After becoming pregnant, women must pay attention to actively go for prenatal checkups, so as to better understand the conditions of the fetus at different stages of growth and development. Some women go for prenatal checkups and B-ultrasound examinations during pregnancy and find that the embryo has no embryo bud. When faced with this situation, you should pay attention because it is likely a problem of fetal development cessation, so you should follow the doctor's advice. The absence of an embryo during B-ultrasound in the early stages of pregnancy is not necessarily abnormal. The gestational sac can usually be seen during B-ultrasound examination after 5 weeks of pregnancy (starting from the day of the last menstrual period), and the detection rate of the gestational sac reaches 100% by 6 weeks of pregnancy. The embryo can be seen at 6-7 weeks of pregnancy. On the 49th day of pregnancy, when the diameter of the embryo is 2mm, the primitive heart tube beating can be seen. At 8 weeks of pregnancy, the embryo begins to take human shape. If no embryo can be detected after 7 weeks of pregnancy, it may be due to embryonic maldevelopment. There are many reasons that lead to embryonic arrest, such as inflammation, drugs, environment, immune problems, chromosomal problems and many other factors. Abortion is necessary in a timely manner. Many times, because women do not know much about the various common sense issues during pregnancy, they do not pay attention when some abnormal conditions occur in the body, which will naturally bring adverse effects and harm to the health of the fetus invisibly. Therefore, I hope that after the above introduction, every woman can pay more attention to these issues. |
