Stupid blue dye tests...😒

So I tested early last week since I was not having my normal PMS symptoms. Very different than usual. Anyways, Thursday  evening I got a very faint line on a blue dye test, tested Friday morning and tested sunday morning all the same thing with yesterday looking  darker. So today, I tested with a FRER test and got a BFN, I mean not even a freaking line. Talk about a punch in the gut. It's going on two years now and after my ectopic in October, I'm slowing loosing hope. Anyone else had this issue with those stupid blue tests?? 😑
