What does this mean?

Can PCOS cause false positive tests? I took 3 pregnancy tests a few days apart.. each one was a faint positive…. And the line came up almost immediately… So this morning I wanted to take one more pregnancy test to see if the line would show up dark enough for a digital one and that showed up negative…. So I took another one… and again negative…. Idk what is going on… I am having symptoms…. I got 3 faint positive tests…. Idk what this means… am I crazy? Am I pregnant? were those false positives? Or are these false negatives?? If that is even a thing?

The ones on the bottom are 2 of the 3 positive tests I got and then the top 2 are the ones from this morning…..

what do I do?
