Can you skip your sugar pills?

Illustrated by Hannah Boonstra, BSc Executive Summary: Yes, the research indicates that it is safe to skip your sugar pill. Keep reading for a more in-depth exploration of the research of skipping sugar pills and the possible pros and cons.

I am a white settler cisgender woman living on the traditional, ancestral and unceded territory of the Coast Salish, Musqueam, Tsleil-Waututh, Squamish, Stó:lō, Stz’uminus peoples in what is now known as Vancouver, BC. The purpose of this article is to give clear, scientifically-backed answers regarding oral contraceptive pills (OCP) and its use. While this post intends to give clear information regarding all OCP users, it is important to note that Black, Indigenous, People of Colour (BIPOC), transgender, nonbinary & gender fluid OCP users have been historically underrepresented in OCP research. I acknowledge my experience as a white, cisgender woman shapes how I interpret OCP research and I hope to continuously learn in the case of error or misrepresentation. I would also like to acknowledge that I am not a medical professional and the content of this article is a summary of relevant academic publishings. Thanks for reading! :)

Oral contraceptive pills (OCP), also known as birth control pills, are one of the most common hormonal birth control methods, used by over 150 million women worldwide (1*). OCPs can be used by people with uteruses, of any gender identity, as well as by individuals receiving gender-affirming hormone therapy (e.g. testosterone) (2). Most OCP-users take a combined-hormone oral contraceptive (OC) daily for 21 days, which contains the synthetic hormones, estrogen and progestin. Different brands of OCPs have different cycle lengths. The cycles vary from 21 - 84 days (3). After taking all "active" pills, most OCPs include "sugar" or placebo pills, which do not contain active hormones. At this time, bleeding occurs. But what if you don’t take those sugar pills? Can you skip your periods?


Originally, OCPs did not include sugar pills and instead, women were instructed to take the pills for three weeks then take a break for a week to allow for bleeding, to mimic a “natural menstrual cycle”. Sugar pills were added to this regimen to ensure users would remember to take the pills. However, the bleeding that occurs in the sugar pill week is actually not a physiological period (i.e. the shedding of uterine lining) but is actually known as “withdrawal bleeding” from the lack of hormones (4). Medically, there is not a reason to cyclically endure withdrawal bleeding every month (you can read more into the history in this article*) (5). Nonetheless, the sugar pills have stuck around as a way to help the OCP-user maintain the routine of taking a pill everyday, and some brands include dietary supplements in the sugar pill, such as iron (6).


What if we want to go out and have a good time without having to pack away menstrual products like a squirrel heading into winter? Is it okay if I skip my sugar pill and take active pills? Will my uterine lining build up and gush out of me when I do finally take the sugar pills? Fear not, you will not become a bloody Niagara Falls. The hormone, progestin, prevents the uterine lining, or endometrium, from building up indefinitely throughout your cycle. Multiple studies have tested continuous OCP use, confirming efficacy of birth control and safety (see review by 3*). In most participants, the most frequent issue with continuous OCP use was breakthrough bleeding in the first 3 months of continuous use. Continued use of OCPs may gradually thicken the uterine lining and this may slough away in the form of spotting. However, by the end of a year of continuous OCP use, breakthrough bleeding was significantly less frequent (7*). This just means you may find yourself with irregular and small amounts of bleeding during the initial months of skipping the sugar pills.

As long as you're consistent with taking your daily dose as directed by your doctor, you are not increasing your risk of pregnancy, even when you're skipping your sugar pills. In fact, in two studies examining extended OCP use, the continuous-users showed a decrease in pregnancy rate versus individuals using a standard sugar pill cycle (8*-9*). This could be a result of better compliance (i.e. you get into the habit of taking the pill everyday, whereas with sugar pills it doesn't matter if you skip those). Also the constant hormone levels doesn't allow for accidental ovulation. Yay!

Actually, some benefits of continuous use of active OCPs (i.e. skipping your sugar pills) can include decreased incidences of pelvic pain, headaches, bloating, breast tenderness (for those who usually experience these symptoms in the sugar pill week). Additionally, continuous OCP use can help manage symptoms of premenstrual dysphoric disorder (PMDD), endometriosis and polycystic ovary syndrome (PCOS) (10*).

Some disadvantages of continuous OCP use have not been identified as researchers do not have much data regarding long-term safety. However, in a systematic review of continuous OCP use studies, continuous OCP use was found to be as safe as standard cycle OCP use (11*). Similarly, research has not found any significant impact on fertility with continuous OCP use (12*). Additionally, breakthrough bleeding could be annoying if you decide to wear white pants one day - though this is going to depend on you, your body, and your pill (3).

Cost-wise, you may spend more money on OCPs when skipping your sugar pills because you're using more packages in a year, but you would also save money on sanitary products and potentially missed work days, but that's a personal cost-benefit analysis to consider (10).

Ultimately, the science suggests that not bleeding every month is a viable option for all you uterus-havers out there!

We acknowledge that our actions contribute to the land we live on, and as such we are tasked to be caretakers of this land and the people that inhabit it. On behalf of the individuals of immigrant and settler Canadian descent who are present on our team, we acknowledge that our positions on health, and our accessibility to healthcare, have been largely shaped by our own lived experiences which encompass many privileges. We are committed to continually evaluate & decolonize our practices, and doing our best to incorporate the lived experiences of the land defenders and protectors within our work. We plan to use our platform to be inclusive of all womxn who call the geographical confines of what is currently known as Canada, home, and hope to build our organization to represent and support womxn of all identities including but not limited to queer, trans, two-spirit, and non-binary folx, as well as those that identify as Black, Indigenous, or Womxn of Colour. As an organization, we will try our utmost best to ensure that only individuals with lived experiences are speaking on behalf of their communities, while still recognizing that communities of colour and the LGBTQ2S+ community, are not a monolith. While each member of missINFORMED brings their own experiences, education and expertise, we are always motivated to keep learning and to keep expanding our repertoire and knowledge capacity. We hope that through this platform, we can build an inclusive, diverse and equitable community of empowered and informed womxn.

Womxn, in our use of the word, refers to those who identify as cis or trans women, folx assigned female at birth and those who are comfortable in a space that centres on the experiences of women. Gender diverse folx are welcome in our space and we hope to provide them with the necessary health resources to inform and educate their decisions.
