Erratic cycles
Cycle mapping may helpPerimenopause with erratic cycles
When cycles are 24 days one month and 45 the next, you can't aim a single blood test at "day 21". The map shows what kind of cycles you're having.
Who it helpsDUTCH Cycle Mapping, Explained
DUTCH Cycle Mapping measures estrogen and progesterone metabolites across a whole menstrual cycle. Instead of one day's dried-urine collection, you collect a series of samples, and the laboratory plots the results against the days. The map shows when estrogen rose, whether and when ovulation happened, and what the progesterone phase looked like afterwards. It may explain symptoms that a day-21 blood test cannot show. For many women, it confirms what the calendar already shows.

How cycle mapping works
A series of small samples across one cycle, plotted against the days.
You collect small dried-urine samples on a series of days spread through one cycle, from a few days after your period until just before the next one, with the collection days keyed to your usual cycle length. One of those days is usually a full DUTCH Complete or Plus collection, which adds cortisol, androgens and the estrogen-metabolism pathways; the rest measure the two markers that matter for the map, an estrogen metabolite and a progesterone metabolite. The samples dry on filter paper, go back to the lab by post, and the report shows two curves.
If you're new to the test itself, start with our DUTCH test explainer.
The report shows:
- 1
The estrogen rise
in the first half of the cycle, and whether it peaked and fell as expected around ovulation
- 2
Whether ovulation happened
from the progesterone curve that follows it, and roughly when
- 3
The luteal phase
how high progesterone rose, how long it stayed up, and whether it fell early
- 4
Where your symptoms sit

Who gets real value from it
Perimenopause with erratic cycles.
When cycles are 24 days one month and 45 the next, you can't aim a single blood test at "day 21". The map shows what kind of cycles you're having: ovulatory with a short progesterone phase, long estrogen-only stretches without ovulation, or a mix. That can inform whether cyclic progesterone would help mood swings, sleep or heavy bleeding. See perimenopause vs menopause for what the hormones do in the transition.
PMS and PMDD.
Symptoms that cluster in a specific window are easier to treat when you can see what estrogen and progesterone were doing in that window.
Suspected luteal-phase problems.
Spotting before periods, short cycles, or fertility questions where the length and strength of the progesterone phase matters.
Mid-cycle symptoms
such as migraines, mood dips or palpitations that seem to track hormones but don't fit the textbook timing.
Who doesn't need it
After menopause.
There's no cycle to map; a single-day DUTCH or a blood panel answers postmenopausal questions.
On hormonal contraception or a hormonal IUD.
The map shows the contraceptive, not you.
For diagnosing perimenopause or menopause.
Age, symptoms and period pattern do that; the map explains the pattern but doesn't change the diagnosis.
For dosing hormone therapy.
Urine metabolites don't reflect transdermal estradiol well, and dosing is decided on symptoms with blood levels as a check; see how hormone tests work.
As a general check-up.
A long report that doesn't change the plan adds cost.
Cycle mapping vs a day-21 progesterone blood test
Day-21 blood progesterone
- What it answers
- Did I ovulate this cycle?
- Needs a predictable cycle
- Yes, to time the draw
- Cost
- Low
- Measures
- Serum level at one moment
- Good for
- Fertility work-up, confirming ovulation
- Guideline standing
- Standard
DUTCH Cycle Mapping
- What it answers
- What did estrogen and progesterone do across the whole cycle?
- Needs a predictable cycle
- No; that's the point
- Cost
- Higher; an add-on to a DUTCH panel
- Measures
- Urine metabolites across days
- Good for
- Irregular cycles, PMS/PMDD, symptom-timing questions
- Guideline standing
- Not in menopause-society guidelines; used in integrative practice
If your cycles are regular and the question is simply whether you're ovulating, blood is cheaper and standard. If your cycles are chaotic or your symptoms are timed, mapping may be useful.
What a report looks like, in plain words
What the two curves usually show.
A typical perimenopausal map shows an uneven estrogen line, sometimes much higher than expected in the first half, and a progesterone curve that's either absent (no ovulation that cycle), late and short, or present but low. A typical PMS map shows ovulation on time with symptoms clustering as progesterone falls in the last days. The report also flags where your values sit against the lab's reference ranges, which are the lab's own. Review the curve with your symptom diary and a clinician rather than relying on the colour-coded gauges.
What a cycle map can show.
Illustration- Estrogen
- Progesterone
PMS map. Ovulation on time, with symptoms clustering as progesterone falls in the last days.
No ovulation. An uneven estrogen line, sometimes much higher than expected in the first half, and no progesterone curve: no ovulation that cycle.
Late and short. Ovulation comes late, and the progesterone phase is short.
Present but low. Ovulation happens, but progesterone stays low.
What happens after the results
A DUTCH report leads to a treatment conversation. The options are:
Erratic estrogen with low progesterone in perimenopause
opens the question of cyclic progesterone or hormone therapy for mood, sleep and bleeding.
Low estrogen after menopause
with symptoms is the ordinary case for hormone therapy, decided on how you feel, with blood levels as the check once you're on it.
A flattened or late-peaking cortisol curve
points to the sleep and stress work on our fatigue and sleep pages, and sometimes to treating the night sweats that are driving it.
Androgen pathway findings
inform the options for hair thinning and low libido.
The test explains; care starts with a $99 video visit, with pricing published.

How Golden Leaf Health uses it
We don't sell the DUTCH kit online and we don't order cycle mapping routinely. When a clinician thinks the map would change your plan, typically for erratic perimenopausal cycles with symptoms that don't fit, it can be ordered after you see the price. We can also interpret a map you already have from another practice. Most women we see don't need it, and we'll say so. Book a first visit to talk through whether it fits your situation.
Questions, answered plainly.
What is DUTCH Cycle Mapping?
An add-on to the DUTCH dried-urine test in which you collect a series of samples across one menstrual cycle instead of a single day. The lab measures estrogen and progesterone metabolites in each and plots them, so you can see the estrogen rise, whether and when ovulation happened, and the shape of the progesterone curve afterwards.
Who should do cycle mapping?
Women who are still cycling and whose question is about the cycle itself: irregular or changing cycles in perimenopause, PMS or PMDD, suspected short or weak luteal phases, unexplained mid-cycle symptoms, or fertility questions. It isn't useful after menopause or on hormonal contraception, because there's no natural cycle to map.
Is cycle mapping better than a blood test?
It answers a different question. A single blood progesterone about a week before your period confirms whether you ovulated, cheaply. Cycle mapping shows the whole curve, which matters when cycles are irregular and you can't predict which day to draw, or when symptoms cluster at a specific point in the cycle.
How much does DUTCH cycle mapping cost?
It's priced as an add-on to a DUTCH panel, and the total varies by lab, by clinician and by what else is ordered. Golden Leaf Health doesn't sell the kit online; if a clinician recommends it, the price is in front of you before anything is ordered.
Can cycle mapping diagnose perimenopause?
It can show the erratic pattern typical of perimenopause, such as cycles without ovulation or a weak progesterone phase. Perimenopause is diagnosed from your age, symptoms and period pattern.
