At 31 days of pregnancy, also known as 31 days of menopause, the hCG value is roughly between 100-1000 Iu/L. Women with shorter menstrual cycles may have slightly higher hCG values, and if the fertilized egg is transplanted into the uterine cavity later, the values may be slightly lower. The range of hCG values varies widely from woman to woman. hCG values in women who are not pregnant are below 10Iu/L, and above this value early pregnancy is generally suspected. When a high hCG value is first detected, it is not possible to determine whether it is a biochemical pregnancy, an intrauterine pregnancy or an ectopic pregnancy. The diagnosis of normal intrauterine pregnancy can be confirmed only if the hCG value doubles as the number of days of menopause increases, which corresponds to the gestational week, and if the gynecological ultrasound shows the growth of a gestational sac in the uterine cavity. When the hCG value is checked, it is also important to observe whether the woman has any discomfort such as lower abdominal pain or vaginal bleeding.
