Periods while on the pill are artificial withdrawal bleeds, and it is possible to skip the break between pill packs without any risk to health or contraceptive efficacy.

The creator points to an accurate physiological fact: bleeding while taking the combined oral contraceptive pill is not a natural period, but a reaction to the hormonal withdrawal induced by the break or placebos. The historical origin of this break, designed to reassure users and religious authorities at the time by mimicking a natural cycle, is well documented by medical historians. Scientifically, systematic reviews (notably Cochrane) confirm that using the pill continuously does not alter its contraceptive efficacy and is considered safe for the health of users without contraindications. The main drawback noted by research is the increased frequency of 'spottings' (unscheduled bleeding) during the first few months, which is the most common side effect. While this practice is medically validated, it should ideally be discussed with a professional to ensure the absence of specific individual risks.
