Abstract     A case control study was undertaken investigating risk factors for conceptions early postpartum. We have compared reproductive behaviour of women who experienced an unwanted pregnancy within the first year postpartum (cases) with women who did not become pregnant (controls) within the same period. The data were analyzed using four different statistical methods - conditional logistic regression for matched pairs, logistic regression for unmatched data, proportional hazard model and discrete Cox regression. The advantages and disadvantages of each method are described. We have compared how do our data fit with the Bellagio Consensus Statement from 1988 which was based on prospectively conducted studies. Time postparturn, time of menses resumption and contraceptive use postpartum were shown to be the most important risk factors for conception early postpartum. Women who experienced an unwanted pregnancy were less educated and of higher parity. Nationality, education, breastfeeding and smoking habits were associated with risk factors only and thus having an indirect impact on the risk of conception early postpartum. For our women it would be possible to extend the Bellagio Consensus Statement up to 32 weeks postpartum and during supplementation. In our population women should adopt reliable contraceptive methods once menses have returned or breastfeeding is terminated. After the baby is more than 32 weeks old, reliable contraception is to be initiated even in the case of lactational amenorrhea. Due to short breastfeeding practice and short duration of amenorrhea, postpartum. counseling about contraception is advised at the time of postpartum hospitalization, by the latest at the time of the first check up six weeks
