Yeah, it's a FRER. I didn't see anything so I took the case off thinking I would be able to see something more....I did :)
What kind of test was it?? Is it a FRER and you took it out of the casing?? LOL I do that too!!
Its a positive its faint but there. Thats how mine was. I wanted two days and tested again and it was so mych darker! Congradulations!
