Blighten ovum

Katelyn

I have a question has anyone ever been misdiagnosed with blighted ovum? I had my first ultrasound yesterday according to my last period I was supposed to be 10 weeks 3 days. But my sac was measuring 8 weeks and few days. But we did not see a baby. I go in next week to see if it actually is. Has anyone had this problem and turn out fine?
