Jim Shelton's Pearls

Ongoing Monitoring of Cycle with SDM

P:OK, I see now how to make the initial screening for SDM practical. But once a woman starts SDM is it important for her to monitor her cycles on an ongoing basis to assess regularity and duration of her cycles?

R:Yes. The recommendation is that if a woman has 2 cycles out of the 26-32-day range within a year, she should not continue to use the method. This turns out to be about a quarter of women. The Cyclebeads are constructed to help women determine if a particular cycle falls outside the range.
