Given the high unmet need for family planning during the post­partum period, this has raised the need to identification of the main barriers to provide methods of solutions. One of which is the need to integrate FP information and service provision during post natal care, child health care visits, and all levels of the health system. Objectives: This study aims to measure the rate of PPFP among women attending family medicine units in 6^th October city and to identify the effect of PPFP on pregnancy spacing as well as the main barriers facing its continuation. Methods: This study is a cross-sectional analytic study; it was conducted between July and October 2017 on married women in reproductive age attending three family medicine centers. Data were collected through a structured interviewed questionnaire based on concept definition of Postpartum Family Planning (PPFP) ; the prevention of unintended pregnancy and closely spaced pregnancies through the first 12 months following childbirth Results: About Sixty percent (59.4%) of women were between 25-35 years with a mean age of 30± 6.4 years. The rate of PPFP is 51.8%, more than half of studied women reported that" lack of knowledge on FP" is the main barrier to contraception use, followed by "desire to get more children" 42.2%.
