Defines menopause
Menopause is confirmed after 12 months without a period when hormonal contraception is not affecting bleeding.
Cycles without alarms
Irregular cycles
Perimenopause can make cycle timing less predictable. Svarene gives those changes a place in the wider story of sleep, symptoms, mood, and treatments.

Cycles can change both ways
During perimenopause, cycles may lengthen, shorten, or be skipped; flow may also become lighter or heavier.
The useful comparison
A change from your own usual pattern is often more informative than comparison with a standard 28-day cycle.
What can change
Irregular does not always mean late.
Perimenopause is a transition marked by fluctuating ovarian hormones. A common early sign is that cycle timing changes: periods may arrive more or less often, be skipped, or differ in flow.
That variation deserves calm language. It can be expected during the transition, while still being worth documenting—especially when a change is new for you.
What to record
Dates matter. So do flow, symptoms, and context.
A useful record includes the first day of bleeding, approximate flow, spotting, pain, and any symptoms that arrived around the same time. Treatment or contraception changes can also affect what the pattern means.
- Cycle length and gaps between periods
- Changes in flow, spotting, or pain
- Sleep, mood, migraines, and vasomotor symptoms nearby
- Contraception, HRT, or other treatment changes
A useful boundary
Expected variation can still deserve clinical attention.
Bleeding that is unusually heavy, persistent, occurs after 12 months without a period, or worries you should be discussed with a qualified healthcare professional. Tracking helps describe what changed; it does not determine why.
