Fetal development requires a certain process. In the early stages of pregnancy, the fetus has not yet formed, so through examination, the gestational sac can be seen, but the formed fetus cannot be seen. The gestational sac is the initial form of the fetus and can be seen in the hospital as early as 35 days after amenorrhea. At this time, the gestational sac is also very small. However, why is the gestational sac transparent?
Under normal circumstances, the gestational sac is transparent and elliptical in shape. As the gestational age increases, the gestational sac gradually becomes larger and rounder. If the size of the gestational sac is normal and there is a normal fetal heartbeat, it indicates that the embryo is developing well, so women can rest assured.
The development of the gestational sac is very important for pregnancy. Only when the gestational sac develops well, the fetal bud and heart rate will also appear as early as possible. The gestational age of a woman can be calculated from the last menstrual period, around 42 days of pregnancy. The gestational sac is about 1.5 centimeters long, and the development of the fetal bud can also be seen. Therefore, regular prenatal checkups are needed during pregnancy to understand whether the fetus is developing normally and to detect abnormal problems in a timely manner.
If the shape of the gestational sac is irregular and accompanied by abnormal conditions such as bleeding and abdominal pain, it is necessary to be alert to the occurrence of threatened miscarriage. It is necessary to go to the hospital for examination in a timely manner and receive fetal protection treatment. During this period, pay more attention to rest and regularly check the condition of the fetus. If the gestational sac does not appear and the presence of fetal heart and fetal buds is not observed, it is possible that fetal arrest has occurred.
