<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?
