What is the normal HCG level at 39 days of pregnancy?

　　HCG generally refers to human chorionic gonadotropin (hCG). At 39 days of pregnancy, the normal hCG level typically ranges from 1,000 to 50,000 IU/L, though this may vary among individual women.

　　Human chorionic gonadotropin is a hormone secreted by the trophoblastic cells of the placenta and rises rapidly during early pregnancy. At 39 days of gestation, the typical normal hCG range is 1,000–50,000 IU/L. However, this reference range serves only as a general guideline, as significant inter-individual variation exists. Differences in ovulation timing may lead to variations in hCG levels. For instance, delayed ovulation results in later implantation of the fertilized egg; thus, at 39 days of pregnancy, hCG levels may be relatively lower. Nevertheless, as long as hCG levels double appropriately over time, this is generally considered normal.

　　Abnormally low hCG levels may indicate poor embryonic development or ectopic pregnancy, whereas excessively high levels could suggest multiple gestation or molar pregnancy. Therefore, in addition to assessing hCG concentration at 39 days of pregnancy, comprehensive evaluation—including ultrasound examination—is essential for determining embryonic status.

　　Pregnant women should maintain a light, healthy diet and attend regular prenatal check-ups to monitor their health and support optimal fetal development.
