The conclusion after the ultrasound is another sign of early pregnancy. However, in too early terms, ultrasound cannot serve as a 100% guarantee, since the future embryo, until it has reached a certain size, the doctor may not notice. When performing this instrumental study, in addition to confirming pregnancy, the following indicators are revealed:
• localization of the fetal egg (in the uterus or in the tube, ovary, etc.);
• determination of the viability of the embryo (whether there is a heartbeat);
• the presence of the embryo itself in the fetal egg (detection of anembryony).
