On Tuesday I waited 5min and got a bfn. Being the poas addict that I am I opened the stick and left it for another 5mins. There was a v dark blue line. However it was thin and slightly off centre. The same day but a few hours later I did another test and it had a v faint line (could b an evap). Yester day did 2 first responce and got bfn. Today internet cheapies bfn? Any one had a similar experience?
