Im confused on this. It's just a cheap dollar ovulation test. And when ive read on here that the test line has to be has dark as the control line for it to be positive. But when reading the box it doesn't say any of that. It says if I get a line on the test line I will be ovulating within 24 to 48 hours. My cycle has been really crazy lately so ive been keeping up with my cm to help me see if im ovulating.. And I've had heavy watery cm. Please help should I just go by the box and hope ill be ovulating soon or is this a completely negative test?
