Which condition commonly presents with cramping, lower abdominal pain, vaginal bleeding, and passage of tissue or clots?

• A. Spontaneous abortion
• B. Ectopic pregnancy
• C. Supine hypotensive syndrome
• D. Preeclampsia

Answer: (A)

The symptoms described—cramping and lower abdominal pain with vaginal bleeding and passage of tissue or clots—fit spontaneous abortion (pregnancy loss) most closely. The uterus contracting and then expelling tissue is the body’s way of ending a pregnancy that’s not viable, typically in the first trimester. The passage of tissue or clots is a telling sign that tissue from the pregnancy is being expelled.

Ectopic pregnancy can also cause pain and bleeding, but it often presents with unilateral abdominal/midepigastric pain and can lead to internal bleeding if rupture, rather than the clear passage of intrauterine tissue. Supine hypotensive syndrome occurs later in pregnancy when lying on the back reduces venous return, causing dizziness and hypotension, not tissue passage. Preeclampsia features high blood pressure and signs like severe headaches, visual changes, and edema, without tissue expulsion.

In a clinical setting, prioritize stabilization and obtain obstetric confirmation—vital signs, pregnancy test, and ultrasound—to determine viability and next steps.
