How many days after implantation does hCG increase?
HCG refers to human chorionic gonadotropin. Under normal circumstances, human chorionic gonadotropin levels begin to rise approximately one week after the implantation of the fertilized egg.
After implantation of the fertilized egg, women typically start to secrete human chorionic gonadotropin, and a significant increase is usually observed about one week following implantation. If embryonic development is progressing well, HCG levels generally double every few days around 14 days after ovulation, reaching peak secretion levels at approximately 8–10 weeks of gestation. However, if embryonic development is poor, the rate of HCG increase is typically slower.
It is recommended that women undergo HCG testing at the hospital promptly after conception to prevent any potential complications for the fetus. During early pregnancy, avoid intense or strenuous physical activities to reduce the risk of miscarriage. Pregnant women may benefit from consuming nutrient-rich foods such as eggs and soy milk during early pregnancy, which support normal fetal growth and development.
