During your period, you may have some light days when you’re barely bleeding at all, and then some days where your bleeding is heavier. Your period flow (volume) is the amount of blood that comes out, and the easiest way to measure it is by noting how often you need to change your period products. Your flow may be light, regular, heavy, or very heavy. You’ll probably need to change your pad, tampon, or menstrual cup about 3–6 times a day.

The average volume of menstrual blood is only between 3-8 tablespoons for your entire period.
