Fetal abortion can occur at any time during a woman’s pregnancy, and is usually more likely to occur around 6-10 weeks of pregnancy, and less likely to occur after 12 weeks of pregnancy, and most common clinical abortions occur around 8 weeks of pregnancy. There are many causes of embryonic abortion. Usually, the 8th week of pregnancy is a critical period of embryonic development when cells slowly differentiate into adults, and the embryo is easily affected by hormones and its own quality. During the formation of the embryo, external factors that interfere with the normal journey of the embryo can also cause the embryo to stop developing. When embryonic abortion is detected, it is necessary to go to the obstetrics and gynecology department for ultrasound examination to understand the fluctuation of fetal heartbeat, exclude chromosomal and maternal abnormalities, terminate the pregnancy as soon as possible, clarify the cause of embryonic abortion and carry out treatment under the guidance of the doctor. Pregnant women are advised to keep warm during early pregnancy, avoid catching a cold and take folic acid in time.
