Ovulation tests

Hi everyone!  I just have a question about my ovulation kits. I just started using the clear blue ovulation test this month and have been testing now for a week and a half and still no positive sign. Is it possible that I am not going to ovulate this month and does that mean I won't get my period when it is due?  I am pretty regular with my period and my cycle is about 34 days.  I am trying not to get fustrated or stressed, I just don't understand. On the Glow calander it tells me each day is my fertile day but once I log it moves to the next day. Should I keep testing or hold off for the rest of the month?  Thanks everyone. And good luck!!!
