Patient's question:
NoDoctor's answer:
Ultrasound examination can detect the gestational sac after 5 weeks of pregnancy, and the detection rate of the gestational sac reaches 100% at 6 weeks of pregnancy. From 6 to 7 weeks, the embryonic germ can be seen, and the primitive heart tube can be observed when the embryonic germ diameter is 2mm. By 8 weeks of pregnancy, the embryo takes on a human-like shape. Doing an ultrasound too early is difficult to see the shadow of the gestational sac, as it is too small. The ideal time is 8-10 weeks of pregnancy when it is easier to see. Moreover, doing an ultrasound too early theoretically may shake the fragile, newly formed embryo, which is not conducive to embryonic development. It is best to avoid doing an ultrasound too early.
