Thanks for the query.
could be due to many reasons like genetic predisposition, infection, anemia
, nutritional deficiencies, hormonal
imbalance and other medical problem.
So you need to consult tour Gynecologist for proper examination and pin point the cause of repeated miscarriage.
Even with 2 consecutive abortions, chances of successful pregnancy
is as high as 80%. So you need not worry.
Hope this helps,
