I have taken all of these today. The top one was done with FMU, middle was SMU and the digital was about an hour later. What does this mean?! The FRER’s were from the same pack, could they be faulty? (Unsure when my period is due, I am spotting brown blood at the moment, I don’t even need to wear a panty liner) according to my app it was 16th of this month but I am a bit out of whack.
