During the process of fetus preservation, the pregnant woman can not visually judge whether the bruising is an improvement phenomenon, but also need to make a comprehensive judgment according to whether there is abdominal pain, blood HCG and progesterone value and ultrasound examination: 1. Successful fetus preservation: the symptoms of vaginal bleeding and abdominal pain are gradually relieved, and the embryonic tissue in the uterine cavity is developing normally through ultrasound examination, the obvious fetal heartbeat is visible, the blood HCG value is increasing at a good rate and the progesterone value is in the normal range. If the fetus is successfully preserved, it is still necessary to pay attention to rest and keep a happy mood on weekdays; 2.Unsuccessful in preserving the fetus: the symptoms of vaginal bleeding and abdominal pain persist, and the progesterone value and blood HCG value of the blood test do not rise or fall, which means that miscarriage is more likely. At this time, the doctor needs to decide whether to continue the fertility preservation treatment according to the embryo development. If the embryo is found to have stopped developing after ultrasound examination, the pregnancy should be terminated and the uterus should be cleaned up in time to avoid the residual embryonic tissues which may lead to massive vaginal bleeding and uterine infection. Therefore, the success of fetal preservation cannot be judged only by the discharge of bruises, but should be clearly diagnosed by ultrasound examination at the hospital on time. During the treatment period, it is important to keep your emotions well regulated and optimistic. At the same time, you should pay attention to a balanced diet, preferably rest in bed, and exercise moderately to facilitate fetal development.
