The hCG blood levels 

Human Chorionic Gonadotropin (hCG) is the hormone produced during pregnancy. hCG levels can vary widely so it should not be used to date a pregnancy. There are two common types of hCG  blood tests: qualitative and quantitative

  • A qualitative hCG test detects if hCG is in the blood. 
  • A quantitative hCG test (or beta hCG) measures the amount of hCG in the blood.

The placenta is the sac that nourishes the egg after it’s fertilized and attaches to the uterine wall.During pregnancy, cells in the placenta make the hCG hormone. 

Ultrasound at 8 weeks

HCG can first be detected in about 11 days after conception. During a healthy pregnancy, levels of hCG double every 48 to 72 hours. They reach their peak around eight to 11 weeks after conception. HCG levels then decline and level off and remain steady for duration of your pregnancy.

This table shows the normal hCG levels during pregnancy for each week from your last menstrual period, according to the American Pregnancy Association:
