Thanks for the query.
The possible causes for first trimester miscarriages are:
-Uterine anomalies etc.
Among these Chromosomal anomalies is the most possible cause and usually these won't repeat in subsequent pregnancies.
So this time you continue the pregnancy
under doctor's supervision from the beginning.
