I am always happy to see the MSM cover NFP, even if they insist on calling it contraception when it is not. It does not act against conception. It helps a couple to understand their mutual fertility and time relations accordingly.
However, it is even better when there is also another MSM source which shows that the birth control pill has become less effective. Apparently, the smaller dose of hormones required to diminish the hazardous side effects (blood clots, breast cancer, and the like) has caused an increase in the failure rate. I hope to still be teaching NFP when our chart of effectiveness shows that the birth control pill is 98% effective and STM is 99% effective.
