Vvvvfl HPT and 2 lines on OPKs 1day before AF

So I have been trying for over a year and have had a whirl wind of stress with a couple of time thinking I was pregnant but wasnt ... my AF is due tommorow but had TMI.... CLEAR stretchy stringy CM yesterday when wiping and sore chest, decided to take opk because of the cm, their not positive but all the same two lines so took a frer.... what do you guys think the line is very faint and pic was taken within 10minutes of testing ( not with FMU) but theres colour to it and I'm praying that this will finally be our positive
