What does the Pill do?

Answer:
"The Pill" was the very first almost 100%-sure precaution which a female could take to prevent conception through sexual intercourse with a male. "The Pill" tricked the female's body into "thinking" the female was already pregnant, thus prohibiting an additional conception.

On June 23, 1960, "The Pill" was approved by the FDA.

"The Pill" is composed of synthetic hormones that mimic the effects of actual estrogen and progestin in a women's body. "The Pill prevents ovulation, meaning that no new eggs are released by a woman who is taking "The Pill" as directed because her body is "tricked" into "believing" that a pregnancy has already taken place."
