You've tracked ovulation, taken the supplements, changed your diet and timed everything perfectly. Maybe you've even been told everything looks "normal."
So why hasn't it happened?
We don't believe you're out of options. We believe there may still be important pieces of your fertility story waiting to be understood.
After years of trying and being told everything looked normal, our founder (a PhD scientist) refused to believe "unexplained." She discovered the piece everyone had missed: something standard testing simply never checked. She built the test she wishes she'd had, so you don't lose years finding your missing piece.

FOUNDER

Amy Beckley, PhD - founder & CEO · Dr. Aimee Eyvazzadeh - reproductive endocrinologist.
Amy Beckley, PhD is the scientist who built Proov after seven miscarriages and years of being told she was "fine." She created the at-home testing that finds what standard labs miss.
Dr. Aimee Eyvazzadeh is the reproductive endocrinologist who reads your results and writes your protocol. She brings the clinic-level care that usually takes months to access.
Amy finds the missing piece. Dr. Aimee decides what to do about it. Together that's the F.A.S.T. Method.
F.A.S.T. finds what standard testing often misses. Most 'unexplained' infertility comes down to four measurable things: timing, ovulation, progesterone, and egg quality. We track all four at home with real hormone data and doctor-guided prescriptions from Dr. Aimee Eyvazzadeh.

Complete a medical intake. Dr. Aimee reviews within 48 hours and prescribes letrozole, progesterone and metformin (if indicated). Medications and test kits ship to your door before your next cycle.

Take letrozole nightly for 5 nights - the same oral medication used in fertility clinics - to support stronger, healthier ovulation.

First-morning-urine tests for FSH, E1G/estrogen, LH and PdG. The Proov app tells you which test to use, when, and reads every result for you.
The app opens your full fertile window - up to 6 days, not the 2 an OPK shows - so you can time intercourse across all of it.

PdG confirms ovulation actually happened (not predicted), and you start progesterone that night to support the implantation window.
If that stopped you - good. You should question anyone who wants to put you on a fertility medication. So here's the honest answer to why this isn't backwards.
You've already spent money and months on guessing. Here's what the next steps typically cost when you go looking for answers the traditional way.
F.A.S.T. isn't a replacement for a clinic or for IVF. It's the step most women are never offered before them: three cycles of at-home hormone monitoring, a doctor's review and prescriptions where indicated, so that if you do go further, you go with answers instead of guesses.

Answers first. Big bills only if you truly need them.
Everything you need to test from home.
Typical U.S. out-of-pocket ranges, 2026. Costs vary by clinic and insurance.
Women who were told everything looked normal. Women who kept going anyway. When you start F.A.S.T., you join a community that talks openly about cycles, data, grief and hope - and celebrates every piece of progress.
Everything looked 'normal'
"Every lab came back fine, but something was clearly missing. F.A.S.T. showed my PdG dropping too soon - the one thing nobody had checked. Two cycles later I was pregnant."
The gap nobody found
"A year of being told to 'just keep trying.' F.A.S.T. found the gap in six weeks. It wasn't unexplained, it was unmeasured."
Finally, an actual answer
"I'd almost given up on getting a real explanation. F.A.S.T. caught what every other test missed and gave us something we could actually treat."

The only question is whether you'll have data from it. F.A.S.T. starts before your next cycle begins - four hormones tracked at home, read by the doctor who writes your protocol.
And if all four come back clear? That's not another shrug. It's four things ruled out with real data, and a place to start the next conversation.
