Pregnant women will regularly go to the hospital for prenatal check ups during pregnancy, and ultrasound is the most common item in prenatal check ups. Generally, pregnant women will undergo several ultrasound examinations during pregnancy. Ultrasound examination technology can determine the health status of pregnant women through various types of echoes in their bodies. So, what happened to the lack of echo around the gestational sac during pregnancy?
If there is no echo around the intrauterine sac, it means that the gestational sac has not been detected. Generally, the gestational sac can be seen in pregnant women after about 40 days of pregnancy, but if pregnancy occurs later, the appearance of the gestational sac may also be delayed. After about 35 days of amenorrhea, early pregnancy testing can be done, and during this period, the echo of the gestational sac can be seen under ultrasound. A week later, another ultrasound review can be done to determine the specific situation.
Early ultrasound examination is difficult to detect the gestational sac because it is still relatively small at this time. And not every doctor can see accurately, doctors with rich imaging experience will be better. Ideally, the gestational sac can be examined between 8-10 weeks of pregnancy.
If there is no echo around the cyst detected by ultrasound, it may be because no gestational sac was found in the uterus. If you do ultrasound examination too early, it is likely to shake the formed embryo, which is still relatively fragile. Therefore, it is best not to do ultrasound examination too early or multiple times to avoid affecting the normal growth and development of the embryo.
