From what I understand LJ most people go straight to the Dr after a BFP to confirm the HPT by blood test and get a beta level - plus a barrage of info!
I found out I was UTD at the Dr's cos I have PCOS and thought the constant cramping and no AF showing up was another $%@$%**& PCOS symptom - turns out it was classic early pregnancy!
Definately get yourself along to the GP hon
