What are birth control pills?
Birth control pills (oral contraceptives) are hormones taken to prevent pregnancy and help with managing disruptive menstrual periods. The hormones (Estrogen (E) + Progestin (P)) in the pills change a woman’s natural hormone levels and prevent her ovaries from releasing an egg each month. They also cause a thickening of the mucus on the cervix and change the lining of the uterus. The thickened mucus on the cervix makes it hard for sperm to enter the uterus. The most commonly used pills are combined estrogen+progesterone (E+P) pills. There is also a progesterone (P) only pill that you take every day and does not contain placebo pills, sometimes referred to as the “mini pill.” There are two different vaginal ring products that deliver the hormones through the vagina but carry the same risk and benefits of oral contraceptives.
How are the pills used?
The combined E+P pills usually come in a package of 28 pills. Depending on the brand of pills your pack may have 21 E+P pills with 7 placebos, or 24 E+P pills with 4 placebos. Menses typically occur when taking the placebo pills. They are also available in 91 day-pill packs with goal of menses every three months. You and your health care provider will decide which type is best for you.
