A childhood belief about getting pregnant

I used to believe that god would at some point make you pregnant, but he would tell you to get married first, and if you didn't get married when he told you to he would make you pregnant to let everyone know you didn't listen and that's why it was bad to be pregnant if you weren't married. Also that you could hold off being pregnant by praying a lot and being really holy, which is why grandmothers and nuns didn't get pregnant. Grandmothers were sort of pickled in holiness, so they never got pregnant, but sometimes nuns would pretend to be praying and they'd really be thinking about television, so after a few warnings god would make them pregnant to let everyone know they were slacking off on the praying which is why it was a huge bad thing if a nun got pregnant.
