Why is my hCG so high?

What Causes High hCG Levels? According to Dr. Lang, extremely high levels of hCG (greater than 100,000 mIU/mL) may represent an abnormal pregnancy. Causes may include a placental tumor or molar pregnancy, in which a non-viable egg implants in the uterus and secretes the hCG hormone.

Well, studies have shown that 85 percent of normal pregnancies will have a 66 percent rise or greater of HCG over 48 hours. This does not last all through pregnancy–usually just through the first four-six weeks. When the HCG rises appropriately, there is a much lower chance of ectopic or miscarriage.
