Negative Pregnancy Test After Positive: 4 Explanations & Next Steps

A negative Clearblue following prior positives suggests:

1. Early pregnancy loss (chemical pregnancy) – hCG rises then falls; may bleed.
2. Ectopic pregnancy – hCG rises abnormally, then plateaus/drops; EMERGENCY if pain/bleeding.
3. hCG trigger shot residue – from fertility treatment; clears in 7–14 days.
4. Evaporation/indent line – read outside window; not a true positive.

Action: Quantitative serum β-hCG ×2 (48 hrs apart) + transvaginal ultrasound. Contact OB-GYN immediately if pain, bleeding, or uncertainty.
