Such early termination of pregnancy
could be due to a variety of causes. Like chromosomal abnormalities in the fetus, strenous activity during the first trimester, any other underlying disease in the mother like anemia
, fetal malformation, etc. You should go back to your OBG specialist, and discuss further on it so that you can take the necessary precautions next time. Hope you come out of the incident. Be well. Thank you.
