"The normalization of placebo pills and subsequent withdrawal bleeding means that even in 2017, many women do not know that extended cycle pills exist, let alone that menstrual suppression is a safe option. Combined with the fact that the percentage of schools teaching students about contraception has declined drastically since 2000, this means that many women are likely to stay in the dark about their options when it comes to choosing whether or not they want to bleed once a month."
