CycleBeads, a color-coded string of beads that represents the days of a woman's cycle, helps an individual use the Standard Days Method, by helping her track her cycle days. Starting the first day of her period, she moves a band to the red bead then to a new bead every day. The color of the bead lets her know if today is a day she is highly likely to be fertile or not. Couples use condoms or barrier methods to prevent pregnancy on fertile days. An efficacy trial found that CycleBeads was more than 95% effective at preventing pregnancy with correct use and approximately 88% effective with typical use among women who reported recent cycles of 26–32 days. While this is similar or better than the efficacy of most other
Natural Family Planning methods. its perfect use is significantly less effective than many other modern
birth control methods and
Long-acting reversible contraceptives. Women can use CycleBeads to plan pregnancy as well. Couples target those days where the bead colour indicates fertility is highest for intercourse to conceive a child. ==Main Drawbacks==
