Perimenopause: What Your 40s' Cycle Changes Actually Mean

Perimenopause is the multi-year rehearsal before menopause, and its opening act is often mistaken for stress, luck, or "just getting older."

The classic early signs

• Cycles that quietly shorten (sometimes by 2–3 days)
• Heavier or lighter flows than your personal norm
• Sleep that fragments without an obvious cause
• PMS symptoms that intensify

Why tracking matters more now

Perimenopausal cycles are defined by variability. A tool that surfaces your changing baseline — rather than assuming a template — replaces "is this normal?" with "here's how my pattern is drifting."

The conversation to have

Bring patterns, not impressions, to your clinician: cycle lengths by month, flow changes, sleep and temperature notes. Femora's continuous signals make assembling that record effortless, across the transition that needs good data most.
