blighted ovum

Madison
Has anyone had a blighted ovum? I recently had an ultrasound the sac measured to date as 6 weeks 1 day and the fetus 5 weeks 6 days, and my levels were 14690. I am worried I may have this, as there was no yolk sac. Can you please share your personal stories as I am not cramping I am having strong symptoms I haven't had with my previous miscarriage.
