Differential Diagnosis for Bleeding at 10 Weeks Pregnant

  • Single most likely diagnosis
    • Threatened abortion: This is the most common cause of bleeding in early pregnancy, accounting for up to 50% of cases. It is characterized by vaginal bleeding with or without abdominal cramps, but the cervix remains closed.
  • Other Likely diagnoses
    • Inevitable abortion: This condition is characterized by vaginal bleeding and abdominal cramps, with the cervix open, indicating that a miscarriage is imminent.
    • Missed abortion: This occurs when the fetus has died but remains in the uterus, often presenting with bleeding and a closed cervix.
    • Ectopic pregnancy: Although less common, ectopic pregnancy is a significant concern, especially if there is associated abdominal pain and a history of infertility or previous ectopic pregnancy.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Placenta previa: A condition where the placenta partially or completely covers the cervix, which can cause severe bleeding and is life-threatening if not promptly diagnosed and managed.
    • Molar pregnancy: A rare condition where an abnormal placenta develops, which can cause bleeding, and if not treated, can lead to serious complications, including cancer.
    • Uterine rupture: Although extremely rare in early pregnancy, uterine rupture can occur, especially in women with a history of uterine surgery, and is life-threatening.
  • Rare diagnoses
    • Cervical polyps or cervical cancer: These conditions can cause bleeding during pregnancy but are less common causes compared to the other diagnoses listed.
    • Vaginal or vulvar trauma: Trauma to the vagina or vulva can cause bleeding and should be considered, especially if there is a history of trauma or sexual assault.
