The chance of miscarriage after bleeding and a live fetus at scan has not previously been defined precisely. The purpose of this study was to evaluate the outcome of early pregnancies with a viable singleton fetus that had been complicated by bleeding. A prospective study was performed on 370 women with a singleton live fetus who had presented to the early pregnancy assessment clinic (EPAC) with vaginal bleeding. Women were grouped into light, moderate and heavy loss according to the self-assessed degree of vaginal bleeding. The women were also categorised according to the presence or absence of an intrauterine haematoma. The overall spontaneous miscarriage rate in the study was 11.1%; almost 90% of pregnancies continued to viability. Women with moderate or heavy bleeding had more than twice the rate of miscarriage compared with those with light bleeding. A total of 14% of the women had an intrauterine haematoma and those women were 2.6 times more likely to miscarry than those without (23% vs 9%). This relationship appeared to hold true even after controlling for blood loss. The data presented can be used to guide women with a live fetus about the chance of miscarriage after an episode of vaginal bleeding. We propose that a large multi-centre study should be undertaken to define precisely the risk miscarriage for each gestational week according to a range of clinical and ultrasound characteristics.","is_dataset_classified":null,"base_score":3.9889840465642745,"endowment":3.9889840465642745,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"17130030","pmcid":null,"openalex_id":"https://openalex.org/W2121096509","authors":[],"funders":[],"total_grants":0,"fwci":1.938,"citation_percentile":0.86531626,"influential_citations":0,"citation_trend":[{"year":2012,"count":2},{"year":2013,"count":3},{"year":2014,"count":2},{"year":2015,"count":5},{"year":2016,"count":4},{"year":2017,"count":1},{"year":2018,"count":3},{"year":2019,"count":2},{"year":2020,"count":7},{"year":2021,"count":4},{"year":2022,"count":4},{"year":2023,"count":3},{"year":2024,"count":3},{"year":2025,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://www.tandfonline.com/doi/pdf/10.1080/01443610600984412","host_type":"publisher"},{"url":"https://doi.org/10.1080/01443610600984412","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/17130030","host_type":"repository"}],"fields_of_study":["Ectopic Pregnancy Diagnosis and Management","Maternal and fetal healthcare","Gestational Trophoblastic Disease Studies"],"mesh_terms":["Abortion, Spontaneous","Adolescent","Adult","Female","Humans","Pregnancy","Pregnancy Complications, Cardiovascular","Pregnancy Trimester, First","Uterine Hemorrhage","Ultrasonography, Prenatal"],"keywords":["Medicine","Miscarriage","Obstetrics","Vaginal bleeding","Pregnancy","Fetus","Singleton","Gestation","Gestational age","Live birth","Gestational sac","Gynecology","Products of conception","Prospective cohort study","Surgery"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T07:31:05.004479Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
