Issues with FRER new style

Arie
Ladies, have any of you also experienced This? I have taken 5 FRER tests this week.. first one showed vvvfl second one 2 days later was even lighter-almost gone, 2 days later took another which was faint but darker (took a CVS brand early response test which was obviously positive) 2 days later I took 2 more FRER tests, both negative with horrible indents which I could see as soon as the test got wet, CVS brand test still obviously positive... I did start spotting so I'm not expecting this to work out, but what the heck with these tests? I thought they were supposed to be the best, most sensitive.. why is CVS brand showing positive and these aren't? What a waste of money and I feel more confused than ever. I'm including a pic of the tests I just took this morning. Any opinions would be appreciated.
