Hi saramac
I dont undertsand a lot about those charts and attempting gender selection, Im sorry. But I do know that any HCG level over 5 is considered 'pregnant'. The HCG level its self needs to double/ triple every 24- 48 hours, so one HCG reading wont give a very accurate result iykwim. It may be low but if it is meeting that quota of increase it should not be of concern. HTH
