Symptoms of fetal arrest include vaginal bleeding, abdominal pain, disappearance of early pregnancy reaction, disappearance of fetal movement and fetal heartbeat. 1. Vaginal bleeding: when the embryo develops normally, the body will gradually secrete all kinds of hormones, which can maintain the embryo in bed and thicken the uterine lining. After fetal termination, the level of hormones in the body will gradually decline, which will lead to the loss of hormonal support of the meconium and shedding of the meconium, and the symptom of vaginal bleeding will appear. 2. Abdominal pain: after fetal termination, the chorionic villi and meconium begin to peel off, and the blood sinus opens up with vaginal bleeding; the peeled embryo and blood stimulate the uterus to contract, and the symptom of paroxysmal lower abdominal pain will appear. 3. Early pregnancy reaction disappears: some women will have early pregnancy reaction around 6~8 weeks after menopause, the hormone level of the body decreases after the cessation of labor, and the early pregnancy reaction disappears, and the pregnant woman will no longer have symptoms such as nausea, vomiting, and breast swelling and pain. 4. Fetal movement and the disappearance of fetal heart: fetal movement occurs after 16~18 weeks of pregnancy, the fetus will stop moving in the uterus after the cessation of labor, and the fetal heart will disappear, no longer have normal pulsation. Patients with symptoms of suspected fetal arrest should consult a doctor in time, and if necessary, have the uterus cleared or induced labor, to avoid delaying the condition and leading to serious consequences.
