After successful conception, the fertilized egg will develop and grow inside the uterus, forming a gestational sac and embryo. Early pregnancy is a dangerous stage and can easily lead to such problems. Therefore, women need to take good care of themselves in all aspects. So, what is the reason for not having an embryo or embryo?
The absence of embryonic germ may be caused by chromosomal abnormalities. Once the quality of sperm or egg is poor, even if a fertilized egg is formed, the embryonic germ cannot develop normally, so the presence of germ will not be observed during examination. Furthermore, environmental factors during pregnancy are also crucial. If women are frequently exposed to toxic chemicals, it can hinder the growth of fetal buds.
The appearance time of embryonic germ varies from person to person. Although most cases occur at five or six weeks of pregnancy, if the conception time is later, it may not appear so quickly. Women can wait for a week before going for a follow-up examination. If there is no fetal heart rate or fetal bud, one should be alert to the occurrence of fetal arrest. This situation needs to be dealt with in a timely manner to avoid infection in the uterine cavity. Women should also understand the reasons for fetal arrest to prevent it from happening again in the next pregnancy.
During pregnancy, the body's resistance decreases, and when a woman experiences a cold or fever, taking medication indiscriminately can also affect the development of the fetus. If you have infectious diseases during pregnancy, it will not only cause abnormal germ growth, but also easily lead to uterine contraction and abortion.
