Indents on frer???

Anyone else is experiencing horrible indents on FRER?? I’ve bought 2 batches of tests and they all came up with an obvious indent within the 3 minute mark. I decided to test bc I’m 5 days late on my period and currently 8month pp if I was pregnant I should be getting an obvious positive at this point but shame on FRER honestly this can really be discouraging for someone who is actively TTC and hoping for their BFP.
