MIRA FOR TRYING TO CONCEIVE
My period app got my fertile window wrong for 18 months. That cost me getting pregnant.
My actual LH surge was landing 8 days later than what the app predicted.
A hormone chart doesn't get you pregnant, understanding it does. Mira Ultra4™ tracks four key fertility hormones LH, E3G (estrogen metabolite), PdG (progesterone metabolite), and FSH, and turns them into clear, personalized insights. No guesswork.

Only 12.7% of women accurately know their own ovulation day1
Test strips give lines. Mira gives numbers, replacing the guess with real data from day one.
Most trackers snapshot a single moment in time. Mira looks at your whole cycle, follicle growth through confirmed ovulation², so you see the hormone patterns behind your fertile window, not just the date. Built to adapt, whether you're Trying To Conceive or navigating PCOS and irregular cycles.

How Mira ultra4 works for trying to get pregnant
See past the calendar math.
Most period apps assume ovulation on day 14 of a 28-day cycle. If yours doesn't match, your fertile window can be missed by a week.
Mira Ultra4 tracks four hormones daily, LH, E3G (estrogen metabolite), PdG (progesterone metabolite), and FSH, based on your body, not an average.
Get the numbers, not just a surge.
Ovulation strips only detect an LH surge, they don't confirm you actually ovulated.
Mira tracks LH alongside PdG (progesterone metabolite), so you can see the surge and the confirmation, in real numbers instead of a line you have to interpret.
Mira is validated against the clinical gold standard: in a blinded study against ultrasound monitoring, Mira matched ultrasound-confirmed ovulation in 96% of cycles³
Know for sure, cycle after cycle.
Every test builds your hormone history in the free Mira App — so instead of hoping this is the month, you can see your actual pattern and plan around it.

¹ In a blinded clinical study comparing Mira hormone tracking with ultrasound monitoring, Mira identified ovulation within ±1 day in 96% of cycles. Study included regularly cycling women aged 18-45. Bouchard et al., Reproductive BioMedicine Online (2026).
² Up to 99.5% detection accuracy for LH and PdG, based on internal laboratory testing under controlled conditions using known hormone concentrations. Reflects analytical performance (true positive and true negative classification), not clinical or real-world accuracy. Individual results may vary.
³ Pregnancy test: detects pregnancy up to 6 days before your missed period. Accuracy is lower when testing earlier: 78% at 5 days before and 38% at 6 days before your missed period.
⁴ Pregnancy test: over 99% accurate from the day of your expected period.
*84% of Mira users got pregnant within 6 cycles. Based on a retrospective analysis of Mira users who reported pregnancy outcomes within the Mira app. Results are observational, self-reported, and not from a randomized controlled trial. No control group was included. Individual outcomes may vary.

Why Mira
Full hormone picture
Measures LH, E3G (estrogen metabolite), PdG (progesterone metabolite), and FSH. A full hormone picture, not just one surge.
Confirms ovulation
Tracks PdG (progesterone metabolite) alongside your LH surge, so you can see whether ovulation likely followed, not just a spike and a guess.
Real numeric data
FluoMapping Technology™** delivers real numeric hormone values. The same fluorescent detection method used in lab immunoassays, not a line you have to interpret.
Predicts your unidentified
Mira Core™ decodes your results and predicts your fertile window, trained on 42M+ real hormone data points, not population averages.
Doctor-ready data
Every result becomes a doctor-ready report, so you can bring real data to your next appointment.
