Real Stories from Real Women
"I spent years being told my pain was normal or psychosomatic. Using Ona helped me identify patterns that led to my endometriosis diagnosis. Having that validation changed my life."
Veronica B.
28, Project Manager
"I was prescribed the pill at 20 to manage period issues. Ten years later, when I wanted to get pregnant, I realized how much the pill had masked, not healed. Ona helped me prepare and navigate that transition—and now I'm no longer afraid of my cycles."
Sarah L.
34, Finance Director
"I only recently learned about my PCOS while also starting perimenopause—it felt overwhelming. Ona helped me make sense of it all with a daily checklist and answers tailored to me. That gave me confidence through a confusing time."
