After pregnancy, different prenatal examinations should be performed at different stages, and B-ultrasound is an essential examination during pregnancy. It not only observes the condition of the uterus, but also the development of the embryo. The gestational sac is the primary examination item. But some women just can't see the gestational sac, so why can't they see it all the time?
There are two main reasons why the gestational sac cannot be detected during pregnancy. The first reason is that the number of days of pregnancy is too short. If the number of days of pregnancy is not enough, the gestational sac cannot be seen by ultrasound. Therefore, it is generally recommended to look for ultrasound after five weeks of pregnancy, as the gestational sac can usually be seen. Another reason is ectopic pregnancy, and the last reason may be due to biochemical pregnancy.
If the gestational sac is still not visible after enough days of pregnancy, it is necessary to draw blood to check for progesterone HCG， And a three-day dynamic blood test is required to monitor the development of El dynamically. If the blood HCG growth is still not good after three days of dynamic blood sampling, it is highly suspected of ectopic pregnancy.
If the blood value gradually decreases and the gestational sac cannot be seen, the possibility of biochemical pregnancy is relatively high. There are many reasons that can cause biochemical pregnancy, which may be related to the factors of sperm and egg itself, hormone levels, or antibody infections.
After pregnancy, it is important to pay attention to rest, ensure sleep, and avoid staying up late and overworking. Pay attention to personal hygiene in daily life, do a good job in cleaning the external genitalia, and change underwear frequently. Diet should also be light and easy to digest, which is beneficial for pregnancy health.
