The successful implantation of a fertilized egg means a successful pregnancy. After the fertilized egg has completed implantation, the menstrual period that should have been on time will not be on time. Women who are preparing for pregnancy or who have had unsafe sex should consider the possibility that the fertilized egg has successfully conceived if they experience delayed menstruation. To confirm that the egg has successfully fertilized and conceived, a blood HCG test or a urine test for early pregnancy should be done at the hospital. If you want to determine earlier whether a fertilized egg has been fertilized, you can have a blood HCG test done around day 7-10 after intercourse for a definite diagnosis. Some women may experience a small amount of bleeding during the process of fertilization. When there is a small amount of bloody discharge around 7-10 days after intercourse, a blood HCG test can be done to confirm whether the fertilized egg has been fertilized.
