Can The DivaCup be used for light and heavy flows?
A. The DivaCup works very well for women with light or heavy flows. The DivaCup holds one full ounce and the average women only flows about three to four ounces in her entire cycle. For most women, the cup is not even half full after 12 hours. We always recommend you empty the cup, wash, rinse it, and reinsert it at least every 12 hours (2 times a day) even if your flow is light. Women with heavy flows will simply need to empty the cup more often. The convenient ounces and milliliters measurement feature allows women to actually keep track of flow and accurately report flow details to their health professional.
