Bleeding in first trimester of pregnancy poses a risk to embryo. It can be a natural symptom of implantation, sign of spontaneous abortion, or of pathologic condition like ectopic pregnancy/ gestational trophoblastic illness.4 Aim: To assess the etiology and outcome of first trimester bleeding.

Objectives: (1) To study the etiology for first trimester bleeding. (2) To study the incidence of various etiological factors.

Settings and design: This is the prospective observational study carried out in a tertiary health care centre over 2 years from October 2019 to october 2021.

Materials and methods: This study was conducted on women with complaints of vaginal bleeding in first trimester of pregnancy. The methodology were explained to the women and valid informed written consent was recorded. The ethical clearance was obtained from ethical review committee of the tertiary care centre. After taking a detailed history and physical examination, the patient will undergo a urine pregnancy test, on confirmation she will be sent for a TVS scan depending upon the USG report further management and follow-up will be decided.

Conclusion: Bleeding in first trimester doesn’t necessarily lead to miscarriage, but causes anxiety to the patient. Women and obstetricians should consider the outcome of continued pregnancies after the first trimester bleeding when planning antenatal care and clinical interventions. We need more researches on this to improve our better understanding and knowledge so that we can better plan the continued pregnancy as well as council the patient in better way.
