I have taken 5 pregnancy tests in the last week. I haven’t been trying to conceive but started to feel that I may be pregnant. My boyfriend bought me some clear blue 6 day early tests. The first 2 came up negative. A couple days later I did another test which has a faint line, it’s definitely got a blue colour to it. I have done another 3 tests since which have all been negative (also not the first pee of the day). With the faint positive I didn’t manage to look for a couple of hours. Now there’s a chance I could be pregnant I’m hoping I am which is scary to say. I am also 6 days late, have swollen and tender boobs, sensitive to smells and many more symptoms that seem to be early signs. Does this look like an EVAP line? Why would all my other tests not show?
