Went to walmart. Got a 3pack of FRER, 2 pack of answer and 1 equate.
Came home and used a FRER w/ a 4hour hold w/ no drinks so it was pretty concentrated.
A faint 2nd line appeared on the FRER within a minute or so. It's SO faint though and w/ the problems people have been having with FRERs I'm so hesitant to get my hopes up.
At least I have more tests now. Not gonna take any more tonight and just hope that tomorrow something darker will show up.
