Question: where do the hormones in birth control come from

title: Hormonal contraception
text: The progestogen only pill ( POP ) is taken once per day within the same three - hour window . Several different formulations of POP are marketed . A low - dose formulation is known as the minipill . Unlike COCPs , progestogen - only pills are taken every day with no breaks or placebos . For women not using ongoing hormonal contraception , progestogen - only pills may be taken after intercourse as emergency contraception . There are a number of dedicated products sold for this purpose .
