FRER help (please) <3

Okay.. So I got a positive opk on the 24th.. So if I ovulated on the 25th, today (the 5th) would be my 10dpo. I've had multiple positive pregnancy tests. All blue, one possible FRER. My husband isn't taking any of it as a possibility because I have "altered" the photos (darkened/ contrasted them) to pull out the color. So I took an FRER tonight (very undiluted urine) and this line shows up when I take it and then turns negative. Nothing. Nada. I took another one thinking it was a faulty test because I have never seen that before.. Same thing. Is this normal? I have attached a pic of the line I'm talking about. Then I have attached pics of my positives I have had. I'm wondering if something is wrong and if I need to go to the dr ASAP.
