IVF failed me twice.

Then a chance encounter led to a guy who became a known donor. The rest is history.

I birthed my daughter aged 44.5 with no complications. And yet during IVF treatment, I was twice advised to use a donor egg, and a Spanish clinic refused to treat me with my own eggs — asserting that a successful outcome was "improbable."

I was a solo woman who had never tried to get pregnant, so my fertility was unproven. I didn't accept diagnoses based on my age.

After numerous requests, I wrote up the eighteen months that led to my daughter. It is a month-by-month account of everything I did in the lead-up to conceiving — the supplements, the tests, the protocols, the holistic approaches, and the things I'd do differently.

Shared for ideas, not to copy. Each path should be built around the individual and what their specific situation calls for. This is not medical advice.
