I don’t think there are many people that just casually collect their basal body temps without the specific purpose of using that information in their family planning.
You might be wrong.
You have perhaps this impression because you are surrounded by the secular world/people and this knowledge is very diffused.
But there are women who chart even without the intention to use their information for family planning. Myself included. I start since 19 years old, for years. To know me better,to know where I am on my fertility, to anticipate periods. It can a routine thing. Yes, it was not done perfectly, because there was no hard goal.
Artificial birth control does not render conception impossible.
Sorry, but yes, it is the goal of contraception. Contraception can be failed of course, but it is not its goal, it is a failure. And failure as seen as a bad think by the doctors, all society and the couple.
. I believe that pretty much everyone who uses birth control (whether NFP or artificial) is generally aware that pregnancy is still possible if there has been sexual activity.
They more or less known it, but still execpt hat it work 100% (with the exception of someone pressure for a partner to not have children for eg…). They don’t think often or daily that it can failed and don’t plan their life on the possible failure.
If there is pregnancy, abortion is an option in most cases, for most couples. rates just depend on the countries, and people situation, and minds.
There is nothing open to life or oriented toward procreation in contraception. To said the other is untrue.
