My hcg level was 43,996 how many weeks am i ?

It doesn't correlate: The HCG level does not tell you the number of weeks into a pregnancy. It would be like asking, "I'm driving 87 miles per hour, so how far from Los Angeles am I?" Nobody can tell. A study of over 8000 women shows how wide the HCG range can be. It found women with an HCG in the 40,000's anytime between 7 and 37 weeks of pregnancy.
