Normal Male DNA, 4th miscarriage

Kayleen

So I’ve had 4 miscarriages in 3 years and we just got the results back after my d&c. I can’t find much information but can anyone tell me why I was diagnosed with a blighted ovum, had a d & c and now the dr says it was a normal male and there is no explanation as to why I miscarried??! Was it NOT a blighted ovum then? My hcg HAD dropped before the d&c so I do know I was miscarrying. Any and all info would be appreciated. Thank you
