Progesterone is produced after ovulation. As ovulation becomes less consistent in perimenopause, progesterone levels can fluctuate or decline earlier than oestrogen.

Because progesterone has calming, stabilising effects within the nervous system, changes may be noticed beyond the menstrual cycle.

Possible symptoms associated with progesterone fluctuation may include:
• Increased anxiety�• Feeling “on edge” or stuck in fight-or-flight�• Difficulty falling or staying asleep�• Waking in the early hours�• Increased irritability�• Heavier or shorter cycles�• Worsening PMS-type symptoms

Progesterone interacts with the brain’s GABA receptors, which influence calmness and sleep regulation. When levels fluctuate, some women notice changes in stress tolerance and sleep quality.

It’s also important to understand that hormone levels shift throughout the cycle and can vary day to day. A single blood test may not always reflect how someone is feeling at that time.
Symptoms in perimenopause are often driven by fluctuation rather than simple deficiency. Context, cycle history, and pattern recognition are essential when interpreting both symptoms and lab results.

If you’re experiencing changes that don’t feel typical for you, a comprehensive and individualised assessment is important.
At Joy By Nature, we provide personalised consultations to explore symptoms, cycle patterns and contributing factors in a balanced and evidence-informed way.
