Periods
Heavy days, written down on the day
By the next appointment, a heavy period from two months ago is hard to describe. A note on the day says how heavy it was and what it stopped you from doing.

Log your bleeding days, how bad the pain is and where it hurts, with bloating, fatigue and stress. After a few cycles, your diary shows your doctor what each month is really like.
In adenomyosis, the lining of the womb grows into the muscle in the wall of the womb. It can cause heavy, painful periods, and pain, bloating or pain during sex at other points in the cycle. Adenomyosis often occurs with endometriosis, so many people live with both. Endolog is also an endometriosis tracker, and one diary covers the two.
The symptoms overlap with other conditions, so a diagnosis can take a long time. A doctor usually asks about your periods and pain first, and can then send you for a transvaginal ultrasound or an MRI scan. A record of your periods, pain days and symptoms over several cycles gives your GP or gynaecologist facts to work from, and helps you explain why you are asking about a scan.

Heavy and painful periods are easy to play down from memory. Notes made on the day are not.
Periods
By the next appointment, a heavy period from two months ago is hard to describe. A note on the day says how heavy it was and what it stopped you from doing.
Pain
Adenomyosis pain is not only on period days for everyone. Logging every day shows which cycle day the pain starts and how long it stays.
Over several cycles
One painful period can look like bad luck. Three or four cycles side by side show your doctor what keeps coming back.
Your period, your pain and the rest of your symptoms in one diary.
Mark the days you bleed and write a note when a day is heavy, when you pass clots, or when you had to change plans because of it.
Score the pain each day, so a bad day and a very bad day look different in your record.
Tap the pelvic body map to show where the pain is, such as low in your tummy or on one side.
Add symptoms such as bloating, pain during sex or fatigue on the day they happen.
Log stressful days in the same diary, next to your pain and your period.
If bloating is part of your week, the food diary keeps your meals next to how you felt after them.
A period app is built to predict your next period. With adenomyosis, you also need a record of the pain and the heavy days.

Answers about using Endolog as an adenomyosis tracker.
Yes. You mark each bleeding day and add notes, for example that a day was very heavy or that you had clots. Endolog does not measure blood loss, so your notes are what show how heavy a period was.
No. Endolog does not diagnose. It keeps a record of what you log, so you and your doctor can look at your periods, pain and symptoms together.
Yes. You keep one diary for both. Your pain, bleeding and symptoms are on the same calendar, whichever condition they come from.
Yes. You can log pain and symptoms on any day, not only during your period. Your record then shows when in your cycle the pain happens.
It is a summary of your own entries: your bleeding days, pain scores, where it hurts, and the symptoms and notes you added. You can print it or send it before your appointment.
Endolog is a free download from the Apple App Store for iPhone and iPad, with an optional in-app subscription.

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.
