PCOS AND FALSE POSITIVES

Jasmine
Hey everyone, 
So I have had pcos for soooooooo long many years and a couple years ago me and my fiancé were trying to get pregnant and of course that never happened. It's been six years and I have heard that women with pcos get false positives all the time with test. But every time I would test I would get a negative until yesterday. Yesterday I tested for the first time in idk how long and we haven't been trying we just have had a lot of changes going on in our lives. I took the test because I've felt weird lately and haven't had my period since like March or April but that's the norm for me and all three test came out positive. So my question is has anyone ever taken a prego test and one came out positive one negative or all came out positive and you went to the dr and they told you you weren't pregnant or even that you were.
