Deluxe CycleBeads are designed to help a woman track her cycle and know if she is on a day when pregnancy is likely or not. A reddish bead marks the first day of a woman’s cycle, the colored beads represent days when pregnancy is unlikely, and the white beads represent days when pregnancy is likely. A black marker is used to track the days. It is designed for women with cycles between 26 and 32 days long.
