Through studying pregnant women's experience of prenatal screening and testing in Taiwan, this article argues that the collection of participant drawings provides a valuable contribution to feminist methodology where participants are seen as knowledgeable about their own situation. Drawings offer a context that enables us to analyse how participants (pregnant women and their partners) situated themselves in relation to their foetuses, technologies and families. This approach taught us an important methodological lesson, namely that methods always embody a particular political and epistemological location. Inspired by this line of thought, we suggest the concept enacting up, which combines the idea of enacting and the expression acting up to challenge scientific objectivity and biomedical practice while simultaneously giving voice to our participants.
