Signs of susceptibility to fetal arrest at 8 to 10 weeks are characterized by vaginal bleeding, disappearance of early pregnancy reactions, and abnormal clinical findings (e.g., ultrasound, human chorionic gonadotropin hormone). However, some pregnant women may not show any obvious signs.
1. Vaginal bleeding: If the embryo stops developing, there is a possibility of rejection, which may lead to bleeding reactions, which in turn may manifest as vaginal bleeding.
2. Disappearance of early pregnancy reaction: Due to the decrease in the level of estrogen and progesterone in the body, the early pregnancy reaction, such as nausea, vomiting, and fatigue, will be weakened or disappear.
3. Abnormal results of clinical examination: during ultrasound examination of uterine adnexa, no fetal heartbeat may be found. When blood is drawn to check human chorionic gonadotropin, the value will rise slowly or fall.
During pregnancy, you need to do regular checkups, and timely and targeted treatment when abnormalities are detected, so as to avoid delays in the condition.
