At 6 weeks heartbeat;at 7 non but some growth.no symptom of miscarriage. without checking hcg or 2nd ultrasound sent for d&c.is that rushed decision?

D&C/necessary?: Yes, it is a "rushed decision" since a serum HCG level should give indication of levels expected for the wks of pregnancy, and another ultrasound with a different sonographer should help significantly with the correct diagnosis.

No heart beat: If there was a heart beat seen previously and now a heart beat is not seen then one can feel confident in diagnosing a miscarriage. Checking a BHCG is not useful if the doctor was able to visualize a heart beat previously and now one is no longer present. The BHCG might rise, fall or stay the same and would not be useful. A lack of a fetal heart rate is definitive
