Below is the chart for the normal HCG range during
pregnancy. You can see the range is huge. There are a couple
of different reasons for it...multiples (yes, one can be hiding the first ultrasound), molar pregnancy or partial molar pregnancy (not very common). Also, just one of those things. My OB told me that less and less is being made of HCG values, mainly because early ultrasound is a better way to date and keeping your eye on a pregnancy. Chances are it is nothing to worry about.
