I'm 12 dpo and I took a frer that had an even fainter line last night. This test pictured is my fmu test. I took another tonight and the line is there but fainter (I've drank a ton of tea today so idk what I was expecting lol). I'm thinking it's just a crummy indent that First Response tests have been giving lately but I guess I'm curious what others think! It's hard to pick up on camera but in person it might be a tad darker than the pic but not much. It has pink to it. Also, the line was there prior to taking it out of the casing. It came up immediately upon the pee running across. The line hasn't change even as the test dried. It's not any darker or lighter since the test dried.
