Okay I have had multiple positive tests (all blue). Been trying to get one via FRER and have failed. Digital is negative too. Now, I took an FRER earlier today and saw a VERY feint line. I just looked at it again and the line is a lot more present. I know it's past the 10 mins.. But what should I think of it? I have attached pics of the positive tests and then the picture of the FRER earlier, and now.
