Still getting positive OPK's??

Tania

I've studied the box and the test over and over! How the hell am I still getting a positive OPK at 9DPO? Idk why but I randomly just took this to see what the results say. I even posted what the instructions say with the picture just to show that I know what I'm looking at. Test line is to be darker, or similar in color as the control line for it to be a positive. The test line is way darker. Any other ladies have this?
