How does Mira work with PMS?
01.
See what's actually driving your mood, energy, and breakouts
Mira reads a urine sample every morning — FluoMapping™ tags your hormones and measures the light they give off into an actual hormone number, not a line on a strip or a calendar guess.
That's your baseline: what's normal for you, and what's behind the mood dip, energy crash, or breakouts.
02.
Connect the symptoms that repeat to the hormone pattern behind them
PdG is the progesterone metabolite Mira tracks — the hormone that should rise steadily after ovulation to balance out estrogen and support your mood before your period.
When that rise comes in weaker, symptoms like irritability or cramping tend to hit harder. Mira tracks it daily, so you see the pattern instead of wondering.
03.
Let Mira Core™ turn your numbers into personalized next steps
Mira Core™ is the intelligence layer behind your numbers — it decodes what your hormones are doing, predicts your pattern before it repeats, and turns that into a next step for food, movement, or rest, based on your data specifically, not averages.

Questions, answered
No more guessing — here's exactly how Mira works.
What are LH, E3G, PdG, and FSH — and why do they matter?
These are the four hormones Mira tracks every day. LH triggers ovulation. E3G, an estrogen metabolite, rises before ovulation. PdG, a progesterone metabolite, confirms ovulation happened and shapes your mood and energy afterward. FSH signals your ovaries to get going each cycle. Together, they're the fullest picture of what's driving your symptoms — not just one piece of it.
Can Mira help me understand my PMS or PMDD symptoms?
Mira doesn't diagnose PMS or PMDD. But tracking your hormone pattern cycle after cycle can help you see whether there's a hormonal pattern behind when your symptoms show up — information many women bring to their doctor.
Does Mira work if my cycle is irregular or unpredictable?
Yes. Mira tracks your actual hormone levels rather than relying on calendar averages, so it can pick up on patterns even when your cycle doesn't follow a predictable schedule.
How is this different from a period tracking app?
Period apps predict based on averages and the dates you log. Mira measures your actual hormone levels every day, so you're looking at what your body is really doing — not an estimate.
How many wands will I need per cycle?
The Mira App gives you a personalized testing schedule, but most people use 10–20 wands per cycle. Longer or irregular cycles may need up to 30 for full coverage.
See The Pattern. Understand Your Body. Stop Guessing.
