It is not necessarily hopeless if the transplant does not implant for 7 days. After transplantation, the time for the fertilized egg to implant varies from person to person due to differences in physique, living environment, nutritional status, etc. Some people implant earlier while others implant later. Some people have an early implantation, while others have a late implantation. Generally, the fertilized egg implantation occurs 7-10 days after transplantation. If you haven’t implanted the egg in 7 days after transplantation, you should pay attention to the review for the time being. It does not mean that there is no hope, there is a possibility that its bedtime is later. Usually 10-14 days after the transplantation, blood will be drawn to check the HCG (human chorionic gonadotropin) value to find out whether it is successful or not, and whether the transplantation is successful or not. After in vitro fertilization, keep your mood happy and don’t be overly nervous. If irregular vaginal bleeding occurs, go to the hospital in time.
