The decision to preserve the pregnancy depends on the actual situation, first of all, it is necessary to take into account the cause of the preterm miscarriage. In early pregnancy, blood hcg, progesterone, and estrogen are monitored to observe the stability of the pregnancy. If the progesterone value is low, oral progesterone capsules or dydrogesterone tablets, combined with traditional Chinese medicine such as Zhi Kidney Fertility Pill, or Chinese medicine will be used to supplement the luteal deficiency and insufficient progesterone secretion to achieve the effect of fetal preservation. During this period, you should rest in bed and avoid strenuous activities. If you have vaginal bleeding with abdominal pain, you must seek medical attention in time to prevent the occurrence of preterm miscarriage. The fetus will be kept for 3 months, and the placenta will secrete progesterone to maintain the growth and development of the fetus after the placenta matures after 3 months of pregnancy. If you have a medical condition that may cause miscarriage before pregnancy, you should correct it before pregnancy and choose to get pregnant after all health indicators are normal. Once the pregnancy is unavoidable, it is important to start the treatment of fetal retention when the pregnancy is confirmed, and if necessary, hospitalization in the hospital until the fetus is stable. Therefore, if you experience vaginal bleeding with abdominal pain in early pregnancy, you must pay attention to it, seek medical attention in time and follow the doctor’s instructions for fetal preservation treatment.
