Pregnancy can be continued if the ultrasound examination indicates that the embryo is alive and the pregnant woman has no other related symptoms. Pre-eclampsia usually refers to a series of symptoms such as vaginal bleeding and paroxysmal abdominal pain before the 28th week of pregnancy. If the symptoms disappear after rest and the related maternal indicators are in the normal range, the pregnancy can continue and care can be taken. If the symptoms worsen, as well as the embryonic dysplasia on ultrasound, and the blood HCG continues not to rise or fall, it is difficult to keep the pregnancy and needs to terminate it early. If this is not done, it can have adverse effects on the mother and the risk of neonatal defects is high. Therefore, treatment should be carried out under the guidance of the doctor and follow the medical advice, do not blindly keep the pregnancy. After a preterm miscarriage, you should rest in bed, have regular checkups, reduce squatting, avoid bumps and jarring movements, and pay attention to psychological guidance to prepare for another pregnancy.
