Daily How Much

Most standard tampons hold about 6–18 mL of menstrual flow, depending on the absorbency label and how fully it’s saturated.

Most cycles shed about 30–40 mL of blood in total, while blood loss above 80 mL is commonly used as a heavy-bleeding cutoff.

Most periods add up to about 30–80 mL of blood total, with heavier flow often showing up as frequent pad or tampon changes or clots.

Blood volume often rises about 30–50% during pregnancy, with the peak usually in the third trimester.

Most periods involve around 30–40 mL of blood total, with heavier bleeding often defined at more than 80 mL across one cycle.

Most menstrual cups hold 15–35 mL, while larger cups can reach 40–50 mL when filled to the rim.

Most full-size period pads hold about 5–15 mL in day-to-day wear, while longer overnight pads often handle 15–30 mL before leaks become likely.

A “regular” tampon is built to absorb about 6–9 grams of test fluid, which often lines up with about 6–9 mL of menstrual flow.

Most adults carry around 4.5–5.5 liters of blood, with the total shifting with body size, pregnancy, and day-to-day fluid balance.

A female mosquito usually drinks about 1–10 microliters of blood per meal, with many species clustering near 3–5 microliters.
