Is there a pregnancy sac and yolk sac that will stop the fetus?

Pregnancy sac and yolk sac may also be fetal arrest. Color Doppler ultrasound examination shows that there are pregnancy sac and yolk sac in pregnancy sac, indicating intrauterine pregnancy. At present, embryo development is normal, but fetal arrest can occur at any stage of pregnancy. Now normal embryo development cannot guarantee that fetal arrest will not be caused by chromosome abnormality or taking drugs in the future.
