The most frequent reasons mentioned by the participants in this study for failure to avoid unintended pregnancy were contraceptive method failure, using breastfeeding, lack of awareness, and husband/partner disapproval. Husband disapproval was reported by less than one third (13.7%) which is analogous with a study conducted in Harar (11.6%) [6]. This is may be due to men’s desire for more children than women in both areas because of different socio-cultural contexts as mentioned above. Method failure in the current study was much higher than that of Harar (31.3% vs. 11.1%). On the other hand, lack of awareness in the present study was much lower than that of Harar [22.1% vs. 70.6%, 5]. This may be due to a timely increase in awareness and utilization of modern contraceptives [6].
