HCG has nothing to do with early or late implantation. HCG is produced after the fertilization of the egg, when the trophoblast layer of the fertilized egg is formed. It is produced only after the egg is deposited, so HCG has nothing to do with whether the fertilized egg deposits early or late. Fertilized egg will be laid 6-7 days after its formation. If ovulation is delayed and the formation of the fertilized egg is pushed back, then the time of its implantation will be pushed back as well. At the same time the HCG values will be delayed and the time to detect pregnancy will be prolonged. The time of pregnancy through menstruation will be different from the actual time of pregnancy. During pregnancy, pregnant women should pay attention to balanced nutrition, ensure enough sleep, do not stay up late, and maintain a relaxed mood, which is conducive to the growth and development of the fetus. During pregnancy, you should also pay attention to regular checkups to observe the development of the fetus.
