Combined oral contraceptive pills
All contain the estrogen ethinyl estradiol, although in varying amounts, and one of a number of different progesterones. They are taken for 21 days with then a 7 day gap during which a withdrawal bleed (often, but incorrectly, referred to as a menstrual period) occurs. These differ in the amount of estrogen given, and whether they are monophasic (only one dose of estrogen and progesterone during the 21 days) or multiphasic (varying doses).
These are given as 21 tablets of estrogen and progesterone, followed by 7 tablets of placebo. Different formulations contain different amounts of estrogen and progesterone:
