How grave do your reasons need to be to use NFP to avoid pregancy?
The precise language the Church uses in Humanae Vitae discussing the kinds of reasons legitimating using NFP actually refers to "just reasons," "serious reasons," or "well-grounded reasons." The phrase "grave reason" is a mistranslation which gives the misleading impression that you have to be practically on death's doorstep or so broke you're eating dirt in order to use NFP to avoid.
In this episode, Sarah looks at the categories of reasons Humanae vitae mentions, and offers some specific examples.
She also recommends a way to pray together as husband and wife to get on the same page about your intention to avoid or try to achieve pregnancy.
