In a normally developing singleton pregnancy, quantitative serum HCG levels double every 2-3 days during the earliest weeks of pregnancy. This HCG calculator can be used to determine the doubling time of your HCG levels.
1 An ectopic pregnancy is likely if there are no signs of an embryo or fetus in the uterus but hCG levels are elevated or rising. 2  Two or more blood tests of pregnancy hormone (human chorionic gonadotropin, or hCG) levels, taken 48 hours apart. 3  During the early weeks of a normal pregnancy, hCG levels double every 2 days. During the early weeks of a normal pregnancy, hCG levels double every 2 days. 2  Low or slowly increasing levels of hCG in the blood suggest an early abnormal pregnancy, such as an ectopic pregnancy or a miscarriage.
