The combination pill is a type of birth control pill. It's a hormonal method of oral contraception that is taken daily to prevent pregnancy. The combination pill contains the hormones estrogen and progesterone (progestin). These hormones stop the ovaries from releasing an egg, thicken the cervical mucus, and thin out the lining of the uterus. This prevents pregnancy from occurring by keeping the egg and sperm from reaching each other and implanting in the uterus. When taken correctly, the combination pill is up to 99% effective.
