question: I am 2 weeks late for my period.  I have always been on time like clock work for 20+ years.  I had an HGC test and it was only 2.  I am 42 tears old and am trying on having a baby and am worried that I have a hormone inbalance.  Can it still be too early to accurately have a pregancy reading?  What are some causes for having a late period, if I am not pregnant?  Is not being on schedule, is this something I should be concerned about if I am not pregnant?
