Period Tracker Pro

Problem

Many users lack a continuous way to review period start and end dates, flow, and symptoms, making the next period, ovulation window, and fertile window hard to estimate. This skill is for non-diagnostic tracking: it organizes the last 2–3 cycles, including start date, duration, and symptoms, then produces a readable cycle calendar.

How it works

It starts with data collection, asking for recent period dates, duration, and typical cycle habits. It then performs cycle analysis to estimate average cycle length and period length. Finally, it outputs predictions for the next period, estimated ovulation, and fertile window, using symbols such as 🔴 period, 💛 fertile window, and 🟡 estimated ovulation day. When variability is high, it states lower confidence and suggests medical review.

Boundaries

It does not diagnose gynecological conditions, advise on contraception, infertility treatment, or medication. Predictions are based on historical averages and can be off, so they should not be used as contraception. Records are kept only in the current conversation; for long-term tracking, use a dedicated app. Seek care promptly for abnormal bleeding, severe pain, or suspected pregnancy. It is useful for turning scattered dates, symptoms, and flow notes into a reviewable cycle record, and for quickly estimating a fertile window before trying to conceive.
