An unwanted pregnancy is a high-risk pregnancy that has psychological stress and impacts on nursing behavior during pregnancy. This requires coping efforts in order to handle stress. This study aims to analyze the coping behavior of mothers aged 35 years and over who experience unwanted pregnancies. This research is a qualitative research with a phenomenological approach. Data were obtained by means of in-depth interviews, focus group discussions and participatory observation on 21 informants consisting of pregnant women, families, health workers, and Posbunda cadres. Content analysis is used to identify topics or categories in data. The results showed that to overcome the problem two coping behaviors were carried out, namely coping focusing on emotions and coping focusing on problems. Coping behavior focuses on emotions, including praying, sleeping, sitting quietly outside the house, drinking coffee excessively, and getting fresh air. The coping behavior that focuses on the problem is telling the problem to find a solution and the consumption of herbs, soda, and drugs to abort the pregnancy. To support coping efforts, pregnant women get support from family, neighbors, friends, health workers, and Posbunda cadres. It is suggested to the Kassi-Kassi Health Center Makassar City to hold an intensive counseling program and health education regarding the correct use of contraceptive tools and methods to prevent unwanted pregnancies
