The HCG pregnancy hormone has a  wide range of normal levels in early pregnancy. HCG is the abbreviation for "Human Chorionic Gonadotropin". hCG is the "pregnancy hormone" which is being produced by the placenta as soon as implantation happens about one week after fertilization and ovulation. hCG then continues to rise until about 10-12 weeks at which point it will stabilize or drop.
Many women wonder whether they have a normal hCG level or not.

• At hCG levels below 1,200 mIU/ml the hCG usually doubles every 48-72 hours and it normally increaseses by at least 60% every two days. 
• Between 1,200 and 6,000 mIU/ml serum, the hCG usually takes 72-96 hours to double
• Above 6,000 mIU/ml, the hCG often takes over four or more days to double.

It makes little sense to follow the hCG values above 6,000 mIU/ml as at this point the increase is normally slower and not related to how well the pregnancy is doing. After two to three months the increase will slow even further and eventually hCG levels even decline before reaching a plateau for the duration of the pregnancy.

There is really no single "normal" hCG level and there is a very wide range of hCG values as pregnancy progresses.

If you are interested to find out if your pregnancy is progressing normally or not then the most important information is to find out whether your blood hCG level is rising normally or not.
