A 43-year-old woman sits hunched on the stretcher, the paper sheet beneath her already mottled dark red, one sneaker still on, one foot bare. She says she’s been “soaking through everything” for the last hour, and her voice wavers when she stands because the room tilts. The monitor shows a fast pulse; her skin is cool, and she keeps pressing her hand to her lower abdomen. The speculum tray is open beside you, but before you look, you need to decide how sick she is.

— What’s your move? Read on.

Before you read
  • What non-uterine source must you exclude before you call it “vaginal” bleeding?
  • Which patients need urgent gynecology and blood now, not later?

When to Think of It

Any abnormal uterine bleeding in a non-pregnant patient: soaking pads, intermenstrual bleeding, postcoital bleeding, bleeding after menopause, or bleeding with pallor, syncope, tachycardia, hypotension, or significant pain. Enter the diagnosis early in anyone with pelvic bleeding until pregnancy is excluded and a source is localized.

Sick or Not Sick

The single fork: hemodynamically stable vs unstable hemorrhage. Stable patients get focused localization and anemia workup; unstable patients get resuscitation, blood, and urgent source control.

The First Fifteen Minutes

  • If unstable, heavy ongoing bleeding, or symptomatic anemia → activate resuscitation, 2 large-bore IVs, type & cross, CBC/coags, and transfuse PRBCs 1 unit at a time as needed for hemorrhagic shock or ongoing blood loss, because oxygen-carrying capacity and perfusion are the immediate problem.
  • If hypotensive after initial crystalloid bolus → balanced crystalloid 1–2 L IV while blood is readied, because temporary intravascular support buys time.
  • If active heavy uterine bleeding and pregnancy excluded, consider tranexamic acid 1 g IV over 10 minutes (may repeat 1 g in 8 hours if needed; dosing protocols vary), because it inhibits fibrinolysis and can reduce blood loss.
  • If cervicovaginal source visualized and bleeding is focal (eg, cervical lesion, laceration) → direct pressure, topical hemostatic measures, and urgent procedural control; meds do not fix a mechanical bleed.
  • If severe pain with concern for ovarian torsion/cyst rupture coexisting with bleeding → fentanyl 50–100 mcg IV titrated for analgesia, because pain control improves exam and resuscitation tolerance without delaying definitive care.
  • If pregnant status is uncertain or not yet excluded → obtain urine/serum hCG immediately before anchoring on “non-pregnant” bleeding; if positive, the pathway changes completely.

Definitive Care & Disposition

Find the source: pelvic exam, speculum exam, bimanual exam, ultrasound when indicated, CBC, pregnancy test, and targeted STI/cervical testing when appropriate. Treat the cause — hormonal therapy for anovulatory bleeding when appropriate, gynecology for fibroids/endometrial pathology, procedural control for cervical or vaginal lesions, and admission for ongoing bleeding, transfusion requirement, syncope, or inability to ensure follow-up. Postmenopausal bleeding is cancer until proven otherwise and needs expedited gynecologic evaluation.

How This One Kills

Assuming “vaginal bleeding” is uterine and benign when it is actually ectopic pregnancy, cervical cancer, retained foreign body, or a hemorrhaging cervical/vaginal lesion. The classic failure mode is under-triage: the patient looks “just bleeding” until she collapses.
The Differential — What Else Looks Like This
  • Pregnancy-related bleeding — always excluded first with hCG; missing ectopic pregnancy can be fatal.
  • Hematuria — blood only appears vaginal until the patient urinates with a tampon/clean catch; confusing the source delays urologic or gynecologic workup.
  • Rectal bleeding — blood on wiping or in the toilet can be mistaken for vaginal bleeding; missing GI bleeding changes the entire pathway.
  • Abnormal uterine bleeding from anovulation — common and often stable, but confusing it with hemorrhage leads to either over-treatment or dangerous delay.

The Second-Day Story

Older patients may present with vague fatigue, exertional dyspnea, or “spotting” that turns out to be major blood loss; adolescents may minimize bleeding or normalize very heavy flow. Anticoagulated patients can have dramatic bleeding from minor structural lesions, and postmenopausal bleeding may be the only clue to malignancy. If the history is muddy, the vitals and hemoglobin trend matter more than the story.
Back to Our Patient
Back to our patient: the 43-year-old woman with soaked sheets and a fast pulse is a hemodynamically potentially unstable non-pregnant vaginal bleeding case until proven otherwise. She gets two large-bore IVs, type and cross, CBC/coags, immediate hCG, and rapid pelvic assessment while blood is readied; if bleeding remains brisk, TXA is reasonable and PRBCs are started based on symptoms, vitals, and ongoing loss. The key fork is stability: if she remains tachycardic or hypotensive, she stays in the resuscitation track with gynecology urgently at bedside; if stabilized, she still needs source localization and expedited follow-up or admission depending on the cause.
Patient Presentation to Attending
How you’d present this patient on the floor — tight, pertinent positives and negatives, no rambling
43-year-old woman with heavy vaginal bleeding and lower abdominal pressure for the past hour, soaking through pads and sheets at home. She denies known pregnancy, but pregnancy status is not yet confirmed; she reports lightheadedness on standing and crampy suprapubic pain without fever or trauma. On exam she is tachycardic, cool, and pale; abdomen is soft with suprapubic tenderness, and pelvic exam is pending. I’m concerned for significant abnormal vaginal bleeding with possible hemorrhage, so I’ve placed two large-bore IVs, sent CBC, coags, type and cross, and hCG, and I’m preparing fluids and blood while we localize the source and involve gynecology.

Study Directive

  • Practice a 60-second vaginal bleeding algorithm from memory: pregnancy test → stability → source localization → disposition.
  • Write out the resuscitation order set for unstable gynecologic bleeding, including when you would give TXA and when you would transfuse.
  • Review indications for urgent gynecology consult: unstable vitals, postmenopausal bleeding, suspected malignancy, or failure of initial control.
  • Compare uterine vs cervical/vaginal vs urinary vs rectal bleeding using one discriminating history question for each.
