Is it because the pregnancy suddenly stopped?

Pregnancy reaction, generally speaking, in early pregnancy will be more obvious, especially within two months, but two months later will gradually reduce, most people in three months when the early pregnancy reaction is over. Therefore, when a woman suddenly feels no nausea in the early stages of pregnancy, it cannot be used to explain the occurrence of embryonic arrest, or to go to the hospital for B-ultrasound examination to determine the intrauterine development of the fetus. If B-ultrasound examination shows that the fetus is well developed and the heartbeat is visible, it indicates that the fetus has no problem and does not need to be too nervous. If B-ultrasound examination finds that the gestational sac shrinks and atrophies, even from the original embryo and heartbeat to the current no heartbeat, it is considered to be embryonic arrest. If embryo arrest is considered, it is recommended to prevent excessive residual time, resulting in intrauterine infection and massive bleeding.
