Thanks for your query.
Since you are already into 11th week without any heart beat, its better to go for surgical evacuation of uterus
. There is no point in waiting for more time.
After D&C get a detailed evaluation like thyroid
profile, TORCH infection
, blood sugar, karyotyping of both you and your husband.
However, even after 2 consecutive abortions, chances of successful pregnancy
is 80%. So be tension free .
Hope this helps.
