Background: - delayed pregnancy return, refers to the inability of a couple to conceive after having 12 months of regular sexual intercourse without using any contraceptive method Family planning is the capability of individuals or couples to decide the desired number of their children and the spacing and timing of births through the use of contraception. In any case, women’s reproductive goals change at any moment of the woman’s fertile life; this is why the reversibility of the chosen method is especially important for them. Despite the advancement in contraceptive technologies and organized international effort over the last few decades; the concern of women who use reversible contraception related to time to return of fertility still remained unanswered Objective:-To assess proportion and Associated factors of delayed pregnancy return following discontinuation of reversible modern contraceptives among pregnant women attending antenatal care Methods: - Institution based cross-sectional study was done in December 2020. Systematic random sampling technique was used to collect data from 388 pregnant women using a structured questioner. Binary Logistic regression was used to assess the association between independent variables and dependent variables. The variables which have significant association were identified on the basis of P-value ≤0.05 and 95%Cl. Result: Three hundred eighty eight pregnant women were participated. This made the response rate of 91.5 %.Proportion of delayed pregnancy return after contraceptive discontinuation was 22.7 %( CI= 18.6-26.8). Prolonged use of contraceptive (AOR= 7.6 95%CI, 4.44-14.446), using Depo Provera (AOR=4.9 95%CI, 2.536-9.686) and women’s age (AOR=1.399 95% CI, 2.323- 19.679) are statistically significant association with delayed pregnancy return after contraceptive discontinuation. Conclusion: - This study found that proportion of delayed pregnancy return is 22.7%. Prolonged use of contraceptive, contraceptive type (using Depo Provera), and women’s age have highly statistically significant relationship with delayed pregnancy return after contraceptive discontinuation. Hence health professionals at health facility can use this finding during counseling of contraceptive users
