Is such high HCG normal?

The beta-hCG score of 17.2 mIU/ml, which you obtained 4 days before the expected menstruation, is relatively high and could suggest an early pregnancy. However, the level of beta-hCG changes very quickly, usually doubling every 48-72 hours, so the value of 9.1 mIU / ml, which you obtained 2 days before menstruation, already indicates a decrease in beta-hCG levels. However, the result of beta-hCG hormone determination for a woman in the first weeks of pregnancy should be more than 5 mIU / ml. Spotting at the beginning of pregnancy is often confused with menstruation. This is because this spotting usually occurs at about the expected time as the expected menstruation. In addition, this bleeding can be as heavy as the normal period. The level of beta-hCG (human chorionic gonadotropin) increases in the case of pregnancy, as it is a hormone secreted by the placenta early in pregnancy. Beta-hCG levels may also increase for other conditions, such as cancer in both women and men (testicular cancer, ovarian cancer), ectopic pregnancy, or hormonal disorders. It is difficult to assess what is causing such fluctuations in beta-hCG levels based on such a brief description. In this case, I encourage you to make an appointment with the attending physician and discuss the results of beta-hCG.
