Hey FGS, I have every intention of poas as well. For me it is too emotionally dangerous to hang everything on one phone call where as if I poas like you have done over a series of days maybe I can gradually accept a negative.
Having said that you are still 4 days out from testing and as cliched as it sounds it may well just be too early - I see keep peeing for the next four days you just may see that second line start to appear!!!!
