Progesterone deficiency
Late-luteal collapse strips your nervous system's brake. Tears, rage, insomnia, sugar cravings — the brake fails before the bleed.

My period destroys me.
It isn't the cramps people talk about. It's the week before — the version of you who picks fights, cries at ads, can't get out of bed, hates her own skin. Then the bleed arrives and takes the rest.
You've been told it's normal. It isn't. Cyclical mood, rage, exhaustion and pain at this intensity have measurable drivers — progesterone, oestrogen clearance, magnesium, thyroid, blood sugar — and we test for all of them.
The Picture
If this is you,
it might sound like —
Read these the way you'd read a letter from someone who already knows. If three or more land hard, you're in the right place.
- I lose a week of every month.
- I cry for no reason — and it's always 7 days before my period.
- I rage. I'm not normally like this.
- PMS used to be mild. Now it takes me out.
- I bleed heavily — clots, flooding, exhaustion.
- Cramps that send me to bed.
- My breasts feel like they belong to someone else for two weeks.
- I wonder if it's PMDD, depression, or perimenopause.
+ Key Drivers
What we're actually looking at.
"PMS" and "heavy periods" are the headline. Underneath sit six measurable systems that, once tested, explain almost everything you feel in the second half of your cycle.
Oestrogen excess
Often not too much oestrogen, but oestrogen the body can't clear. Heavy bleeds, breast pain, mood swings, fluid retention.
Magnesium, B6 and zinc depletion
The cofactors your hormones need to behave. Without them, "PMS rage" is the default setting, not the exception.
Subclinical thyroid dysfunction
Quietly worsens every PMS symptom. A "normal" TSH alone misses up to half of the women who are actually under-converting T4 to T3.
Blood-sugar instability
Late-luteal crashes look identical to rage, anxiety and crying jags. The fix is rarely about the period — it's about breakfast.
Liver and gut clearance
If you can't excrete oestrogen via the bowel, you reabsorb it. Constipation is a hormone problem more often than a fibre problem.
+ Key Tests
How we see the cycle.
Not a single oestrogen reading on day 21. The full picture — across all four weeks — so the protocol fits your biology, not the average woman's.
-
ENDOmap · DUTCH cycle mapWhat your hormones actually do across all four weeks. Oestrogen and its clearance pathways, progesterone, testosterone, DHEA, full cortisol curve and melatonin — collected in dried urine at home.
-
HTMA · Mineral panelMagnesium, copper:zinc ratio, calcium, sodium and the trace minerals your hormones depend on. Hair tissue analysis shows what the bloodstream hides.
-
OAT · Organic acidsB-vitamin status, neurotransmitter metabolites, mitochondrial function, gut dysbiosis markers — the upstream chemistry behind mood and oestrogen clearance.
-
GP bloods · Full panelFree T3, free T4, reverse T3, thyroid antibodies, complete iron studies, vitamin D, fasting insulin, HbA1c and inflammation markers. Far beyond the standard "tired and bloods normal" workup.
+ Foundational Must-Haves
What you can start today.
These aren't a treatment — they're the floor your body needs before any protocol can work. Most women feel a meaningful shift inside one cycle.
- 300–400 mg magnesium glycinate taken in the second half of your cycle. The single biggest lever for PMS rage and sleep loss.
- Protein at breakfast every day — 30 g minimum. Stabilises blood sugar before the late-luteal crash that drives rage and tears.
- Hard cap on alcohol in the luteal phase. Strips B6 and stalls oestrogen clearance — the worst combination at the worst time of the month.
- A daily bowel movement. Non-negotiable for hormone clearance. Constipation re-circulates the oestrogen you just spent two weeks producing.
- 20 minutes of morning daylight. Anchors your circadian rhythm and the cortisol curve that progesterone is built on top of.
- Track your cycle by symptom, day-by-day. The pattern is the diagnosis. Apps like Read Your Body or a notes file work fine — just be consistent.
+ The Process with How It Heals
We test before we treat.
You shouldn't be on an SSRI for a magnesium deficiency. You shouldn't be told to "just live with" losing a week of every month. The 22-week reset uses your six functional tests to build a protocol designed for your biology — across hormones, minerals, thyroid, gut and blood sugar — and adjusts as we go.
Most clients see a measurable shift by cycle two. By cycle five, the question stops being "how do I cope this month?" and starts being "what do I actually want to do with my life?"
+ From the women in front of us
What changed.
Selected from clients who started here — with cyclical mood collapse and heavy bleeds — and worked through the 22-week reset.
I haven't cried for no reason in three months. I'd forgotten what calm felt like — I thought that part of me was gone.

First cycle in years where I didn't lose a week. The DUTCH test showed exactly what was wrong, and the protocol matched it.
