Confused

Does anyone else have super sporadic OPK’s? I know I didn’t test at the same time everyday which could be my problem, but even on the months I have tested at the same time everyday, my tests looks the same as this month. I haven’t been told I have PCOS, though I do know I have cysts. Also, I got a few negatives after my last test (May 29th) and then today a BLAZING positive. I mean, it pulled most of the color from the control line to the test line. Followed by a negative HPT.
