Failure to take pills during the placebo week does not impact the effectiveness of the pill, provided that daily ingestion of active pills is resumed at the end of the week.The placebo, or hormone-free, week in the 28-day pill package simulates an average menstrual cycle, though the hormonal events during a pill cycle are significantly different from those of a normal ovulatory menstrual cycle. Because the pill suppresses ovulation (to be discussed more in the Mechanism of action section), birth control users do not have true menstrual periods. Instead, it is the lack of hormones for a week that causes a withdrawal bleed. The withdrawal bleeding that occurs during the break from active pills has been thought to be reassuring, a physical confirmation of not being pregnant. The withdrawal bleeding is also predictable. Unexpected breakthrough bleeding can be a possible side effect of longer term active regimens.Since it is not uncommon for menstruating women to become anemic, some placebo pills may contain an iron supplement. This replenishes iron stores that may become depleted during menstruation. As well, birth control pills, such as COCPs, are sometimes fortified with folic acid as it is recommended to take folic acid supplementation in the months prior to pregnancy to decrease the likelihood of neural tube defect in infants.
The FDA Advisory Committee made comments about this, that if there wasnt enough evidence to indicate whether or not these pills were related to the development of cancer, and I think thats still thin; you have to be cautious about them, but I dont think there is clear evidence, either one way or the other, that they do or dont cause cancer. Another physician, Dr. Roy Hertz of the Population Council, said that anyone who takes this should know of "our knowledge and ignorance in these matters" and that all women should be made aware of this so they can decide to take the pill or not.The Secretary of Health, Education, and Welfare at the time, Robert Finch, announced the federal government had accepted a compromise warning statement which would accompany all sales of birth control pills. Result on popular culture
The introduction of the birth control pill in 1960 allowed more women to find employment opportunities and further their education. As a result of women getting more jobs and an education, their husbands had to start taking over household tasks like cooking. Wanting to stop the change that was occurring in terms of gender norms in an American household, many films, television shows, and other popular culture items portrayed what an ideal American family should be. Below are listed some examples:
