I used a Clearblue ovulation test for the first time today and I'm a little confused. The test results came back in about I would say 3 to 4 minutes. But the circle like it shows on the box was not 100% a complete circle there was a space left open at the bottom of that circle. And when I ejected the test strip from The clear blue digital tester there are two blue lines on the test strip where the urine test and Control line is. Has anyone ever seen this before? Know if it's normal? Or know what exactly it means.
