Ovulation kit help!!

I have the clear blue advanced kit that I spent good money on. Ugh! Yesterday took the test the "stick" in the photo started flashing then it was a circle no smiley face so I know I had no hcg. Today tried to take it again. The solid stick will not flash. I've tried 3 tests and it will not work. How do I get t working again? I followed direction. Peed in a cup. Put the test in straight down for 15 seconds and nothing... what am I doing wrong? I've wasted 3 tests today.
