- PMDD is recognized by symptom timing, so each entry needs a cycle day (AAFP).
- Women with type 1 diabetes were studied for glucose changes by cycle phase; the figures and their limits are in the sections below.
- Readings, meals, medicines and mood words become useful to a clinician when each carries a date and a cycle day.
- PMDD Journey keeps cycle dates, daily check-ins, meal lines, medicine entries and free-text notes in one dated history, and exports a one-page Doctor Report.
Living with PMDD and diabetes means two sets of records that rarely meet. A meter or sensor holds numbers. A notebook or app holds mood, irritability and anxiety. Neither shows the cycle day unless you add it.
This guide covers seven things to write down: cycle dates, late-luteal readings, look-alike symptoms, appetite and meal lines, a medicine list, distress and mood words, and the pages to bring to a visit.
Cycle days plus period start dates for PMDD and diabetes records
PMDD is identified by timing, and the AAFP guideline summary calls the timing of symptoms the most important element of diagnosis. Diabetes adds a second set of dated numbers. The two sets line up only when both use the same calendar.
A pilot study followed 12 women with type 1 diabetes for 3 cycles and confirmed ovulation in 33 of 36 cycles. Glycemic variability changes were specific to each individual and linked to the phase of the cycle. A group result gives a direction, and your own dated lines show your own pattern.
Write these anchors for every day:
- The first and last day of bleeding.
- The cycle day number, counted from the first day of bleeding.
- Mood, irritability, anxiety and energy in a few plain words.
- Any reading your diabetes team asked you to take, copied as a short note.
From PMDD Journey (by Health Journey Labs), we recommend entering the period start date first in every cycle, because each later day takes its number from it. Setup steps are in the first-steps guide to tracking PMDD.
The Period Tracker records start and stop dates and how heavy or light the bleeding felt, which gives every day its cycle number. The Daily check-in adds mood, irritability, anxiety, sleep and energy for that same date. In the calendar view of PMDD Journey, days are colored by intensity, so the hardest days can be read against the dates of your reading notes.
Late-luteal glucose readings and PMDD mood days: the figures and how to log them
The T1DEXI analysis included 179 women with type 1 diabetes. It compared the 2 to 4 days after menstruation began with the 2 to 4 days before the next one. Mean glucose rose from 148 to 155 mg/dL, and mean time in range fell from 73% to 70%. The difference was not explained by the exercise, insulin or carbohydrate data the study collected.
These are group means. Cycle-linked changes in the studies were individual, so a clinician reads them alongside your own records. The cited studies enrolled women with type 1 diabetes, and a clinician can say which readings matter for another type of diabetes.
For each reading you already take, add:
Late-luteal glucose readings and mood days
PMDD Journey records the cycle day with each reading.
- The cycle day and the date.
- The source in words, such as meter or sensor.
- Meal or snack lines noted before the reading.
- Mood and irritability words for the same day.
Write the reading as typed or spoken text. Keep the units your device shows.
A line in the Daily Journal, typed or dictated by voice, holds the reading exactly as written, with the cycle-day context in the same entry. The Flare Tracker flags a day clearly worse than a usual week, so a very hard mood day and a higher reading can be compared on one date. PMDD Journey insights strengthen as more cycles are added.
Anxiety, racing heart, and low readings with PMDD and diabetes: logging look-alike episodes
Anxiety, racing heart and low glucose
PMDD Journey reviewed the CDC page on anxiety and low blood sugar.
The CDC diabetes mental health page states that anxiety can feel like low blood sugar and vice versa. The same page lists sweating and a racing heart as physical reactions to stress. Late-luteal anxiety in PMDD can produce the same body signals, so an episode needs its context written down.
ACOG lists depression and anxiety disorders as the most common conditions that overlap with PMS, and about half of women seeking treatment for PMS have one of them. A dated sequence helps a clinician decide which pattern needs attention.
Write each episode as five short lines:
- the first feeling
- the cycle day
- the reading, if one was taken
- what was eaten or drunk beforehand
- how the episode ended
When episodes come faster or cause worry, contact a clinician. If you are in danger, use your local emergency number. For the typical length of cycle-linked symptoms, see how long PMDD symptoms last before the period.
A sudden jittery spell goes into the Daily check-in under physical symptoms and anxiety, with the cycle day attached. The Daily Journal keeps the order of events and the reading as free text. When similar episodes fall on the same cycle days, the weekly and monthly views of PMDD Journey color those days by intensity.
Luteal appetite and thirst changes with PMDD and diabetes: meal, caffeine, and alcohol lines
ACOG lists thirst and appetite changes, including food cravings, among the physical symptoms of PMS. In the T1DEXI group, reported carbohydrate intake averaged 127 g per day early in the cycle and 133 g late in the cycle. The authors described that rise as slight.
With both conditions, a meal line has two jobs. It shows a PMDD appetite change, and it gives context to a reading taken afterward. Write the food or drink in plain words and add the cycle day.
Luteal appetite table, by PMDD Journey
| Item | What to write |
|---|---|
| Meals and snacks | Foods named in plain words. |
| Caffeine | Drink type and count for the day. |
| Alcohol | Drink type and count, or none. |
| Cravings | The food named and the cycle day. |
| Thirst | More than usual, with the cycle day. |
Order matters. A craving that comes before a higher reading and a craving that follows one raise different questions, so write which came first. Skipped or delayed meals count as facts too. Add the reason in a few words, such as a long errand or a work block, because the reason helps a clinician read the day. Caffeine and alcohol lines show what else was part of the same day.
Meal or drink lines in the Food Tracker, with caffeine and alcohol entered, let a clinician see what was eaten around higher readings and rougher mood days. The nutrition line of the Daily check-in carries the same date and cycle day. Over several cycles, PMDD Journey shows whether the appetite entries cluster in the late-luteal days.
Medicines for diabetes and PMDD: one dated record for every clinician
Two prescribers often hold two partial lists. One page that shows every medicine and supplement lets each clinician see what the other has recorded. Write names as printed on the label, and leave decisions about them to the prescriber.
Medicines for both conditions, by date
PMDD Journey keeps diabetes and PMDD medicines in one dated list.
| Column | What to write |
|---|---|
| Name | Medicine or supplement, as printed. |
| First listed | The calendar date you first recorded it. |
| Prescriber | Which clinician it comes from. |
| Clinician updates | The date and who made the update. |
| Cycle day | The day number on the date of each entry. |
Bring the labels or the pharmacy printout when you build the list, because brand and generic names can differ between clinics. Write both names when you know them. Add a few words on what each item was listed for, such as diabetes or PMDD, so each prescriber sees which lines belong to them.
From PMDD Journey, we recommend adding laboratory result dates to the same page, such as blood counts, thyroid and iron tests that a clinician ordered to rule out other causes. A visit question takes this form: Is it worth reviewing the medicine list together? Medicine entries are facts to read, and the clinician decides what they mean.
My Meds keeps medicine and supplement names, timing and medication entries, so the diabetes team and the PMDD clinician read one list. Seen with mood, sleep and cycle weeks in PMDD Journey, a listed medicine can be compared with a hard week. My Labs holds the result dates of tests a clinician ordered, read with symptoms by cycle day.
Diabetes distress and PMDD mood days: two kinds of lines for the clinician
The CDC describes diabetes distress as feeling discouraged, worried, frustrated or tired of daily diabetes care. In any 18-month period, 33% to 50% of people with diabetes have diabetes distress. The page adds that these feelings can lead to skipped blood sugar checks or missed appointments.
The same CDC page reports that people with diabetes are 2 to 3 times more likely to have depression than people without diabetes, and that only 25% to 50% of them are diagnosed and treated. Mood that stays low across the whole month is a fact worth dating, whatever the cause.
PMDD mood symptoms follow the cycle. ACOG notes that women with depression often have symptoms present all month long. Dated lines show whether low mood clusters before a period or spreads across the month.
Use two kinds of lines:
Diabetes distress and mood days
PMDD Journey writes mood words with the cycle day.
- ☐ Mood words with the cycle day, such as tearful, irritable or flat.
- ☐ Diabetes care facts with the date, such as a skipped check or a missed visit.
Keep the second kind as plain facts without judgment. Contact a clinician if mood changes quickly or worries you, and use your local emergency number if there is danger.
The Daily Journal records what the day limited and the cycle-day context, which is where the diabetes care facts belong. The Daily check-in scores mood, irritability and anxiety on the same date. My Assessments adds structured check-ins beyond daily scores, so PMDD Journey holds both kinds of mood lines in one dated history.
Two cycles of paired PMDD and diabetes notes: the one-page summary for each visit
The AAFP review advises that patients record symptoms for at least 2 cycles because symptoms can vary from cycle to cycle. For PMDD with diabetes, the same 2 cycles carry the readings, meals and medicine dates.
ACOG advises that you write down and rate symptoms each day for at least 2 to 3 months and record the dates of your periods as well. If a visit comes before that, bring what exists, with its dates.
Order the page so the clinician can read it top to bottom: period start dates first, hardest days second, reading notes third, medicines and laboratory dates last. Mark up to 3 days per cycle that stood out, and add one plain sentence about each.
Bring these pages to each visit:
Summarizing two cycles of notes
PMDD Journey starts with the period start dates.
- ☐ Period start dates for both cycles.
- ☐ Days of highest mood or anxiety intensity, with cycle days.
- ☐ Reading notes from the same days.
- ☐ The dated medicine and supplement list.
- ☐ Laboratory result dates, if any.
Three questions fit most visits. Is it worth reviewing the days of higher readings against the cycle days together? Is it worth reviewing the medicine list together? Is it worth reviewing the mood lines together? Short visits are covered in the guide to short PMDD visits (PMDD Journey checklist).
Doctor Report exports a one-page summary of cycle dates, mood and irritability, anxiety, sleep, energy, work or relationship impact and how you functioned. My Care Team holds clinician names and short visit notes, with prompts for what to ask and bring. In PMDD Journey, two cycles of paired entries reach each clinician as one page.
How PMDD Journey can help
A paper notebook can hold these lines. When readings come from a device and mood notes from a notebook, joining them before a visit means copying by hand. Best PMDD Apps 2026 reviews trackers that keep cycle dates, symptoms and medicines together.
PMDD Journey is a personal PMDD tracker from Health Journey Labs on the App Store and Google Play. For PMDD with diabetes, it lets you log cycle days, mood, meals, medicines and free-text reading notes against the same dates. After two cycles, both clinicians can read the same dated facts. Below is what you can use and how each part helps.
- Daily check-in — Scores physical symptoms, emotional state, nutrition, sleep, exercise, medicines and outside factors each day, including mood, irritability, anxiety, energy and cycle day.
- Daily Journal — Free-text or voice notes on what the day limited, cycle-day context, work strain, partner talks and visit debriefs, written in your own words.
- Flare Tracker — Flags a day clearly worse than a usual week, such as sharp irritability, a tearful afternoon or standout anxiety, and shows whether it repeats.
- My Meds — Lists medicine and supplement names, timing and entries for items you already use as directed, with first-listed dates and clinician updates.
- My Labs — Stores result dates for tests a clinician ordered to rule out other causes, such as blood counts, thyroid and iron, read with mood and symptoms by cycle day.
- Weekly Goals — Holds one small aim for the week and whether it held, read against the real check-ins.
- Learn — Short education topics and prompts on luteal-phase symptoms, cycle timing, sleep, tracking across two cycles and visit preparation.
- AI companions — Clara answers general questions, and specialist companions cover knowledge, fitness, nutrition and relationships; all of them see your logged history and can help with visit wording or a partner script.
- My Care Team — Keeps clinician names and short visit notes, with prompts for what to ask and bring, space for notes during the visit and a review afterward.
- Doctor Report — Exports a one-page summary of the logged history: cycle dates, mood and irritability, anxiety, sleep, energy, work or relationship impact and how you functioned.
- My Assessments — Adds structured check-ins beyond daily scores and collects life and social context at onboarding, read with the ongoing history.
- Food Tracker — Records meal or drink lines, including caffeine and alcohol, and reads them with mood, energy, sleep and cycle day.
- Period Tracker — Records start and stop dates, flow and how heavy or light the bleeding felt, read with mood, irritability, sleep and energy.
- Weight Tracker — Records scale numbers or body notes and reads them with energy, sleep and cycle.
A shared record gives the PMDD clinician and the diabetes team one history to read, and insights strengthen with each added cycle. Custom symptoms let you add labels such as shaky afternoon or thirst day.

FAQ
The answers below draw on the sources cited in this guide, and the app they mention is PMDD Journey (by Health Journey Labs).
Can PMDD and diabetes symptoms land on the same days?
They can. Late-luteal days carry PMDD mood and anxiety symptoms, and studies in women with type 1 diabetes report higher mean glucose in the same late-luteal window, so one hard day may involve both conditions at once.
A shared calendar in PMDD Journey lets you mark the day once and attach mood words, meal lines and reading notes to it, which shows a clinician how often the two conditions fall on the same days.
Which cycle days should I write readings on?
Write them on every day you take one, with the date and the cycle day. Studies compared early follicular days with late luteal days, so those stretches deserve the most careful notes when you must choose where to be thorough.
Entries in the Daily Journal of PMDD Journey keep the reading as free text in the same note as the cycle-day context, so no extra spreadsheet or copying is needed before you reach the visit.
How do I tell anxiety from a low reading in my notes?
The CDC page says the two can feel alike, so the notes should hold the order of events: the first feeling, the cycle day, the reading if one was taken, and what was eaten beforehand. A clinician interprets that sequence.
With the Flare Tracker in PMDD Journey, a clearly worse day is flagged, and repeated episodes on similar cycle days can be reviewed together with the Daily check-in scores for anxiety and the reading notes.
Do I need one app for both conditions?
One place is optional. A notebook, a diabetes app and a cycle calendar can all work, but the dates must match, because a clinician reads two separate sources faster when the cycle day appears in each of them.
Using PMDD Journey, cycle dates, daily check-ins, meal lines and medicine entries share one dated history, and reading notes can be written in the Daily Journal on the same day for the visit.
How many cycles should I log before the visit?
The AAFP review advises recording symptoms for at least 2 cycles because symptoms can vary from cycle to cycle. A visit sooner than that can still use whatever you have, as long as each entry carries its date.
Because PMDD Journey keeps each entry in a calendar view with days colored by intensity, you can scan one cycle and then the following cycle to see which days repeat before you book the visit.
What if my cycle length changes from month to month?
Write the actual start date of each period and count cycle days from it, gaps included. Changing lengths are facts for the clinician, and a missing entry is better left as a visible gap than guessed afterward.
The Period Tracker in PMDD Journey records start and stop dates and flow, so every cycle gets its own day count, even when its length differs from the cycle before it or after it.
Should the PMDD clinician see my diabetes medicines?
A complete list helps every prescriber see the full picture. Write names as printed on the label, the date each was first listed and who prescribed it, then ask the clinician: Is it worth reviewing the list together?
My Meds in PMDD Journey keeps medicine names, timing and entries with the mood and sleep history, which gives both clinicians one dated list to read instead of two partial lists from separate offices.
What do I write when appetite and thirst change before my period?
ACOG lists thirst and appetite changes among the physical symptoms of PMS. Write the food or drink in plain words, the amount in plain terms, the cycle day, and whether the change was stronger than your usual days.
Lines in the Food Tracker of PMDD Journey hold meals, caffeine and alcohol, and reading those lines with the cycle day shows whether the appetite entries gather in the late-luteal days of each cycle.
Can I dictate notes on a day when typing feels like too much?
Yes, if your tracker supports voice entry. A short spoken line with the cycle day and the main problem is more useful than an empty day, and further details can be added later once energy returns.
Voice entry in the Daily Journal of PMDD Journey records a spoken line as a note on that day, so a hard late-luteal day still adds to the record that you bring to the clinician.
What belongs on a visit page for both conditions?
Include period start dates, the hardest mood days with their cycle days, reading notes from the same dates, the dated medicine list and any laboratory result dates. Add three short questions in the form: Is it worth reviewing this together?
The Doctor Report in PMDD Journey exports a one-page summary of cycle dates, mood, anxiety, sleep, energy and function from the logged history, so the page is ready for the visit without any retyping.
How do I log a day when both conditions feel bad?
Write one entry that names both: the mood and anxiety words, the reading if one was taken, the cycle day and what the day limited. Splitting the day into two entries makes the link harder to see.
A Daily Journal entry in PMDD Journey records what the day limited, and a flag in the Flare Tracker marks the day as clearly worse than a usual week, which makes it easy to find for later review.
Is it common to feel worn down by diabetes care and PMDD together?
The CDC describes diabetes distress as common, often appearing after years of good management. Mood that stays low across the whole month is worth mentioning to a clinician, together with the dated lines that show how long it lasted.
My Assessments in PMDD Journey add structured check-ins beyond daily scores, which gives a clinician a fuller view of mood and function across the cycle than a single rating for each day would give.
Can an AI chat explain my pattern?
A chat tool can answer general questions and help word a visit note, but it cannot examine you or interpret your readings the way a clinician does. Use it for wording and questions, and leave decisions about care to the clinicians.
The AI companions in PMDD Journey see your logged history, including cycle dates, mood entries and free-text notes, so a request for visit wording starts from your own dated facts and not from a blank page.
What if symptoms change quickly between visits?
Contact a clinician when symptoms shift fast or cause worry, and do not wait for the next scheduled visit. If anyone is in danger, use your local emergency number. The log supports those conversations and never replaces them.
Entries in PMDD Journey show the date a change began and which cycle day it fell on, and the Flare Tracker flags the worse days, which gives the clinician a clear starting point for the conversation.
How can I protect my privacy in what I write about my health?
Entries from the late-luteal days can include anger, low mood or thoughts you would not say out loud. Protect the log with a passcode, keep it off shared devices, and agree with your clinician on how much detail to bring.
Read the privacy policy of PMDD Journey to learn how your health notes are stored and handled, and bring questions about your own care to a clinician, because medical advice for your situation comes from them.
