Symptom · Adenomyosis tracker
The bleeding wasn't normal. Neither was the cramping.
The day-to-day companion to the full endo & adeno guide, focused on the three signals that get adenomyosis taken seriously: bleeding volume, clot size, and cramp severity. Up to 1 in 5 women have adeno, and in perimenopause the bigger estrogen swings often turn the volume up: floods, clots, cramping that doubles you over. Two months of honest tracking is the fastest route to the right scan and the right conversation. If you want the broad picture (what it is, HRT decisions, hysterectomy outcomes), start with the full guide.
Educational · not medical advice
Adenomyosis is endometriosis's close sibling, same kind of rogue endometrial-like tissue, but burrowed into the wall of the uterus itself. Every cycle that tissue tries to bleed inside the muscle, which is why the classic adeno picture is the one no one warns you about: clot-filled flooding, period pain that's actually labour-shaped, a uterus that feels heavy and crampy even between bleeds. In perimenopause it usually gets louder before it goes quiet, and it's routinely written off as 'just your age'. It isn't. It's a recognized, imageable, treatable condition. The fastest way to get the right scan and the right conversation is two months of honest, specific tracking, bleeding volume, clot size, cramp severity. The rest of this page is built around that.
Why this is happening now
Adenomyosis behaves differently from endometriosis even though they share a lot of biology. Knowing the differences sharpens the conversation with a doctor or specialist.
- 01
Endometrial-like tissue growing inside the uterine wall
In endometriosis the rogue tissue grows outside the uterus, on ovaries, bowel, bladder. In adenomyosis it's the same kind of tissue but inside the muscle of the uterus itself (the myometrium). Each cycle it responds to estrogen, builds, and tries to shed, but it's trapped inside muscle, so the result is a uterus that becomes enlarged, boggy and inflamed. That's why the cramping feels different from a normal period: it's the uterus contracting around tissue that has nowhere to go.
- 02
The three classic signals: heavy bleeding, big clots, severe cramping
Heavy menstrual bleeding (soaking pads or tampons hourly, flooding, large clots, anything bigger than a 50p coin or a US quarter) plus severe cramping plus a uterus that feels heavy and tender even between periods is the textbook adeno picture. Many women describe the cramping as 'labour-like' rather than 'period-like'. If two of three are true and they're getting worse, this deserves imaging.
- 03
Imaging can usually see it, if someone looks
Adenomyosis has fairly characteristic features on transvaginal ultrasound and MRI: a bulky uterus, thickened junctional zone, small cysts in the muscle wall, asymmetric uterine walls. A good MRI is the most accurate non-surgical diagnosis. A 'normal scan' from a non-specialist sonographer doesn't rule it out, ask specifically for an adenomyosis-aware ultrasound or MRI.
- 04
Perimenopause usually makes it worse, temporarily
Estrogen swings get bigger and more erratic in your 40s, and adeno is estrogen-fed. Many women see the bleeding get heavier, the clots get bigger, and the cramping get longer in perimenopause, sometimes leading to a long-overdue diagnosis. It often quietens after menopause when estrogen drops, but not always (fat tissue keeps making estrogen, and HRT can re-activate it).
- 05
Up to a third of people with adeno also have endometriosis
They're sister conditions and they often co-exist. If you have severe period pain, pain with sex, cyclical bowel or bladder symptoms, that's the endo overlap, and it deserves looking into too. The full sibling story is in the endometriosis & adenomyosis guide; this page is the adeno-specific tracking companion.
- 06
Hysterectomy is genuinely curative, for adeno specifically
This is the single biggest practical difference from endometriosis. Adenomyosis lives in the uterine wall, so removing the uterus removes the disease. For women who are done with the uterus, hysterectomy resolves adeno completely. For women who want to keep the uterus, uterine-sparing options exist (adenomyomectomy, uterine artery embolization), but they're specialist territory and they're not first-line.
What tends to help
Most of the day-to-day toolkit overlaps with endometriosis. The decisions that look different for adeno are flagged below.
The hormonal IUD (Mirena) is often the strongest first move
For adenomyosis specifically, the levonorgestrel IUD has the strongest evidence among hormonal options, it thins the endometrium, dramatically reduces bleeding volume, and often takes the cramping down with it. Many women who were heading toward hysterectomy buy years of better quality of life from a Mirena. It's not magic for everyone (insertion can be rough on a bulky uterus, and some women expel it), but it's worth asking about first.
Continuous combined pill or progestin-only options
Skipping the bleed (continuous combined pill, dienogest, norethindrone) takes the monthly trigger away. For adeno the goal is the same as for endo: stop the cycle that's feeding the disease, and let the uterus calm down. Each option has trade-offs, a specialist conversation, not a default doctor (family doctor) one.
Uterine-sparing surgery, if you're not done with the uterus
Adenomyomectomy (cutting out adenomyosis tissue while preserving the uterus) and uterine artery embolization (cutting off blood supply to the affected area) are real options for women who want to keep their uterus, for fertility reasons or otherwise. Both are specialist procedures with mixed long-term evidence. Worth knowing exist; not first-line.
Hysterectomy, the cure, when it's the right call
If you're done with the uterus and the disease is severe, hysterectomy is curative for adeno. Unlike with endo, you don't need a high-volume specialist excision surgeon, a competent gynecologist doing the procedure removes the disease by definition. Ovaries usually stay (they don't have adeno). The decision is about whether you want a hysterectomy, not whether it'll work.

When this needs more than self-care
7 more signs it needs a doctor this week
Soaking through a pad or tampon every hour, for hours
This is the clinical definition of heavy menstrual bleeding and warrants investigation regardless of cause. With a heavy crampy uterus and large clots, adenomyosis goes to the top of the list. Push for a transvaginal ultrasound by an adeno-aware sonographer or an MRI, not a generic pelvic scan.
Clots bigger than a 50p coin or quarter, repeatedly
Large clots, multiple per day, across multiple days, especially in your 40s, are a strong adenomyosis signal, and routinely dismissed as 'just perimenopause'. Bring your tracker. The numbers are what changes the conversation.
Period pain that stops your life
Cramping bad enough to mean missed work, vomiting, strong painkillers, or hours curled up unable to function is not normal period pain. With heavy bleeding and clots alongside it, push for an adeno- and endo-aware referral, not just 'try the pill and come back'.
Symptoms of anemia, exhaustion, breathlessness, dizziness
Heavy adeno bleeding causes iron deficiency routinely. Ask specifically for ferritin (the iron stores marker), not just a hemoglobin check, ferritin can be very low while hemoglobin is still 'normal range'. Treatment changes how you feel within weeks.
A bulky, heavy, tender uterus on examination
If a doctor or specialist examines you and notes the uterus feels enlarged or boggy, that's a classic adeno finding and warrants imaging. Equally, if you're describing that yourself and being told 'that's normal at your age' without imaging being offered, that's a flag to seek a second opinion.
Symptoms continuing or returning after menopause
Pelvic pressure, bleeding, or cramping after menopause is not 'in your head'. Post-menopausal bleeding always warrants investigation regardless. Adeno can be re-activated by HRT, and residual symptoms or scar-tissue effects are real. A menopause-aware gynecologist is the right door.
HRT being suggested without acknowledging the adeno
If you've kept your uterus, an estrogen-only regimen can re-activate adeno; the right choice is a combined (estrogen + progestogen) regimen, the hormonal IUD as the progestogen arm, or tibolone. If a doctor or specialist is suggesting estrogen-only HRT post-hysterectomy without asking about your adeno history, ask for a menopause-specialist opinion.

Practices to try this week, voices worth hearing, books worth your bedside table, rooms where members are talking, the candid tips Nila would share over a cup of tea, and the research the editorial team is watching.
Bleeding volume, pads, tampons, flooding episodes
Count pad/tampon changes per day. Note 'flooding' (clothes/sheets through), having to double up, getting up in the night to change protection, or being unable to leave the house on heavy days. 'Heavy menstrual bleeding' clinically = soaking through one pad/tampon per hour for several consecutive hours, OR a bleed that interferes with normal life. Either threshold deserves investigation. Use the tracker on /symptoms with the 'Adenomyosis flare' chip, log volume in the notes.
Clot size, and how often
Note clots bigger than a 50p coin (UK) or a US quarter / 2.5cm. These are clinically significant and a classic adeno flag. Track how many days of your bleed have large clots, and roughly how many per day. 'A few small clots once' is normal; 'fist-sized clots multiple times a day for four days' is not, and the difference is what the scan referral hinges on.
Cramp severity, and whether it's labour-shaped
Pain score 1 to 10, when it starts (days before bleeding, day of, throughout), and what it stops you doing (work, sex, exercise, sleep). For adeno specifically, note if the cramping feels deep, low, and contraction-shaped (rising-and-falling, like labour) rather than the steady ache of a normal period. That description in your tracker is the one that makes a doctor or specialist sit up.
Days of bleeding per cycle, and how short the cycles are getting
Bleeding for 8+ days, or cycles consistently shorter than 24 days, are both red flags for adeno (and more broadly for needing investigation in perimenopause). Track first day to last day of every bleed and how many days between cycle starts. Even rough numbers, kept consistently, are useful.
Heavy/crampy uterus between bleeds
A uterus that feels heavy, full, or low-cramping even when you're not bleeding is one of the most distinctive adeno experiences, and one of the least asked-about. Note days where you feel it. This is the kind of detail doctors or specialists don't think to ask for and that points squarely at adeno over a generic 'heavy periods' workup.
Energy, breathlessness, dizziness, the anemia signals
Heavy bleeding from adeno causes iron-deficiency anemia routinely, and it's often what's making you feel terrible day-to-day on top of the bleeding itself. Track exhaustion, breathlessness on stairs, dizziness on standing, brain fog. Ask for ferritin (not just hemoglobin) at your next bloods, low ferritin with normal hemoglobin still warrants treatment.
