Has anyone ever had more than one evap line test?? I've TWO out of the same FR packet!!

I tested on DPO14 in the morning (although not with FMU), nothing came up so I threw the test away. When I got home that afternoon I knocked the bin over while mopping and noticed that it had a very feint second line (DH saw it too, I'm not going mad!)... test again, no 2nd line. Put it down to a dud test / evap line.

I, of course, kept both tests and was having a look at them this morning and noticed there is now a line on the 2nd test.

I tested this morning (DPO16) with FMU and got a very definite BFN.

I was just curious if anyone had ever had more than one false positive??

Here's a pic I took this morning, I can't see a line on the 14PM test, but it's definitely there IRL -
