PROGESTERONE: MORE THAN A CYCLE TRACKER

Understanding progesterone, the ovulation signal.

Regular tracking shows whether and when you ovulate, so you can spot hormonal issues early.

Progesterone is central to everyday health.

Progesterone rises after ovulation and quietly supports vital systems throughout your cycle, regulating:

  • Sleep quality
  • Emotional resilience
  • Body temperature
  • Menstrual regularity
  • Cognitive clarity
  • Bone and metabolic health

This hormone doesn’t just confirm ovulation—it sets the tone for what follows.

What impacts progesterone levels?

Short luteal phases, anovulatory cycles, and stress-related disruptions can prevent a healthy progesterone rise. If your levels stay low in the luteal phase, you might notice:

  • Irregular periods
  • Trouble sleeping
  • Mood swings or anxiety
  • Premenstrual symptoms
  • Temperature shifts

Progesterone and your menstrual health.

In-range peak

Low peak

No peak

Clear progesterone rise confirms ovulation.

Ovulation happened, but stress, age, or luteal issues led to a weak progesterone response.

No post-ovulation rise—often due to anovulatory cycles triggered by stress or hormonal imbalances.
