We occasionally hear the question “isn't CycleBeads just the rhythm method?" The answer is NO. CycleBeads, and the Standard Days Method on which it is based, are very different from the so-called “rhythm method”, a method which is vaguely understood, not well defined, confusing to use, and largely untested.
The confusion most likely comes from the fact that CycleBeads and the rhythm method are both considered “calendar-based natural family planning methods”. That is where the similarities end.
