Hi, thanks for using healthcare magic and sorrry for your loss.
the results on the scan indicate that the miscarriage
was complete, there are no remaining products of conception.
There are different reasons that a miscarriage can occur and it can also vary according the trimester that the miscarriage occurs.
In early pregnancy
it is often due to genetic abnormalities.Other possible causes include:infection, enviromental hazards,incompetent cervix
, hormonal problems, smoking , alcohol use,diabetes
,some medication, inadequate nutrition, kidney disease, heart disease
You may want consider speaking to your doctor to determine if he or she knows the reason for the miscarriage, in some women the exact reason is never known.
I hope this helps and wish you the best
