I think that we should drop NFP for FAM. (Fertility Awareness Method)
Because in essence, NFP is really FAM. It’s information naturally available and naturally observable. If you’re against NFP, you’re saying that we should be intentionally ignorant about our bodies. That somehow if you know you’re fertile and abstain, that’s a sin - but if you don’t know you’re fertile and you abstain, it’s not a sin.
Just a thought.
