I couldn't wait!

Hello cycle buddies due 5/10-5/11 So this morning I tested with FMU with a FRER test. I technically shouldn't be testing until Sunday probably but I did anyway 😭🤦🏻‍♀️ I saw a line, but no dye to it!!! What does that mean??? I have taken test in the past and I've never seen a line what so ever. Could be invalid? I just don't want my hopes up!!
