Thanks for the query.
Most common cause of miscarriage
is genetic abnormalities.
Miscarriage is nature's way of discarding abnormal fetuses.
Since you had two consecutive miscarriage i recommend you to get investigated for infections(TORCH).
Start taking folic acid
tablets right away.
Even after 2 recurrent abortions, chances of successful pregnancy
is 75%. So be relaxed and tension free.
Hope this helps,
regards and take care
