Aims and Objectives: (1) To study prevalence of various etiological factors involved in early pregnancy haemorrhage. (2) To find out relative frequency of various causes of bleeding during early pregnancy. Materials and Methods: (1) This is observational retrospective study performed within span of 2 years (August 2014 to july 2016) in Department of Obstetrics and Gynaecology in ACPM Medical college, Dhule. (2) Total number of 200 women with bleeding per vaginum during pregnancy were enrolled in the study. The patients who presented with vaginal bleeding were divided into: 1. Early pregnancy bleeding < 20 weeks. 2. Late pregnancy bleeding > 20 weeks. Since the demographic profile, etiology, risk factors involved, maternal & perinatal morbidities and mortalities associated with early and late pregnancy group are drastically different, so the cases in this study are divided into two groupsEARLY (< 20 weeks) & LATE (>20 weeks). In this first article, early pregnancy group studied separately in terms of all variables. Results: In this study, 66% patients presented with early pregnancy bleeding and 34% with late pregnancy bleeding. Early pregnancy bleeding due to abortion was 72.7%, 4.54% was due to molar pregnancy, 10.6% was due to ectopic pregnancy and rest 6.81% constitutes causes due to cervical factors. Conclusion: Preventable maternal death is greatest tragedy in obstetrics. Vaginal bleeding at any stage of pregnancy is an alarming event and can be potentially life threatening situation. Efforts to improve geographical access, referral services and quality of comprehensive emergency obstetric care are required to improve maternal outcome.
