Period Predicted Fertile Ovulation

Past Cycles

ml is an estimate. Absorption varies by product (full pad ~30-50ml, tampon ~20-34ml, cup ~22-35ml, based on 2023 BMJ study). Menstrual cup markings are the most accurate. This is not a medical device. Consult a doctor if volume exceeds 80ml per cycle, large clots, or unusual color persists. Predicted dates (period, ovulation, fertile window) are estimates based on past logs, may be inaccurate, and must not be used as a method of contraception.

Track more than dates

PeriodVol estimates how much you actually bleed — in millilitres — each day and across your whole cycle.

Log with pictures

Pads, tampons, or a cup — just tap the picture that matches the size and how soaked it is. PeriodVol turns it into millilitres for you.

Know what's normal

Most cycles total around 30–40 ml. PeriodVol flags when a cycle passes 80 ml — the clinical marker for heavy bleeding — so you can talk to a doctor with real numbers.

See what's coming

Log a few cycles and PeriodVol predicts your next period, ovulation, and fertile window. Estimates only — not a form of contraception.
