Waterline or fainted positive????

Me and my fiancé have been trying for a baby for over the past 3 months now, constantly having unprotected sex and constantly trying to make a baby! Every month since I’ve been missing a period so I’ve been taking many , many tests one after the other for weeks , PRAYING it said positive , but it never has! My period is now 26 days late and still no sign of blood whatsoever! I’ve done at least 6 pregnancy tests since the first day of my missed period (25 days ago!) and they have all came up negative 🤦🏻‍♀️. I took this one last night and it came up negative straight away so I left it on the bedroom table , then me and my fiancé woke up and he noticed it had the faintest line on it , and I got so happy I started crying a little bit but I didn’t wanna get my hopes up at all in case it’s just a water line, so that’s my questions girls , is this a waterline or a faded positive?? I’m so confused and dying to know! I tried to make early doctors appointment so they could take blood tests but I never got an appointment til Monday now and I just can’t wait to find out what’s really going on 😩 .
