of 28 patients with endometriosis, end-of-week pain scores were higher than the mean of scores taken in the moment, and the authors described the difference as peak reporting (van Barneveld et al., 2023). A rating written on the day keeps that day's level, so it can be compared with the other days of the month.
Diary research rests on the same idea. The daily Endometriosis Pain and Bleeding Diary used a 24-hour reference period, chosen to minimize recall bias and because focus group participants said their symptoms vary daily. In the 128-person validation study, the compliance rate for completing the electronic diary was 90% (Deal et al., 2010).
A same-day entry also keeps the details that fade first: the hour the pain began, what you were doing, and which plans changed.
In Endometriosis Journey (by Health Journey Labs), the Flare Tracker labels a day that was clearly harder than your usual and stores the onset, the intensity, and a short note. The Daily check-in adds pelvic pain, fatigue, bowel or bladder symptoms, and the work or plans you limited, so the flare mark has a baseline around it. Placing the two in one history shows whether a flare was a one-off spike or part of a repeating pattern.
What to write in a two-minute endometriosis flare entry
A flare entry works when it is short enough to finish while the pain is present. The fields below take about two minutes. The diary studies above rated pain from 0 to 10, where 0 is no pain and 10 is the worst pain imaginable, and one fixed scale keeps entries comparable.
Table for a two-minute flare entry, by Endometriosis Journey
| Field | What to write | Example |
|---|---|---|
| Start | The clock time the flare began | "Began 2:40 pm" |
| Pain now and worst | Two ratings from 0 to 10 | "Now 6, worst 8" |
| Type and place | One or two words for each | "Sharp, lower left; dull ache, back" |
| Bleeding | Whether you are bleeding, and how heavy | "Day 2, pad every 3 hours" |
| Other symptoms | Bowel, bladder, nausea, fatigue | "Painful bowel movement at noon" |
| What changed | The plan or task you stopped or moved | "Left work early" |
| What you took | Medicine and time, as directed | "Taken at 3:00 pm" |
From Endometriosis Journey, we recommend filling in only what you can while the pain is present and adding detail after it eases. Use the same scale every time, so a 7 today means what it meant last month.
With Endometriosis Journey, the Daily check-in walks through physical symptoms, mood, sleep, movement, and medicines in one guided pass, and Custom symptoms add a label for a pain you describe in your own words. Because the questions repeat daily, a flare day can be compared with a lower-symptom day. After a few weeks, the pattern shows how far flare days differ from your usual level.
How to describe endometriosis flare pain: type, place, and timing
Pain has a type, a place, and a time course, and a clinician hears each one differently. In the Endometriosis Pain and Bleeding Diary work, focus group participants described two kinds of pain. Intermittent pain was sudden and "sharp shooting," while continuous pain was a "dull ache" or "aching" and lasted longer (Deal et al., 2010). The NHS pelvic pain page adds more words: a sharp, stabbing or burning pain that happens suddenly, a dull or heavy ache or feeling of pressure, and a cramping or throbbing pain that may come and go (NHS).
Write the words you would say out loud, then add three facts.
Pain type, place and timing
Endometriosis Journey records where the pain is and how it behaves.
- Place: lower abdomen, one side or both, lower back, rectum, or elsewhere.
- Pattern: constant, in waves, or only with movement, a bowel movement, urinating, or sex.
- Time course: when it began, when it peaked, and when it eased, even by a rough clock time.
NICE lists deep pain during or after sex and painful bowel movements among the symptoms that should make a clinician suspect endometriosis (NICE NG73), so record them when they occur, for example "pain with a bowel movement, 1 of 3 times."
The Daily Journal in Endometriosis Journey takes free-text notes and voice entries, so "sharp, then a dull ache" is stored in your own words. It also holds the sentence about what the flare limited, which a number cannot carry. Over several flares, the pattern in your wording shows whether the pain keeps its character or changes between episodes.
Which endometriosis context to log the same day: cycle day, bleeding, bowel and bladder, and medicines
Context fields turn a pain rating into something a clinician can interpret. Count the cycle day from the first day of bleeding, so day 1 is the first day of the period. Then add the other fields that guidance points to. NICE also names period-related or cyclical urinary symptoms, in particular blood in the urine or pain passing urine (NICE NG73), so bladder changes belong in the entry with the pain. The NHS describes heavy periods as needing to change pads or tampons every 1 to 2 hours, or bleeding through to clothes (NHS).
Context on each cycle day
Endometriosis Journey notes this context on the same day as the pain.
| Context | What to write | Why a clinician asks |
|---|---|---|
| Cycle day | Day number, or days since the last period began | Shows whether flares follow the bleeding days or fall outside them |
| Bleeding | Light, moderate, or heavy; how often you changed products | Gives the heaviness in a countable form |
| Bowel and bladder | Pain, urgency, or changes during the flare | Separates pelvic pain from bowel or bladder causes |
| Medicines | Name, time taken, and how the next hours went | Records what was tried and when |
| Sleep the night before | Hours and wake-ups | Adds a factor that can shift the next day |
Record medicines as your prescriber directed and write only what you took. The guide on tracking endometriosis medicines against pain and bleed weeks covers the medicine log in more detail.
In Endometriosis Journey, the Period Tracker records when each period begins and ends and whether the bleeding felt heavy or light, so the cycle day on a flare entry comes from dated records. My Meds holds the names, timing, and dose of the medicines you take, including pain options you already use as directed, which links the time you took something to the pain rating that followed. After a few cycles, the pattern shows whether flares gather in the bleeding days, the days before, or the days between.
What to write when endometriosis pain is too strong for a full entry, and how to add a late one
Some flares leave room for one line, and a short entry still counts. The minimum is three items: the time it began, a rating from 0 to 10, and one word for the type. The rest can be added later in the day.
When an entry cannot be made on the day, write it as soon as you can and mark it late. Use the flare's date, add "written later" to the first line, and label the rating you remember as an estimate. If the rating is gone, record the facts you do remember, such as the plans that changed and the medicine you took, and leave the rating blank.
A voice note works when typing hurts: say the time, the rating, the type, and what changed.
In Endometriosis Journey, the Flare Tracker asks for a flare day's onset, intensity, and a short note, which is already a small entry. Weekly Goals holds one small aim, such as logging the next flare on the day it starts, and records whether the aim held. Across several weeks, the habit shows how many flares were logged on the day and how many were added later.
How to read a month of endometriosis flare entries
One flare is an event. A month of flares is data. Read the month once, in a table, after the cycle ends.
Table for a monthly flare review, by Endometriosis Journey
| Flare | Cycle day | Peak rating | Hours | What it limited |
|---|---|---|---|---|
| Flare 1 | Day 2 | 8 | 6 | Left work early |
| Flare 2 | Day 17 | 6 | 4 | Canceled an evening plan |
The values above show the format. Then ask your own table four questions. Do flares cluster in the bleeding days, the days before, or between periods? Do peak ratings rise or fall from one cycle to the next? Do the long flares share a factor, such as a poor night or a bowel symptom? What did they stop you from doing?
Two or three cycles can show a pattern. The table names no cause, and your clinician reads it together with your exam and tests.
The Flare Tracker in Endometriosis Journey lines each flare mark up with the weeks around it, which separates a one-off spike from a repeating pattern. Learn offers short education topics on cycle pain, fatigue, and pacing that you can read with your own logged weeks. Over months, the pattern shows whether flares are becoming more frequent, longer, or more tied to the cycle.
How to bring endometriosis flare entries to a doctor
A visit is short, so bring a summary and keep the entries as backup. NICE advises referral to a gynecology service when symptoms of endometriosis have a detrimental impact on activities of daily living or are persistent or recurrent (NICE NG73). Flare entries that record what each flare limited and how often flares recur match those descriptions.
Flare records list for a doctor, by Endometriosis Journey
- The span you cover, for example the last two cycles.
- The number of flares, with the cycle day, peak rating, and length of each.
- What the flares stopped you from doing, by date.
- Medicines taken as directed, with times and what followed.
- Bowel, bladder, or bleeding changes that came with the flares.
Bring these as one short page (Endometriosis Journey checklist) with three written questions, such as: Does this pattern change what you want to check? Which flare features should I report between visits? What should I add to my log? Open with a one-sentence headline, for example "I had four flares in two cycles, and three began in the days before bleeding." For a longer plan, see preparing for a short endometriosis doctor visit.
For a visit, the Doctor Report in Endometriosis Journey builds one page from your logged history, covering dated flares, cycle timing, and what each one limited. My Care Team keeps clinician names and short visit notes, so you can prepare what to ask and review the answers afterward. The pattern across visits shows which questions were answered and which keep returning.
Signs during a flare of endometriosis that need urgent help instead of a log entry
Some pelvic pain needs care before it needs a record. The NHS page on pelvic pain says to seek immediate help when pelvic pain is severe, getting worse, or hurts when you move or touch the area, or comes with feeling faint, dizzy, or lightheaded, passing out, pain in the tip of the shoulder, difficulty breathing, heavy vaginal bleeding, or sudden confusion (NHS). With any of these, contact your local emergency services right away (for example, 911 in the United States).
The same page lists signs that call for urgent attention from a clinician: difficulty urinating or having a bowel movement, blood in urine or stool, unusual discharge or vaginal bleeding, pain when urinating or needing to urinate more than usual, a very high temperature or feeling hot, cold, or shivery, vomiting and diarrhea or feeling sick, or being pregnant or possibly pregnant. Contact your clinician or a local urgent-care service for these.
Help comes first. The entry can be added afterward, marked late, with the time the sign began. A flare that feels different from your usual ones is also worth reporting to a clinician.
After you have help, the Daily Journal in Endometriosis Journey takes a voice entry or a few typed lines about when the sign began and what was done. The saved account gives the clinician the order of events without relying on memory. Across the history, the entry stands out as a change from your usual flare pattern.
How Endometriosis Journey can help
A notebook or a phone note holds a flare entry well. Over several cycles, flare notes, period dates, and medicine times end up in different places. A tracker that keeps them in one dated history makes the month easier to read. You can compare options in Best Endometriosis Apps 2026.
Endometriosis Journey is a personal endometriosis tracker from Health Journey Labs on the App Store and Google Play. It lets you mark a flare with its onset, intensity, and a short note on the day, and read it with the check-in, period dates, and medicine times for the same days. Across cycles, the history shows how often flares come, where they fall in the cycle, and what each one limited. Below is what you can use and how each part helps.
- Daily check-in — A guided daily pass over symptoms, mood, food, sleep, movement, medicines, and outside factors, with room for pelvic pain, fatigue, bowel or bladder symptoms, and plans you changed.
- Daily Journal — Typed or spoken notes on what the day limited, partner talks, fertility questions, visit debriefs, or guilt after canceling.
- Flare Tracker — Marks a day that was clearly harder than your usual, with onset, intensity, and a short note, so later weeks show a single spike or a repeating pattern.
- My Meds — Medicine names, timing, and dose, including pain options you already use as directed, lined up with pain weeks, energy, and sleep.
- My Labs — Dates for imaging, bloodwork, and other tests, read against pain and function.
- Weekly Goals — One small aim for the week and a note on whether it held.
- Learn — Short topics and prompts on cycle pain, fatigue, pacing, and visit prep, tied to your logged weeks.
- AI companions — Clara for general questions and specialist companions for narrower ones, both with your logged history in view.
- My Care Team — Your clinicians and short visit notes, for preparing questions, noting answers during the visit, and reviewing afterward.
- Doctor Report — One page built from your logged history: dated flares, pelvic pain, cycle timing, and daily function.
- My Assessments — Structured check-ins beyond the daily scores, plus onboarding questions about your life and social context.
- Food Tracker — Meal and drink lines, compared with pain, energy, bowel symptoms, and flares.
- Period Tracker — Period start and end dates, flow, and bleeding that felt heavy or light, compared with pelvic pain, energy, and bowel symptoms.
- Weight Tracker — Scale or body notes, compared with energy, sleep, and pain.
Everything you log builds one history, and insights get stronger as it grows. Custom symptoms let you add your own labels.

FAQ
The answers below draw on the sources cited in this guide, and the app they mention is Endometriosis Journey (by Health Journey Labs).
How soon after a flare starts should I write it down?
Within the same day is the target, and the first line can go in as soon as you can hold a phone for a minute. Start with the clock time and a 0 to 10 rating, then add the rest when the pain allows.
In Endometriosis Journey, the Flare Tracker takes the onset, intensity, and a short note, and the Daily check-in can be finished in the evening. The history then shows how many flares were logged on the day and how many were added later.
What is the least I can log when a flare hurts too much to type?
Three items are enough: the time the flare began, a rating from 0 to 10, and one word for the type of pain. If typing hurts, say them aloud as a voice note.
With Endometriosis Journey, the Daily Journal accepts a voice entry, and the Flare Tracker keeps a short note with onset and intensity. Over several cycles, these dated points show when flares tend to start.
Should I log only flare days, or every day?
Both help. A flare means a day clearly worse than your usual level, and that level is only visible if ordinary days are logged too. An ordinary-day entry takes under a minute and gives each flare a baseline.
In Endometriosis Journey, the Daily check-in covers every day and the Flare Tracker marks the outliers. Insights can then compare flare days with the other days around them, which shows whether poor sleep, bowel symptoms, or bleeding days tend to come first.
Which pain rating should I give a flare?
Give two ratings from 0 to 10, one for the pain now and one for its worst point, where 0 is no pain and 10 is the worst pain imaginable. Keep the anchors the same every time, so a 7 in March matches a 7 in June.
With Endometriosis Journey, the Flare Tracker stores the intensity on the day, and the weeks of entries show the direction of the peaks. A rise or fall across cycles gives your clinician a clearer picture than one remembered score.
How do I tell a flare from an ordinary hard period day?
Compare the day with your own usual level. If a period day is as hard as earlier period days, log it as a period day. If it is clearly worse, or hard in a different way, flag it as a flare and write what differed.
In Endometriosis Journey, the Period Tracker keeps the bleeding dates and the Flare Tracker keeps the flagged days. Read together, they show whether your flares mostly fall on bleeding days, which describes what a hard period day means for you.
Which cycle day should I write for a flare?
Count day 1 as the first day of bleeding and number each day forward. If the flare comes before the next period, write the count so far, such as "day 27, period not started."
With Endometriosis Journey, the Period Tracker stores when each period started and stopped, so the day count comes from dated records. After a few cycles, the history shows whether flares gather early in the cycle, late in it, or without a clear link.
What if I forget to log a flare and remember days later?
Add it under the date the flare happened, write "written later" on the first line, and give the rating as an estimate. If the rating is gone, record the facts you know and leave the rating blank.
In Endometriosis Journey, the Daily Journal holds a note written later, and a Weekly Goals aim of logging flares on the day gives the habit a target. The history then separates flares logged on the day from flares reconstructed afterward, so each number carries the right weight.
Is a voice note acceptable instead of typing during a flare?
Yes. A spoken entry carries the same facts as a typed one. Say the time, the rating, the type and place of the pain, and one sentence about what changed in your day.
With Endometriosis Journey, the Daily Journal takes voice entries, so the words you used while the flare was active stay as you said them. Reading them across flares shows whether you describe the pain the same way each time.
Should I log what I ate before a flare?
Log meals on flare days and the days around them, and treat what you see as a candidate, not a cause. Changes to eating belong with a clinician or dietitian.
In Endometriosis Journey, the Food Tracker takes meal and drink lines that can be compared with pain, energy, bowel symptoms, and flares. After a few cycles, the history shows whether the same food appears before several flares or before only one.
How do I log bowel and bladder symptoms during a flare?
Write what happened in plain words with a time: pain with a bowel movement, urgency, loose or hard stools, pain passing urine, or needing to go more often. Blood in urine or stool calls for prompt advice from a clinician.
With Endometriosis Journey, the Daily check-in includes bowel or bladder symptoms, so they land in the same entry as the pelvic pain rating. The history then shows whether these symptoms arrive with flares, come on separate days, or follow the cycle.
Should I log the medicine I took and whether it helped?
Yes. Write the medicine name and the time you took it, as your prescriber directed, and add your pain rating again later in the day. The log records what happened and leaves any medicine change to your prescriber.
In Endometriosis Journey, My Meds holds the medicine name, timing, and dose, and the Flare Tracker holds the ratings. Lining the two up shows how the hours after a medicine went across several flares, which gives the prescriber a record to review.
Could logging a flare keep me focused on it?
It can, for some people. Keep each flare entry to the two-minute fields, do the daily check-in at one fixed time, and stop there. If logging raises your distress or worry about pain, shorten the log and tell your clinician.
With Endometriosis Journey, Weekly Goals lets you set one small aim, such as one entry per flare, and note whether it held. The Daily check-in also records days without a flare, so the history shows both kinds of day.
Do I need several months of flare entries before a clinician can use them?
No. Bring what you have. Even one or two weeks of dated entries give a clinician specifics to ask about, and a visit should not wait for a longer record.
In Endometriosis Journey, the Doctor Report pulls whatever span of history exists into one page and grows as you log. A summary built after two weeks and one built after six months read the same way, so the later page shows what changed.
How do I share flare entries with a partner or family member?
Share a short summary rather than the whole log: how many flares you had, what a flare looks like, what you can and cannot do during one, and one specific request. The guide on explaining an endometriosis flare to a partner gives more wording.
With Endometriosis Journey, the Daily Journal holds your own debriefs, and the AI companions, including Clara, already see your logged history and can help you draft a short script. The record then supports a conversation about the past month.
What privacy steps make sense for a health log?
Bleeding, pain during sex and fertility notes are personal, and partners, parents or coworkers may share a device with you. Use a screen lock, keep the log off family tablets, and choose which entries go to the gynecology visit.
Entries you add to Endometriosis Journey are your own health notes. Check the app's privacy policy for how data is stored and handled. Nothing in this article is medical advice.
