At a glance
- A narrative review of 22 studies concluded that a subset of women with bipolar disorder are vulnerable to the impact of menstrual cycle events, and that the pattern of mood variability is unclear (Aragno et al., 2022).
- Write the cycle day on every entry, counted from day 1, the first day of the period, so each mood and sleep rating has a place in the cycle.
- NIMH advises keeping a life chart or mood journal to help recognize mood swings, and two or three cycles of daily entries make the comparison.
- Bipolar Journey is a bipolar tracker that keeps period dates, sleep hours, mood ratings, and notes in one dated history, with Insights across weeks.
Some people with bipolar disorder notice that mood, energy, or sleep shift at the same point of the menstrual cycle, month after month. Others see steady ratings all month. Research on the question is mixed, so a dated record is more useful than a guess: after two or three cycles, the record shows which description fits.
This guide covers what the research reports, how to count cycle days, the daily fields to log, sleep across the cycle, how to compare a cycle pattern with a mood episode, what to do when cycles are irregular, and what to bring to a visit. It works from your own cycle days and ratings.
What research reports about the menstrual cycle and bipolar mood
A systematic review of case reports and studies identified 25 case reports, ten retrospective studies, and 11 prospective studies. Menstrual cycle-related mood changes were reported by 64-68% of women with bipolar disorder in retrospective studies and were displayed by 44-65% of women in prospective studies (Teatero et al., 2014). The reviewers concluded that a subgroup of women with bipolar disorder, possibly those with hormonal sensitivity, experience menstrual cycle effects on depressive, hypomanic, and manic episodes.
In the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), 293 premenopause-age women were followed prospectively for one year. Of these, 191 women (65.2%) had premenstrual exacerbation, and that group had more mood episodes, primarily depressive, than the 102 women without it (Dias et al., 2011).
The findings vary. A small prospective study that assessed women across three menstrual cycles found mood symptom level, psychosocial functioning, perceived stress, and physical discomfort were unrelated to menstrual phase (Sit et al., 2011). A log answers the question for one person by showing whether the same cycle days bring the same change month after month.
Three questions guide the entries:
- Does a change appear on the same cycle days in two or more cycles?
- Is the change toward lower mood, higher mood, or both?
- Does sleep shift before the mood does?
In Bipolar Journey (by Health Journey Labs), the Period Tracker keeps the start and stop dates of each period, which fixes day 1 for every cycle. The Daily check-in records sleep, mood, and energy on each date. Insights then lines up the cycle weeks with the sleep and mood ratings, so the three questions above can be answered from the dated history.
Counting cycle days from day 1 in a mood log with bipolar disorder
The Office on Women's Health explains that a menstrual cycle begins with the first day of the period and starts over again when the next period begins, and that periods are still regular if they usually come every 24 to 38 days. Day 1 is therefore the first day of bleeding, and every later entry gets a number from there.
The research describes different timing for different people. A subgroup shows premenstrual exacerbation of depressive symptoms, while others report premenstrual or periovulatory exacerbation of hypomanic or manic symptoms (Kuehner and Nayman, 2021). A log that covers the whole cycle can show which timing applies. Ovulation is hard to place by calendar alone, because the time between ovulation and the next period can be anywhere from 7 to 19 days, according to the Office on Women's Health.
A simple labeling scheme avoids guessing. Write two numbers on each entry: the cycle day counted forward from day 1, and the days before the next period, filled in afterward once that period starts.
Cycle day labels
Bipolar Journey counts cycle days from day 1.
| Part of the cycle | How to label it | What to add |
|---|---|---|
| Bleeding days | Cycle day 1, 2, 3, and so on | Flow, cramps, energy |
| Middle of the cycle | Cycle day number, plus any ovulation sign you already track | Sleep need, speed of thoughts, energy |
| Days before the next period | 7 days before, 6 days before, and so on, added afterward | Low mood, irritability, sleep hours |
The Period Tracker in Bipolar Journey stores the start date of each period, so the cycle day and the days before the next period can be read from the dates. The Daily Journal holds an ovulation sign or a note about the middle of the cycle in your own words. Insights compares the sleep and mood entries from the bleeding days, the middle days, and the days before the next period.
Daily bipolar mood fields across the cycle: low mood, high mood, energy and irritability
NIMH advises keeping a life chart or mood journal to help recognize your mood swings.
Bipolar mood moves in two directions, so one number hides mixed days. Rate low mood and high mood separately from 0 to 3, then add energy and irritability. For why one mood score leaves out information, see what to log between hard weeks beyond one mood score.
From Bipolar Journey, we recommend rating low mood and high mood on separate lines for the first month, because the separate lines show mixed days. A one-minute entry covers these fields:
Daily low mood, high mood, energy and irritability
Bipolar Journey rates these four fields every day.
| Field | How to record it | Example |
|---|---|---|
| Cycle day | Number from day 1 | Day 23 |
| Low mood | 0 to 3 | 2 |
| High mood | 0 to 3 | 0 |
| Energy | 0 to 3 | 1 |
| Irritability | 0 to 3 | 3 |
| Physical symptoms | Cramps, headache, breast tenderness, bloating: yes or no | Cramps |
| One line | What stood out today | Snapped at a coworker, felt sorry by noon |
Use the same scale anchors every day, so a 2 in week one means what a 2 means in week four. To set up the habit first, see starting a sleep and mood log.
The Daily check-in in Bipolar Journey covers emotional state, sleep, and physical symptoms in one pass, and custom symptoms hold separate low mood, high mood, and irritability lines. The Daily Journal carries the one-line note, in text or by voice. My Assessments adds structured check-ins that give Insights more context about your life. Together they turn the 0 to 3 ratings into a record that Insights can compare cycle day by cycle day.
Sleep across the menstrual cycle with bipolar disorder: bedtime, hours and sleep need
A study of 727 women compared biological rhythms in women with bipolar disorder, premenstrual dysphoric disorder, or both, and in controls. Women with bipolar disorder presented greater overall biological rhythm disruption, and greater disruption in sleep, activity, and eating patterns, than women with premenstrual dysphoric disorder (El Dahr et al., 2022). Sleep, activity, and meals are the rhythm fields to place on the cycle calendar.
Two sleep measures need separate lines. Hours slept is the number. Sleep need is how rested or wired the morning felt. A short night followed by high energy is a different entry from a short night followed by exhaustion, and the difference is useful to bring to a prescriber.
NIMH lists decreased need for sleep among the symptoms of a manic episode, and trouble falling asleep, waking up too early, or sleeping too much among the symptoms of a depressive episode. Use this quick set each morning:
Sleep across the cycle
Bipolar Journey records bedtime and wake time as clock times.
- Bedtime and wake time: the clock times, even if you did not sleep the whole span.
- Hours slept: your best estimate in whole or half hours.
- Morning state: rested, tired, or wired.
- Routine changes: meal times, activity, travel.
For the next-day effect of short nights, see how short sleep affects next-day mood.
In Bipolar Journey, the Daily check-in keeps sleep hours and mood on the same date, and the Food Tracker holds meal, caffeine, or alcohol lines that change the sleep routine. A late coffee and a short night then appear under one date. Insights then compares the nights in the final days before a period with the nights in the middle of the cycle.
Telling a cycle pattern from a bipolar mood episode: two months of charting
A systematic review of premenstrual dysphoric disorder and bipolar disorder noted that the available studies failed to employ prospective monitoring of symptoms, perhaps the most important feature necessary for confirming premenstrual dysphoric disorder and differentiating it from premenstrual exacerbation of bipolar disorder (Sharma et al., 2022).
Kuehner and Nayman state that the Canadian Network for Mood and Anxiety Treatments (CANMAT) guidelines require, for an accurate diagnosis of comorbid premenstrual dysphoric disorder in women with bipolar disorder, a stable state of euthymia during the remaining cycle phases and a minimum of 2 months of prospective pre- and postmenstrual symptom charting.
NIMH describes mood episodes as symptoms that last a week or two, or sometimes longer, every day for most of the day. A cycle pattern differs in timing: it begins and ends around the same cycle days. Compare cycles in a grid:
A cycle pattern or a mood episode?
Bipolar Journey compares two months of charting to tell them apart.
| Cycle | Days before period: low mood (0 to 3) | Days before period: sleep hours | Mid-cycle: high mood (0 to 3) | Rest of cycle: low mood |
|---|---|---|---|---|
| Cycle 1 (example) | 2 to 3 | 5 | 0 | 0 to 1 |
| Cycle 2 (example) | 2 | 5.5 | 1 | 0 to 1 |
| Cycle 3 (example) | 3 | 5 | 0 | 1 |
The values above are illustrative. The same window repeating across cycles supports a cycle pattern. Symptoms that continue through the whole cycle belong in the episode record, and a clinician can read both.
Bipolar Journey keeps the period dates in the Period Tracker and the daily ratings in the Daily check-in, which gives each cycle its own row of dated numbers. The Flare Tracker marks a day clearly worse than your usual hard week, so a mood spike has its own dated mark. Insights then separates a one-off spike from a rating that repeats in the same window each cycle.
Irregular cycles, skipped periods and life changes in a mood log with bipolar disorder
Cycle length can differ from month to month, and the research notes a gap: most studies in bipolar disorder excluded women with menstrual cycle irregularities, which substantially limits generalization (Kuehner and Nayman).
Keep the day count running even when the cycle is longer than expected. If the next period has not started, continue the numbering from the last day 1 (day 40, day 41, and so on) and flag the entry as a late period. When the period does start, restart at day 1 and fill in the days-before label for the long cycle.
Note events that can move a cycle or a mood in the same weeks, so the chart gives the cycle credit only for what the cycle explains:
Irregular cycles and changes during the log
Bipolar Journey marks events that can shift the cycle or mood.
| Event | What to write |
|---|---|
| Late or skipped period | Day count, flag, and the date of the next period |
| Travel or time zone change | Dates, direction, nights of lost sleep |
| Illness or poor sleep stretch | Dates and how long it lasted |
| A change to a prescribed medicine | Date, who advised it, and the reason you were given |
| A major stress | Date and a few words |
The Office on Women's Health advises talking to a doctor or nurse about cycles longer than 38 days or shorter than 24 days.
The Period Tracker in Bipolar Journey takes each start date as it happens, so a late period shows as a longer gap between dates. My Meds records medicine names and timing as prescribed, including the date of any change, and the Daily Journal holds the travel, illness, or stress line. Insights then compares the long cycles and the usual cycles against the same sleep and mood fields.
What to bring to a visit about cycle-linked bipolar mood changes
Two or three cycles of entries fit on one page. Bring the grid from the previous section, a list of the dates of the last three periods, and three or four example weeks where a rating changed. Write the question you most want answered at the top of the page.
Take the same page to the clinician who manages your bipolar care. If periods, bleeding, or cycle length are also a concern, a primary care clinician or a gynecologist can use the same dates. Questions to bring:
Questions about cycle-linked mood changes
Bipolar Journey asks whether the chart shows a repeating pattern.
- Does the timing on my chart look like a repeating pattern to you?
- Which days should I mark more closely over the next cycle?
- Which signs should I report to you right away?
If low mood brings thoughts of self-harm, contact your care team the same day, and in an emergency call your local emergency number (911 in the United States). In the United States, you can also call or text 988. Write the entry afterward, once you are safe.
The Doctor Report in Bipolar Journey exports a one-page summary from your logged history, with period dates, sleep, and mood on the same page. My Care Team holds your clinicians and visit notes, so the questions above go in before the visit and the answers go in after. Insights gives the summary its cycle-by-cycle comparison, which makes the visit start from dated rows.
How Bipolar Journey can help
A paper calendar works for this log when each day has the same boxes: cycle day, low mood, high mood, sleep hours, and a one-line note. An app adds the comparison of one cycle against the next and keeps the grid current. For a comparison of trackers, see Best Bipolar Apps 2026.
Bipolar Journey is a personal bipolar tracker from Health Journey Labs on the App Store and Google Play. On this angle, it lets you record period dates, cycle days, sleep hours, separate low and high mood ratings, and a daily note on one dated timeline, with a medicine list kept as prescribed. Setting two or three cycles of entries side by side gives you and your clinician a specific account of which days repeat and which differ, which a memory of last month cannot supply. Below is what you can use and how each part helps.
- Daily check-in — A short guided pass across symptoms, mood, nutrition, sleep, exercise, and meds, so insights can show links memory misses.
- Daily Journal — Freer notes, including voice when typing is hard, that give insights context scores cannot carry.
- Flare Tracker — Mark a day clearly worse than usual, so insights can separate a one-off spike from a repeating pattern.
- My Meds — Medicine names and timing, including options you already take as prescribed. Insights can relate timing to sleep hours and next-day mood.
- My Assessments — Structured check-ins that give insights more context about your life.
- Learn — Short education topics on bipolar themes such as sleep, mood, routines, and visit prep.
- AI companions — Clara and specialist companions answer with your logged history in view.
- Weekly Goals — Set one small aim and see whether it held, which shows whether a habit change helped.
- Doctor Report — Export a one-page summary from your logged history when a written summary helps a short visit.
- My Care Team — Add clinicians and visit notes to prepare questions and review answers.
- My Labs — Result dates for ordered tests, weighed against sleep, mood, and function in the same weeks.
- Period Tracker — Start and stop dates, flow, and how heavy bleeding felt, so insights can relate each cycle to sleep hours and mood ratings across the weeks you logged.
- Food Tracker — Meal or drink lines, so insights can relate food, caffeine, or alcohol to sleep and mood.
- Weight Tracker — Scale notes when weight is part of what you and your clinician are watching, joined to the same sleep and mood history.
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 Bipolar Journey (by Health Journey Labs).
Can the menstrual cycle change bipolar mood?
For some people it appears to. A systematic review of prospective studies found a different pattern of symptom exacerbation in bipolar disorder than in other conditions, with mixed evidence overall and a possible subgroup who are sensitive to hormonal fluctuation (Nolan and Hughes, 2022).
A dated record is the way to find out for one person. In Bipolar Journey, the Period Tracker and the Daily check-in put period dates and mood ratings on one timeline, so you can see whether your own entries repeat by cycle day.
Which cycle days should I log?
Every day, including days that feel ordinary. Entries from the middle weeks are the baseline that makes the days before the period readable, and one minute per entry is enough.
In Bipolar Journey, the Daily check-in takes the same fields every day, and the cycle day comes from the Period Tracker dates. A full month of entries means no cycle window is missing when you compare.
How is premenstrual dysphoric disorder different from a premenstrual worsening of bipolar mood?
Premenstrual dysphoric disorder is a separate diagnosis, and the two can occur together. A systematic review of five studies found that the proportion of people with premenstrual dysphoric disorder who were diagnosed with bipolar disorder ranged from 10% to 15%, and that the proportion of people with bipolar disorder who received a premenstrual dysphoric disorder diagnosis ranged from 27% to 76% (Sharma et al., 2022).
The wide range shows how much depends on how symptoms are monitored. With Bipolar Journey, the Daily check-in gives you the prospective daily ratings, and a clinician can read them to sort out which label fits.
How many cycles do I need to log before it means anything?
ACOG advises writing down and rating symptoms each day for at least 2 to 3 months, and recording the dates of your periods as well. That advice is written for premenstrual syndrome, and it fits this question too.
Bipolar Journey keeps each cycle as its own run of dated entries, so after two or three cycles you can compare them side by side. Insights then shows whether the same window carries the same ratings.
Does a cycle log help if I am in perimenopause or my periods have stopped?
It can. A narrative review noted that menopause appears to be a period of vulnerability to mood alteration, especially depressive episodes, and a potential trigger of bipolar illness onset (Aragno et al., 2022). A mood and sleep log still works, and the day count can be replaced by calendar weeks.
In Bipolar Journey, the Daily check-in keeps sleep and mood on dated entries when period dates are absent, and the Daily Journal holds notes on hot flashes or irregular bleeding. A clinician can see the timeline across months.
My mood follows my cycle some months and not others. Is that a pattern?
Mixed months are consistent with the research. Several prospective small-scale studies and case reports failed to find consistent links between bipolar disorder and the menstrual cycle, indicating that not all women with bipolar disorder experience premenstrual exacerbation (Kuehner and Nayman). Keep logging and count the months that match.
The cycle-by-cycle grid works with partial matches. In Bipolar Journey, the Flare Tracker marks the hard days, and the Period Tracker shows where they fall, so after several cycles the share of matching months is visible.
I feel wired for a few days before my period. What do I write?
Write the cycle day, the sleep hours, and whether you felt rested after the short sleep. Add the speed of your thoughts, your energy from 0 to 3, and any spending, plans, or talk that went beyond your usual. A short night with no tiredness is the key detail.
With Bipolar Journey, the Daily check-in holds these ratings and the Daily Journal holds the plans or spending line. If wired nights repeat, contact your prescriber's office, and the dated entries show how many nights and which cycle days.
Should I log cramps, headaches, and breast tenderness too?
Yes, as a yes or no per day, because dated physical symptoms give each mood rating more context. The Office on Women's Health also suggests noting how heavy bleeding was and whether symptoms caused you to miss work or school.
The Daily check-in in Bipolar Journey includes physical symptoms with mood and sleep, and the Period Tracker holds flow. That gives the visit page one view of body and mood.
How do I log a medicine change that falls in the middle of a cycle?
Write the date, who advised it, and the reason you were given, then keep the same daily fields going. In the small prospective study, the authors concluded that appropriate maintenance treatment may prevent menstrual related mood symptoms (Sit et al., 2011), so the prescriber is the right person to ask about timing.
My Meds in Bipolar Journey dates the change as prescribed, and the Daily check-in keeps sleep and mood on the same timeline. The weeks before and after the change are then easy to compare.
Do I log in months when I feel stable?
Yes. Stable months are the comparison weeks. A rating of 1 before the period in a stable month tells the clinician the usual range, so a 3 in another month has a reference.
In Bipolar Journey, the Daily check-in keeps every month in one history, and Insights gets more useful as the number of cycles grows. Stable cycles and hard cycles sit in the same record.
Who should I show the cycle chart to?
Start with the clinician who manages your bipolar care, since mood and sleep are the main content. Add a primary care clinician or a gynecologist if bleeding, pain, or cycle length is also a question, and give each the same page so every clinician works from the same dates and ratings.
The Doctor Report in Bipolar Journey exports a one-page summary of your logged history, and My Care Team keeps each clinician's visit notes. One record then serves every appointment, and each visit adds to the same timeline.
What if my mood drops sharply before my period?
Log the day with a rating and a few words, and tell your care team the same day if the drop continues or worsens. If you have thoughts of self-harm, call your local emergency number, or call or text 988 if you are in the United States.
After you are safe, the Daily Journal in Bipolar Journey lets you record what happened in text or by voice. That account helps your care team plan the next step with you.
Do I need a separate period app?
One log is easier to compare than two. Keeping period dates in the same record as sleep and mood avoids copying dates between apps before a visit, and it keeps every rating tied to the right cycle day.
Bipolar Journey includes the Period Tracker for start and stop dates, flow, and how heavy bleeding felt, in the same record as the sleep and mood entries. Insights then relates each cycle to the ratings from the same weeks.
What privacy steps make sense for a health log?
Mood entries, sleep hours and notes from a hard week can be read out of context by someone who was not there. Keep the log behind a passcode, avoid shared devices, and agree with your clinician or a trusted person on what you share and when.
Entries you add to Bipolar 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.
