How high is HCG approximately 17 days after intercourse?

　　HCG refers to human chorionic gonadotropin. Seventeen days after intercourse, if pregnancy is successful, the level of human chorionic gonadotropin will rise and may approach or slightly exceed 100 U/L, typically not exceeding 5000 U/L.

　　Generally, seventeen days after intercourse, if pregnancy occurs successfully, the level of human chorionic gonadotropin may be close to or slightly above 100 U/L and could reach several thousand U/L, but usually does not exceed the typical upper limit in early pregnancy, which is 5000 U/L. However, these values are not absolute, as individual physical conditions and physiological states vary, leading to differences in specific HCG levels.

　　In early pregnancy, HCG levels rise rapidly, typically doubling approximately every two days. Therefore, a single test result alone cannot definitively confirm the pregnancy status; clinical symptoms and additional medical evaluations are needed for a comprehensive assessment.

　　Regular prenatal checkups should be conducted throughout pregnancy to ensure the health of both mother and baby.
