Cd 50 faint positive opk!!!!Wats this?!?

Hi girls so my cycle has gone totally nuts this 50 at the moment all negative pregnancy tests....decided this morning to use an opk just to see if I could have any hope of ovulation and it was faintly positive...I know they aren't actually positive until the line is dark but now I'm wondering if im close to ov after all. So confused this cycle!!!
