Pill
Most commonly known as “the Pill,” combination birth control pills contain both progesterone and estrogen. Working together, these hormones stop ovulation and prevent sperm from reaching and fertilizing the egg.
Progesterone-only pills, sometimes called “mini pills,” are birth control pills that don’t contain the estrogen hormone. They work by creating changes in the cervix and uterus, to prevent sperm from reaching and fertilizing the egg.
