Cycle & Hormone Tracker

Move with your cycle, not against it.

Identify your current cycle phase, your fertile window, and the herbs, foods, and rituals that support each hormonal stage. Based on ACOG and Endotext clinical references.

What this does

A typical menstrual cycle moves through four hormonal phases. Each has distinct energy, mood, fertility, and nutritional patterns. Working with these waves — instead of fighting them — measurably improves PMS, energy, mood, and reproductive health.

Menstrual Phase

Follicular Phase

Ovulatory Phase

Luteal Phase

Cycle phase math follows standard reproductive endocrinology (Reed BG, Carr BR. Endotext, 2018; ACOG guidance). This calculator is for educational planning and self-awareness — it is not a contraceptive method and not a fertility diagnosis. Irregular bleeding, severe pain, or any sudden cycle change warrants a clinician visit.
