Founder & Author, Cyluna
I'm the founder of Cyluna, and I've been living with PCOS since my teens. Cyluna exists because I spent years frustrated with period trackers that assumed a 28-day cycle: which mine never was.
Every guide on Cyluna comes from two places: lived experience with irregular, unpredictable cycles, and careful research against current guidance from recognised health authorities like the NHS, Mayo Clinic and ACOG. Where an article draws on a guideline, I link the source so you can read it yourself.
I am not a doctor. Nothing on Cyluna is medical advice: it's education and estimation tools built to help you understand your own body and have better conversations with your healthcare provider. Every article tells you when symptoms warrant seeing one.
