Missed miscarriage?

I had a ultrasound on 6/23 measuring 5 weeks 2 days. 15 days later I had a repeat ultrasound

I should have been 7 weeks 3 days. However i only measured 6 weeks 5 days and there was no heartbeat. Doctor said it's a missed miscarriage and D&C was scheduled. Has anyone else ever had something similar happen with a happy ending.
