FAQs: Period Tracker

Our tool averages your last three cycle lengths and adjusts for patterns. For example, if your cycles were 32, 28, and 35 days, it predicts based on a 31-day average.

Use the Ovulation Calculator feature, which estimates fertile days. Safe days are typically outside this window, but consult a doctor for contraception advice.

Your LMP is the first day of your last period. Enter this date into the tool, and it’ll handle the rest.

Use our calculator alongside a journal or app to log symptoms, flow, and cycle lengths. Consistency helps!
