Progestins are one of the female hormones.
They are necessary for the regulation of the menstrual cycle, as well as for the development of the milk-producing glands. If it is forgotten until the next day, stop taking the medication and use another method of birth control until a period starts, or the health care provider has determined that a pregnancy has not occurred. After a period has started, resume taking the medication at the normal time at the beginning of the period. This is different for birth control pills containing more than one hormone. In that case, skip the dose and take the next dose on schedule.
