Not a cycle tracker. Not an app that tells you to drink more water.
It is the brief you bring with you so the doctor cannot dismiss you.
You have heard all of these. We built the answer to each one.
The average woman waits more than four years to be diagnosed with PCOS, and often leaves the appointment with a prescription instead of a plan. PCOS Nav exists to change what you walk out with.
"You should lose some weight and come back."
"Your labs are normal."
"Just take the pill and see how you feel."
"There's nothing else we can do."
Four tools. One goal. Never walk in unprepared again.
Lab decoder
Enter your bloodwork. Every value is compared against PCOS-optimal ranges, and the gaps your doctor did not flag are surfaced in plain language.
Appointment scripts
The exact questions to ask, labs to request, and language to use so you stop leaving the clinic with the same vague advice.
Evidence library
Every recommendation links to the peer-reviewed study behind it. Bring the citation, not just the request.
From "your labs are normal" to a real plan, in one sitting.

"PCOS" is not one thing. Your plan should not be either.
Phenotype A
Insulin-Resistant PCOS
The most common pattern. Driven by insulin dysfunction affecting androgen production. Responds strongly to metabolic interventions.
Phenotype B
Post-Pill PCOS
Triggered by coming off hormonal birth control. Often temporary. Responds to cycle-supporting nutrients and time.
Phenotype C
Inflammatory PCOS
Driven by chronic low-grade inflammation that stimulates androgen production. Responds to anti-inflammatory lifestyle shifts.
Phenotype D
Adrenal PCOS
Elevated DHEA-S from adrenal androgen excess, not ovarian. The rarest type, and often mismanaged when treated like insulin-resistant PCOS.
I walked in with the script. I left with the labs I had been asking for for three years.
