Hormone Truths Every Woman Needs to Know
As a Woman
How cycles change with diminished reserve
Natalie explains cycle shortening, luteal changes, and chaotic estrogen as ovarian reserve declines.
Dr. Natalie Crawford, board-certified OB-GYN and REI, breaks down how your hormones shift across your 20s, 30s, 40s, and beyond, and what you can actually do in each decade to protect your fertility, brain, bones, and long‑term health. Instead of reacting only when there’s a problem, this episode helps you use your cycle, symptoms, and lifestyle as data so you can make informed decisions at every stage.
