The birth control pill and other hormonal contraception are popular. Menstrual periods are not. Hormonal contraception can be used to suppress menstruation — so why isn’t this method, called “continuous contraception,” more popular?
For decades, packets of birth control pills have typically contained 21 “active” pills and seven “placebo” pills. These placebos — sugar pills — trigger bleeding (which most people think of as a menstrual period, even though it’s technically called a withdrawal bleed). Because menstruation is natural, some people think this withdrawal bleed must somehow be healthier. But there are actually no health benefits — and it might also increase risk for pregnancy.
There is no reason to have a period when on the birth control pill — unless you want one.
Last month, British medical guidelines were revised to recommend continuous use of the birth control pill — that is, with no week-long “break” designed to trigger a withdrawal bleed. We could have been skipping our periods since the Pill was introduced in 1960 — so why is it only now that we are coming to see them as optional?
A flurry of recent articles has touted a rather conspiratorial claim: that the monthly bleed was included in an attempt to make the Pill more palatable to the pope. The Telegraph quoted reproductive health expert John Guillebaud: “John Rock devised [the week of placebo pills] because he hoped that the pope would accept the Pill and make it acceptable for Catholics to use. Rock thought if it did imitate the natural cycle then the pope would accept it.”
Many journalists, pundits, and bloggers have expressed outrage that we’ve been putting up with decades of unnecessary bleeding (and all the attendant pain, headaches, and missed work) just because of an unsuccessful attempt to appease the pope before most women of reproductive age were even born. But the history of the placebo week is more complicated. Continue reading
