Excellent post!

Upvoted and Resteemed! As you said, NFP is a great way of achieving and postponing pregnancy to de desired time of the couple, respecting the woman`s body and giving information to the woman about the lenght of her cycle and the average time of ovulation.

Also, some NFP as Basal Body Temperature are able to provide the woman with important information, for example, the basal temeperature of the woman should rise after she enters into the lutel phase, when this doesn´t happen, it might be a sign of ovulation not taking place.

God Bless Us All!
