Question about ovulation test

So I am bleeding right now but like light bleeding and I have a cramp on my right side. I took an ovulation test for the heck of it. Somehow whenever I have my period I never have a second line on my ovulation test always one line. But today after I took it I have 2 lines but I know it’s negative for light lines on ovulation test but it still came with 2 lines. What does that mean?
