Why can't I see the gestational sac on ultrasound?

Many women will try to determine whether the fetus is normal by checking the gestational sac after they become pregnant. It should be said that if the gestational sac is normal through B-ultrasound examination, it means that the woman is conceived normally and the fetus is normal. However, if the gestational sac cannot be seen during B-ultrasound and it has been confirmed that the woman is pregnant, then it is very likely that fertilization is late, or the fertilized egg implants too late, or there is an ectopic pregnancy. Of course, no matter what the situation is, further examination is recommended.

First, if you are two months pregnant and still don’t have a gestational sac, it may be that the development has stopped, or if your menstruation is delayed. It is recommended to check again after about a week. If the condition persists, there is a high possibility of pregnancy arrest and abortion should be considered. There are many reasons for this situation. It is recommended that both men and women do a comprehensive pre-pregnancy check-up before the next pregnancy. If there are any problems, actively seek treatment to prevent and reduce the chance of recurrence.

Second, if no gestational sac is seen after 60 days of pregnancy, it is possible to consider an ectopic pregnancy, or it could be caused by biochemical pregnancy, spontaneous abortion, etc. In this case, it is best to have a blood test for hcg to check the secretion of progesterone. If no gestational sac is seen in the later stages, a uterine curettage can be performed, or blood-activating drugs can be taken for treatment.

Third, if the gestational sac is not seen at 60 days of pregnancy, it cannot be ruled out that it is due to late fertilization. If you have been confirmed to be pregnant and no gestational sac is found during B-ultrasound examination, it may be that the fertilized egg has implanted too late. It is recommended to observe closely first, check again after one week, and go to the hospital for treatment in time if you feel any discomfort.

Fourth, generally speaking, the gestational sac should be visible at 55 days of pregnancy, but it may be that the gestational sac is too small and cannot be detected. It is recommended to observe closely and check again after one week to see whether the gestational sac can be seen and treat the symptoms accordingly.

The above is the possible answer to the question of why the gestational sac cannot be seen on the ultrasound at 60 days of pregnancy. Generally speaking, the gestational sac can be seen on the 55th day of pregnancy. If it is still not seen on the 60th day, further examination is recommended. If it is a fetal arrest or ectopic pregnancy, it must be dealt with as soon as possible, otherwise the pregnant woman may be in danger.
