After a certain stage of fetal development in the mother's body, it is normal for the fetus to develop a fetal bud and heart rate. The gestational sac is also related to the development of the fetus, and the above conditions can be used to judge the standard of fetal development. Expectant mothers should learn from this. So, how long after having a gestational sac does it take to have a fetal bud?
The gestational sac is formed at 30-40 days of pregnancy, the fetal bud is formed at 40-50 days of pregnancy, and the fetal heart is formed at 50-60 days of pregnancy. However, there are also cases where women with irregular menstrual cycles, late ovulation, and late implantation of fertilized eggs may have relatively delayed appearance of fetal buds, fetal heart rate, and vascular pulsation in the uterus. It is recommended to observe for a week and then go to the hospital for a follow-up examination. The following are the reasons for the absence of fetal buds:
1. Chromosomal abnormalities: Whether it is sperm or egg, if the chromosomes carrying genetic material are abnormal, even if a fertilized egg is formed, the embryo will not develop normally.
2. Exposure to toxic substances: Harmful substances include toxic chemicals, inferior decoration materials, and so on. If pregnant women come into contact with it, it can affect the growth and development of the fetus.
3. Taking medication that affects fetal development: Some early pregnancy symptoms are similar to those of a cold, and the menstrual cycle is not very regular. Therefore, many people mistakenly take cold medicine without knowing they are pregnant. In addition, there are also some chronic disease patients who accidentally conceive without being prepared for pregnancy while taking medication for a long time, which is also a major factor affecting the development of fetal buds.
