Doctor's answer:
Hello, the causes of threatened miscarriage can generally be divided into two major aspects: the pregnant woman and the fetus.

Statistics show that 100% of miscarriages in the first four weeks of pregnancy are, with 75% being chromosomal abnormalities. In miscarriages before 12 weeks of pregnancy, account for about 12%, with 5.3% being chromosomal abnormalities. It is recommended to pay attention to the above causes.
