Irregular cycles
A record that still works when your cycle has no pattern
Log the days you bleed and the days you do not. When a period comes after 45 days, or not at all for three months, the gap is in your diary as a fact, not a late alert.
PCOS tracker app for irregular cycles and symptoms
A symptom diary for PCOS that does not depend on a regular cycle. Log bleeding, pain, bloating, food and stress, then take a PDF report to your doctor.
Why a diary helps when your cycle is irregular
PCOS is a hormone condition that can affect periods, hair growth, fertility and mood, and the NHS now calls it PMOS. Periods can be unpredictable, absent, or heavy, long and painful, and some people have skipped periods or no periods at all.
Period apps guess your next period from your last few cycles. When the gaps change from month to month, those guesses are often wrong. A diary does not guess. It keeps the dates you bled, the days you had pain and what else was going on, so your doctor sees what happened instead of a prediction. Read more in our guide to tracking irregular periods with PCOS.
- Log bleeding days and cycle notes, even when months pass between periods
- Rate your pain on a number scale and mark where it hurts on a body map
- Bring a PDF report to your GP, gynecologist or endocrinologist
What a PCOS symptom tracker should do
Keep a true record of each day, whatever your cycle does.
Beyond the period
Room for the symptoms that come between periods
Pelvic pain, bloating, tiredness and the days you feel off all go in the same diary as your bleeding, so you can see what happens on which days.
Appointments
Something to show, not only something to describe
A short appointment goes fast. A PDF report of your bleeding, pain and symptoms gives your doctor dates and numbers to look at.
What you can log in Endolog
Six parts of one diary, all on the same calendar.
Bleeding days and cycle notes
Mark each day you bleed and add a cycle note when something is different. Long gaps and spotting days show up on the calendar as they happened.
Pain and where it hurts
Score your pain on a number scale and use the pelvic body map to show where it hurts. Pain on one side one month and the other side the next is a pattern worth showing.
Bloating and other symptoms
Log bloating, tiredness and other symptoms on the days they happen, next to your bleeding and pain.
Food and how you felt after
Write down what you ate and how you felt after. Over a few weeks, you can look back and see what came before a bad day.
Stress
Log stressful days in the same diary, so they sit next to your symptoms instead of in a separate note.
A PDF report for your doctor
Export your entries as a PDF report. Print it or send it before a GP, gynecologist or endocrinologist appointment.
A period predictor or a symptom diary?
With PCOS, the date of your next period is often the hardest thing to know. Endolog records what happened instead.
| Comparison point | Generic period tracker | Endolog |
|---|---|---|
| What it is built for | Guess the date of your next period | Keep a dated record of what your body did |
| When cycles are irregular | Predictions move or go wrong, and late alerts pile up | Nothing to predict: you log what happened on each day |
| Pain | One cramps toggle | A pain score and where it hurts on a body map |
| Food and stress | Usually not part of the log | A food diary with how you felt after, plus stress logging |
| At the appointment | Screenshots, or recalling from memory | A PDF report your doctor can read in a few minutes |

PCOS tracker questions
Answers about using Endolog with PCOS.
Can I track irregular periods with Endolog?
Yes. Endolog does not need a regular cycle. You log the days you bleed, and the calendar shows the real gaps between periods, however long they are.
Does Endolog predict ovulation or fertile days?
No. Endolog is a symptom diary, not an ovulation or fertility predictor. It records what you log so you and your doctor can look at it together.
What can I log for PCOS in Endolog?
You can log bleeding and cycle notes, pain on a number scale, where it hurts on a pelvic body map, bloating and other symptoms, what you ate and how you felt after, and stress.
Can I use Endolog before I have a PCOS diagnosis?
Yes. A diary of your bleeding and symptoms is useful before a diagnosis too, because it gives your doctor dates and details to start from.
Which doctor can I show the PDF report to?
Any doctor you see about your symptoms, such as a GP, a gynecologist or an endocrinologist. The report is a summary of your own entries.
Is Endolog free?
Endolog is a free download from the Apple App Store for iPhone and iPad, with an optional in-app subscription.
Stop the medical gaslighting
Track pelvic pain, bleeding, digestive symptoms, fatigue, and flare patterns in one place. Endolog turns those daily logs into clean PDF reports you can bring to your next appointment.
