Background: The Billings approach is a fertility awareness-based approach that relies on vulvar feelings and discharge appearance to identify patterns of fertility and infertility. Aim: Assess level of awareness and attitudes of child bearing women regarding billing ovulation methods as a family planning method. Methods: Descriptive cross sectional research design was used in this study. It was conducted at postpartum department, Women Health Hospital, Assiut University. Sample: A convenience sample of a total 360 women involved in the study. Two tools were used; structured interview questionnaire and likert scale. Results: 76.1%, 16.1% and 7.8% of the studied women had a poor, average and good knowledge level about billing ovulation method respectively. About 62.5% and 37.5% of them had positive and negative attitude regarding using BOM. Conclusion: Most of postpartum mothers had little awareness and a favorable attitude toward utilizing BOM. Recommendations: Campaigns should be run in communities to raise awareness of billing ovulation method and expand knowledge of it among both literate and illiterate postpartum in order to decrease the size of extended families.
