The Effect of Mobile App Counseling on Postpartum Contraception Choices and Use

The goal of this clinical trial is to determine the effect of a mobile application developed for postpartum contraception counseling on contraception method choice and use among postpartum women aged 18 and older. The main hypotheses it aims to answer are; * H1: Among postpartum women, the use of highly effective contraceptive methods is higher in the group using a mobile application for contraception counseling compared to the group receiving face-to-face counseling. * H2: Among postpartum women, the use of highly effective contraceptive methods is higher in the group using a mobile application for contraception counseling compared to the group receiving routine postpartum care. * H3: Contraceptive method continuation and satisfaction are higher in the group using a mobile application for postpartum contraception counseling compared to the group receiving face-to-face counseling. * H4: Contraceptive method continuation and satisfaction are higher in the group using a mobile application for postpartum contraception counseling compared to the group receiving routine postpartum care. Researchers will compare three groups: 1. Group receiving contraception counseling via mobile app: Women in this group will have a postpartum contraception counseling mobile application installed on their phones and will use the application for 12 weeks. 2. Group receiving face-to-face contraception counseling: These women will receive face-to-face contraception counseling during the initial encounter, and an educational booklet will be provided at the end of the counseling session. 3. Control group: Women in this group will receive routine postpartum care. All groups will be followed up at three time points: the initial encounter, the first follow-up, and the second follow-up. The initial encounter will be conducted face-to-face at the hospital within the first 5 days postpartum. The first follow-up will take place by phone at 6 weeks postpartum, and the second follow-up will be cond
