Faint Positive Pregnancy Test Followed by Bleeding: Chemical Pregnancy, Miscarriage, or Viable Pregnancy?

A faint positive home test then bleeding (>1 week later) suggests:

• Chemical pregnancy: Very early loss before ultrasound detection; hCG rises then falls.
• Early miscarriage: Passing decidua (uterine lining) or clots.
• Viable pregnancy: Bleeding from implantation, subchorionic hematoma, or cervical irritation.

Red Flags—Seek Emergency Care

• Heavy bleeding (soaking pads)
• Severe abdominal pain
• Fever, chills, dizziness, weakness

Next Steps

1. Quantitative blood hCG (repeat in 48h to assess trend).
2. Transvaginal ultrasound when hCG >1500–2000 mIU/mL.
3. Continue monitoring symptoms.
