Women experience various pregnancy reactions to different degrees after conceiving, such as nausea, vomiting, loss of appetite, and fatigue. These are primarily caused by hormonal changes in the body following pregnancy. When there is a case of embryonic arrest, the hormones in the body will gradually decrease, and the pregnancy reactions will also gradually weaken. Some may also experience abdominal pain and vaginal bleeding. Therefore, after embryonic arrest occurs, some pregnant women may exhibit early signs, such as the disappearance of breast tenderness and vaginal bleeding, along with a reduction in pregnancy reactions. These signs indicate that timely treatment is necessary.
