My hgc level is 82,984 and my lmp was oct 27,2010 how far along am I?

There is no way to tell as the range in levels is extremely wide throughout pregnancy. The main benefit for knowing hcg levels is to determine a pregnancy is present and to check if the level is rising in the beginning which would show an increase in the likelihood of a sustainable pregnancy.

With your lmp, however, you would be considered just about 10 weeks for a gestational age.
