Hi, this is my first time posting so please bear with me! On Friday the 13th of March I took a Sainsburys own brand pregnancy test which came back with a positive result (in the time frame) today Sunday the 15th of March I took a clear blue fast result test and this one is negative? I’m just very confused and not quite sure what to make of the situation. Was the first an Evap? Do I not have enough HCG for the Clear Blue tests to register? Thank you :)
