We present a qualitative interview study that examines what happens when things do not go as planned with digital contraception. Through an analysis of 27 interviews with ongoing users of digital contraception at the time of the study, we convey participants’ accounts of their experiences regarding unplanned pregnancies or use of emergency contraception to avoid an unplanned pregnancy. Our analysis considers participants’ sense-making processes, and notably how they attended to questions of risk and responsibility. Finally, we depict how these participants came to continue using digital contraception after these experiences. Our study connects to ongoing conversations on technological failures in personal informatics and safety-critical systems. We emphasise that failure and success should not be used as a binary classification of long-term users’ relationships with self-tracking technology, which are intimate and critical. Rather, the sustained relation with an intimate technology is composed by several ‘failures’ which are interpreted, acted upon, and, ultimately, overcome.

Designing technologies that clothe, adorn, or are otherwise placed on the body raises questions concerning the role they will play in dressing ourselves. We situate self-fashioning - or the process through which we stylise and present our bodies - as a complex practice where a series of social, material, and contextual factors shape how we present ourselves. Informed by reflective discussions and projective design tools, we contribute three critical points of departure for self-fashioning technologies: (i) Purposeful examining discomfort as an ongoing phenomenon, (ii) Supporting mimesis and visibility as qualities to be negotiated, and (iii) Envisioning the multiplicity of the body. We call for the design community to help devise fashionable technologies that are sensitive, caring, and responsive to the complexities of fashioning our bodies.

We present a large-scale, qualitative interview study that examines how an intimate technology within reproductive health comes to be chosen and trusted as a mode of contraception and how its use is shared between partners. We conducted 133 semi-structured interviews with primary users of Natural Cycles, focusing specifically on its use as a digital contraceptive. Our interpretive analysis, first, sheds light on perceptions of risks and benefits, along with how, and by whom, the decision to adopt Natural Cycles got made. Second, we discuss participants' and their partners' gradual development of trust in the system, and how this intertwines with interpersonal trust. Third, we consider the shared use of Natural Cycles, including partner involvement in temperature tracking, the sharing of intimate data, and navigating specific choices and risks regarding sex and contraception. We make a primarily empirical contribution to Computer Supported Cooperative Work (CSCW) research on shared uses of technology and the sharing of intimate data, and highlight avenues for future work to foster understanding of intimate technologies and their shared use in relational settings.

The ‘intimate horizons’ of algorithmic, self-tracking technologies have become increasingly important. These applications are no longer perceived as distant, instrumental entities, but offer a more affective and intimate experience. In this paper, we address the long-term experience of living with a digital contraception technology that utilizes self-tracking. We draw upon four design workshops with a total of 14 users of the app Natural Cycles to illustrate moments of ambivalent affects and oscillating relations. Based on our analysis, we concretize four dimensions of ambivalence in different scales and temporalities. We propose three strategies of designing with these unavoidable disruptions, conflicting feelings, and shifting relations to acknowledge users’ agentic engagements, nuanced dynamics of intimate self-tracking experiences, and users as embodied and affective beings. We contend that by attending to these existential ambivalences, digital contraceptive can become better configured to plural modes of life and long-term intimate relations that they engender.
