Wondering if anyone has any advice? Am 4 days late (normally pretty regular) and despite peeing on -far too many- a few preg tests, have had nothing to speak of ( a couple of proper squinters but not sure if that's just me wanting to see a line). Anyway, I found a test I took 3 days ago with quite a visible line, but I can't see any dye. Is this an evap line? Never had one with a frer before so not sure what they look like. Thanks in advance!
