Discovering a pregnancy after 30 weeks: a qualitative study on explanations for unperceived pregnancy

"Unperceived pregnancy" names the phenomenon when a person becomes pregnant unintentionally and is not aware of being pregnant. Scientific explanations are roughly based on two hypotheses: psychological and physiological. We aim to gain a better understanding of unperceived pregnancy by studying the perspectives of people who experienced an unperceived pregnancy and obstetric professionals. Seventeen semi-structured interviews were conducted: eight with women who had experienced an unperceived pregnancy (≥30 weeks' gestation), six with midwives, and three with gynecologists. Our findings show that women's explanations for not noticing their pregnancy center around the absence of pregnancy symptoms. The failure to recognize more subtle signs of pregnancy was enforced by inattention, physical distractions, and psychological factors. In contrast, psychological explanations are dominant among obstetric professionals. Our study demonstrates a discrepancy in the explanations provided by women who had experienced an unperceived pregnancy and obstetric professionals. Potentially, this could result in people being unheard and misunderstood. We recommend that future research moves beyond a focus on "denial of pregnancy" to consider both psychological and physiological factors, and how these could potentially interrelate. This broadened approach will enhance our understanding of unperceived pregnancy and can contribute to improved counseling by obstetric professionals.
