The absence of echoes in the uterus at the beginning of pregnancy may be caused by a short period of pregnancy, accumulation of blood in the uterus, ectopic pregnancy and so on.
1. Short pregnancy time: after pregnancy, women go to the hospital to do ultrasound time is too early, the pregnancy time is relatively short, the embryo has just landed, the oocystic membrane of the double membrane structure can not be seen, ultrasound results will be judged to be intrauterine echo-less area.
2. Accumulation of blood in the uterine cavity: in the early stage of pregnancy, there will be accumulation of blood in the uterine cavity when there is vaginal bleeding, and when there is no bleeding, the blood accumulates in the uterine cavity, and the ultrasound examination will also show that there are no echoes in the uterus.
3. Ectopic pregnancy: when ectopic pregnancy occurs in early pregnancy, there is a false gestational sac in the uterus, and the ultrasound examination result may also be echogenicity.
The echogenicity of the uterus at the beginning of pregnancy should be judged by a professional doctor, and then targeted treatment.
