Aims and Objectives: 1. to study prevalence of various etiological factors involved in late pregnancy haemorrhage.  2. To find out relative frequency of various causes of bleeding during late pregnancy.  Materials and Methods: 1. this is observational retrospective study performed within span of 1 year (August 2014 to july 2015) 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  In this article, 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 groups- EARLY (< 20 weeks) & LATE (>20 weeks), and late 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. Late pregnancy bleeding due to abruption was 59%, 29.32% was due to placenta previa, 1.47% was due to vasa previa, 2.9% due to uterine rupture, 2.9% due to abnormal placentation and rest 4.41% constitutes causes due to distal genital tract/ gynaecological bleeding.  Conclusion: When pregnant women have bleeding, it may cause stress and anxiety for the mother-to-be about the outcome of pregnancy. So, it is necessary to diagnose and manage obstetric hemorrhage to prevent maternal or fetal mortalities and morbidities.
