The document opens with a full breakdown of spontaneous abortion types, classified by clinical presentation and cervical findings: Threatened: vaginal bleeding with closed cervix Inevitable: open cervix, no passage of tissue Incomplete: partial passage of products of conception Complete: full passage of tissue, cervix open Missed: fetal demise without symptoms, closed cervix Rh immunoglobulin is advised for Rh-negative women to prevent isoimmunization. Late pregnancy bleeding is discussed in detail: Abruptio placentae: presents with painful third-trimester bleeding, clinical diagnosis (not reliably visualized by ultrasound), often requiring C-section delivery, especially for concealed bleeding. Placenta previa: classic painless vaginal bleeding, diagnosed via ultrasound, and managed with C-section in most cases. It may resolve as the placenta migrates during gestation. Hypertensive disorders of pregnancy are clearly differentiated: Chronic hypertension: present before 20 weeks Pregnancy-induced hypertension (PIH): HTN after 20 weeks with no systemic signs Preeclampsia: HTN + proteinuria + edema after 20 weeks or up to 6 weeks postpartum May progress to HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets), a severe form requiring prompt recognition and management.
