Blighted ovum

Jessica

Has anyone on here had a blighted ovum. The sac only measure 6 weeks when I should've been 9 weeks. No baby no heart beat. The doctor never tested my hormones after D&C. So I was wondering how soon it would drop to zero and if I could get pregnant right after having the Miscarriage? It's also been 3 weeks almost 4 since the D&C
