The vague pain in the stomach after successful transplantation does not matter in most cases as long as there is no vaginal redness or coffee-colored discharge. After successful implantation of the fertilized egg in the endometrium, the trophoblast cells will secrete a large amount of human chorionic gonadotropin, which will cause occasional vague abdominal pain, which is a normal pregnancy symptom. With the prolongation of pregnancy, pregnancy reactions such as nausea, vomiting, fatigue, drowsiness and reduced appetite will occur. It is recommended to pay attention to rest after in vitro transplantation, preferably bed rest in the first few days, avoid strenuous exercise, pay attention to a reasonable diet, do not eat cold and stimulating food to avoid diarrhea. Try to avoid viral infection and ionizing radiation, and pay attention to folic acid supplementation, which can prevent neural tube malformation in the fetus.
