Frequently asked questions
What is the difference between this and the ovulation calculator?
This page adds next-period and current-phase tracking, while the ovulation calculator focuses more directly on fertile timing.
Can this diagnose cycle problems?
No. It is a date-based planner, not a diagnostic tool for irregular or painful cycles.
Why do I need a period length field?
It helps estimate the period end date and gives a more useful current-phase view for planning.
