The main division is between combined oral contraceptive pills, containing both synthetic estrogens and progestogens (progestins), and progestogen only pills (mini-pills). Combined oral contraceptive pills also come in varying types, including varying doses of estrogen, and whether the dose of estrogen or progestogen changes from week to week.
