What a crock. God did NOT make women constantly fertile - they naturally have quite long periods of infertility each month. Some, like my older sister, go for years (in her case about a decade) being naturally infertile (no ABC of any kind) and then boom, the kids come. More than that, God’s will for all married folk is monogamy. All of which militates against the idea that we’re designed to simply squeeze out maximum kids in minimum time.
But God’s will for the unmarried is total celibacy - which is not only not wrong (Jesus Himself was celibate, as were Mary and Joseph), but is praised by Him (‘those who make themselves eunuchs for the sake of the kingdom’.)
If you know what a eunuch is, eunuchs were incapable of sex (hence their being used in later centuries to guard royal harems). So while abstaining from sex is laudable, Christ nowhere mentions or approves of those who have sex but avoid the children which are the natural result. It’s the abstaining from sex that is praiseworthy!
But there’s much more to it than that.
You really need to learn and understand the critical difference between
a) on the one hand sinfully putting up an ***artificial ***chemical or synthetic barrier (ABC) which interferes with the perfectly normal and healthy God-ordained bodily reproductive process, and interferes with God’s own plans for the human species moreover, and
b) on the other hand a process (NFP) which fully co-operates with and is integrated with both nature and God’s plan. Which amounts to no more than knowing and taking advantage of the natural periods of infertility that God Himself in His wisdom grants us, and which moreover has the healthy sid-effect of requiring a Christlike self-control and self-denial from both husband and wife.
Can’t you see that the first is simply you imposing your will upon your fertility no matter what God thinks or wants for you, while the second is adhering to God’s own designs for the human reproductive cycle in general and your own in particular?
