Question
I had a miscarriage at 11 weeks of pregnancy. When do chromosomal abnormalities typically cause miscarriage?
Answer
Chromosomal abnormalities in embryos or fetuses are the most common cause of early miscarriage, accounting for about 50~60% of such cases. They also account for about one-third of mid-pregnancy miscarriages and only 5% of late pregnancy fetal losses. It is recommended to strictly avoid pregnancy for 3~6 months after a miscarriage. If this is your first miscarriage and both you and your partner are in good health, further testing may not be necessary. However, it is important to remember to supplement with folic acid when planning for another pregnancy.
