♀ Important: Always enter the first day of bleeding — not the last day and not the day you expect it. Cycle length is measured from Day 1 of one period to Day 1 of the next. More dates entered = more accurate analysis. Minimum 2 dates required, 4 or more recommended.
Please enter at least 2 period start dates, with the most recent date first.

Cycle classification based on FIGO 2011 Menstrual Cycle Terminology
(Munro MG et al., Int J Gynaecol Obstet 2012;113(1):3–13).
Normal cycle length: 24–38 days. Regular cycle: variation < 8 days between shortest
and longest cycle over at least 3 cycles. This tool does not diagnose any medical condition.
Persistent irregularity, very heavy bleeding, or cycles outside the normal range should be
evaluated by a qualified gynaecologist. All results are estimates based on entered data.
