Only recently started taking LH strip tests so it's a bit new to me, been using Ovia fertility app which suggests my fertile window begins today and ends Wednesday, started taking tests about 10 days ago so I could get used to them and the tests came back quite strong to begin with but nowhere near positive, then the last two days lines have been extremely faint, took another this morning around 9, I had been awake for 3 hours so not first pee of the day and it looked quite positive to me so took another about 12 and got pretty much the same result, does it look positive to any of you? Or not quite? Plus if it is positive does that mean if I ovulate in next 24hrs-36hrs my fertile window is Wednesday and will end Sunday rather than Ovias suggestion?
