Re: "falling" pregnant
Every time a man and a woman have sex, there is the possible result of pregnancy. There are two ways to "fall" pregnant. Immaculate conception, as the christians beleive, where Mary conceived and gave birth while still a virgin. Or...if the husbands sperm crawled out of his body, across the sheets and into the body of his wife then complete a swim, find the egg and fertilize it. Those are the only two ways one could "fall" pregnant.
The person I know was happy about "falling pregnant", she incorrectly described getting pregnant.
