Could all 3 tests have evap lines or mystery lines, or are they very faint positives, pic incl? im so confused?

Did you use First Response where u pee in a cup and then dip the stick into it? I used that one and my 2nd line came up as a faint positive - similar to yours. I wasn't satisfied so i bought a different type of test, where u actually pee on to the stick itself. It was called Discover, One Step. My positive line came up pretty much straight away and it was as dark as the first line. I think you are entitled to do another test without your partners permission... it is nerve racking going to the docs. Try another brand of hpt, and see how you go! Then, if you still aren't happy, I would get bloods then. Good luck!
