In many early pregnancies, the hCG level will double every 31 to 72 hours. As the pregnancy progresses, hCG levels rise and the doubling time increases.

31-72 hours |
| Between 1200 to 6000 mIU/ml |

hCG levels rise during the first 6 to 10 weeks of pregnancy then decline slowly during the second and third trimesters.
