What about the rhythm method?
Many people incorrectly equate natural family planning wit the rhythm method. The “rhythm method” is an older form of natural family planning based on calendar calculations of previous menstrual cycles. Because this method does not allow for common changes and variation in the menstrual cycle, it is much less reliable than the mucus and symptothermal methods. Therefore, it is generally not recommended.
What about women with irregular cycles or who are breastfeeding?
It is common for women to have menstrual cycles that are irregular (either longer or shorter than 28 days). A woman who has irregular menstrual cycles will still be able to tell when she is ovulating by watching for the changes in her body. Special instructions have been developed for mothers who are breastfeeding their babies. Ask your teacher for these instructions if you are breastfeeding.
