Which family planning methods are fertility awareness-based methods?


Standard Days Method®

The Standard Days Method® (SDM) is based on monitoring the days of a woman's menstrual cycle. Appropriate for women who usually have menstrual cycles between 26 and 32 days long, the method identifies days 8 through 19 as the fertile days. To use the method, the woman tracks her menstrual cycle and avoids unprotected sex on the fertile days. A woman can use CycleBeads®, a color-coded string of beads, to help track the days of her menstrual cycle and to see which days she is most likely to get pregnant.


CycleBeads®, a color-coded string of beads, facilitates use of the Standard Days Method® by helping women track their menstrual cycle and identify their fertile days. As described below, each bead represents a day of a woman’s menstrual cycle.
