Period Predicted Fertile Ovulation

Past Cycles

ml is an estimate of blood lost, not total fluid. A fully soaked regular pad or tampon is about 5ml; large/overnight pads hold more (roughly 10-15ml). Menstrual cup markings are the most accurate way to measure. 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.

How much do you bleed?

Never measured it. Never compared it. Never known what's normal. Most people haven't — PeriodVol finally shows you, in real millilitres.

No numbers. Just tap.

Pads, tampons, or a cup — tap the picture that matches what you used and how soaked it was. PeriodVol does the millilitre math for you.

Spot a heavy cycle

Most cycles are 30–40 ml. Cross 80 ml — the clinical line for heavy bleeding — and PeriodVol flags it, so you see a doctor with real numbers, not a guess.

Never caught off guard

After a few cycles, PeriodVol predicts your next period, ovulation, and fertile window — right on your calendar. Estimates only — not contraception.
