Both lines faint??

Greer

Ok so this test started off weird...seemed like nothing showed up at first except pink pool...so was like wow that sucks what a waste of a test and left the bathroom. Looked back like 15 minutes later just to see and then both lines are faint. I know I know after the time frame but I don’t actually know that. But it’s so weird. Faulty?? Had to small positive maybe faulty test on blue dye last night. Didn’t see anything with FMU this morning (maybe something) this was with SMU. Thoughts??? Thanks! It’s been four years I hope this is it!
