The development of an embryo requires a complete process, so the fetus does not have a shape from the beginning. After 35 days of pregnancy, the embryo sac will appear, and then the fetal heart and embryo buds will also form. Women can go to the hospital for ultrasound examination to understand the development of the intrauterine gestational sac and see traces of the fetal heart and embryo buds. However, what is the reason for having an embryo but not a embryo?
The presence of embryos without embryos may be due to their development being too small to be seen. Many women have unstable menstrual periods, and the fertilized egg implants relatively late. Therefore, at this time, the embryo may not have developed yet or may have developed very little and not been seen. It is recommended that women wait for a period of time before going for a follow-up examination. If there are embryos present after the re examination, there is generally no major problem.
Embryos can generally be detected at 6-7 weeks of pregnancy. If there is no embryo and no fetal heartbeat after re examination, it should be considered that fetal arrest has occurred, which may be caused by chromosomal abnormalities and the result of natural elimination. Therefore, women should not be too sad and should actively undergo examinations to prepare for the next pregnancy.
Once fetal arrest occurs, women should go to the hospital for treatment as soon as possible. If the fetus remains in the uterus for too long, it can have a significant impact on the body. To avoid embryonic arrest, women should actively take care of themselves in all aspects before pregnancy, and also undergo comprehensive pre pregnancy examinations to understand their own physical condition.
